Radioactive Iodine vs Thyroid Surgery for Hyperthyroidism: What Each Path Involves

The appointment usually ends with a folder. Inside are two leaflets, one about a capsule you swallow once and one about an operation on your neck, and a sentence from the endocrinologist that sounds almost too relaxed: “Have a think about which you’d prefer.” Many people leave that room feeling they have been handed a decision they are not qualified to make.

That reaction is understandable, and it is also the reason this explainer exists. The choice of radioactive iodine vs surgery for hyperthyroidism is not a test of knowledge. It is a weighing of trade-offs that are, for the most part, well described in the medical evidence: how quickly each works, what each can go wrong with, what life looks like afterward, and which situations tip the balance one way.

What follows is the honest version of both leaflets, plus the things people tend to ask only once they are already home.

What does radioactive iodine vs surgery for hyperthyroidism actually compare?

Hyperthyroidism is a state in which the thyroid gland, the butterfly-shaped organ at the front of the neck, releases more thyroid hormone than the body needs. The result is a metabolism running hot: a racing heartbeat, heat intolerance, tremor, anxiety, weight loss despite a good appetite, and sleep that never quite lands.

There are three broad ways to bring that hormone level down, and the NHS and Mayo Clinic describe them in the same order. Antithyroid medicines slow hormone production but leave the gland intact. Radioactive iodine (often shortened to radioiodine) uses a radioactive form of iodine to damage hormone-producing cells from the inside. Surgery, called thyroidectomy, physically removes part or all of the gland.

The last two are grouped together as “definitive” treatments because they aim to change the gland permanently, rather than hold it in check for as long as a tablet is taken. So the comparison in this article is really about two routes to the same destination: a thyroid that can no longer overproduce.

That framing matters because it sets expectations early. Both paths very commonly end with an underactive thyroid, and therefore with lifelong thyroid hormone replacement, a daily medicine that stands in for what the gland used to make. Mayo Clinic is explicit that radioactive iodine causes thyroid activity to slow considerably and often leaves the gland underactive; total thyroidectomy makes replacement unavoidable. People sometimes hear “definitive” and imagine walking away with no thyroid concerns at all. The more accurate picture is trading an unpredictable overactive gland for a predictable, manageable underactive one.

Everything else in the decision is about how you get there: speed, certainty, risks along the way and what your particular body and life require.

Why the cause of your hyperthyroidism shapes the choice

Not all overactive thyroids are the same, and the underlying cause is often the first fork in the road.

Graves’ disease is the most common cause. It is an autoimmune condition in which antibodies mistakenly stimulate the whole gland, so the entire thyroid overproduces. Because the problem is diffuse, both radioactive iodine and surgery are reasonable definitive options, and Graves’ disease is where most of the “which one?” conversations happen.

Toxic nodular disease is different. Here one nodule (a lump within the gland) or several nodules become autonomous and pump out hormone regardless of the body’s signals. The NHS notes that nodular causes are also treatable with radioiodine or surgery, but the anatomy influences the pick. A very large multinodular goiter, meaning an enlarged thyroid with many lumps, may press on the windpipe or swallowing tube, and physically removing it can address both the hormone excess and the pressure at once. A single small hot nodule may respond well to radioiodine, which concentrates in the overactive tissue.

Thyroiditis, an inflammation of the gland, is a third category. It often causes temporary hyperthyroidism as stored hormone leaks out, and it usually settles on its own. According to Mayo Clinic, treatment here is about managing symptoms while the gland recovers; neither radioiodine nor surgery is typically the answer, because there is no long-term overproduction to stop.

This is why blood tests, antibody tests and sometimes a thyroid uptake scan (an imaging test showing how much iodine the gland absorbs and where) come before any treatment decision. A team cannot sensibly compare the two definitive paths until it knows which kind of overactivity it is dealing with, and whether definitive treatment is needed at all.

How radioactive iodine treatment for hyperthyroidism works, step by step

The thyroid is the only organ in the body that actively hoards iodine, because iodine is a raw ingredient of thyroid hormone. Radioactive iodine therapy exploits that appetite.

You swallow a capsule or a small drink containing a radioactive isotope of iodine. It travels through the bloodstream, and the thyroid takes it up as if it were ordinary dietary iodine. Once inside, the isotope emits short-range radiation that damages the cells around it. Because the range is so short, the surrounding neck tissue receives comparatively little, which is why the treatment can be given as an outpatient appointment in nuclear medicine rather than as an admission. The NHS describes it as a single treatment for most people, though a second round is sometimes needed if the gland remains overactive.

Preparation is mostly about making the gland hungry. Your team may ask you to pause antithyroid tablets for several days beforehand, and sometimes to reduce iodine-rich foods, so that the thyroid absorbs more of the treatment rather than competing iodine. The exact instructions come from the prescribing clinician and vary by center.

Nothing happens instantly. The damaged cells stop working gradually, and Mayo Clinic notes that symptoms typically subside over several weeks to months. During that window, many people continue a beta blocker, a medicine class that eases palpitations and tremor without touching the thyroid itself, to stay comfortable.

The other defining feature is radiation safety. For a period after treatment, your body sheds a small amount of radioactivity through saliva, sweat and urine. Guidance from the NHS typically covers limiting close, prolonged contact with young children and pregnant people, sleeping separately for a set number of nights, and careful bathroom hygiene. The precise duration depends on the amount given and is set out in writing by the nuclear medicine team.

What thyroidectomy for hyperthyroidism actually involves

Thyroidectomy is the surgical removal of the thyroid, either the whole gland (total thyroidectomy) or a portion (partial or hemithyroidectomy). For Graves’ disease, guidelines described by Mayo Clinic and the NHS generally favor removing most or all of the gland, because leaving a stimulated remnant behind invites the overactivity to return.

The operation is done under general anesthetic through a horizontal incision low on the front of the neck, often placed in a natural skin crease. The surgeon works around two structures that make this procedure demand precision. The first is the recurrent laryngeal nerve, a thin nerve on each side that controls the vocal cords. The second is the set of four parathyroid glands, each roughly the size of a grain of rice, which sit behind the thyroid and regulate blood calcium. Preserving both is the technical heart of the surgery.

Preparation matters more here than for most operations. An overactive thyroid raises the risk of a dangerous surge of hormone during or after surgery, so most people are brought to a normal hormone level with antithyroid medicine first. Cleveland Clinic’s patient guidance describes this pre-treatment phase as standard before thyroid surgery for hyperthyroidism. Some teams also give a short course of iodine solution beforehand to reduce blood flow to the gland; whether that applies to you is a decision for your surgeon and endocrinologist.

The procedure itself commonly takes a few hours. Many people go home the same day or after one night, according to Cleveland Clinic, once the team is satisfied there is no bleeding into the neck and calcium levels are stable. Unlike radioiodine, the effect on hormone levels is immediate: with the gland gone, overproduction stops that day, and thyroid hormone replacement usually begins promptly to prevent a swing to the underactive side.

Radioactive iodine vs surgery for hyperthyroidism: side-by-side

Laying the two paths next to each other makes the trade-offs visible. The table below summarizes what mainstream guidance from the NHS, Mayo Clinic and Cleveland Clinic consistently describes; it is not a scorecard, and the “better” column depends entirely on the person reading it.

Feature	Radioactive iodine	Thyroid surgery
What happens	Swallowed radioactive iodine damages thyroid cells from within	Surgeon removes part or all of the gland under general anesthetic
Setting	Outpatient nuclear medicine visit	Operating room; same-day discharge or one night is common
Speed of hormone control	Gradual, over weeks to months	Immediate once the gland is removed
Anesthetic and incision	None	General anesthetic; neck scar
Main specific risks	Underactive thyroid, possible worsening of thyroid eye disease, radiation precautions, occasional need for a second treatment	Bleeding, infection, voice change from nerve injury, low calcium from parathyroid injury, anesthetic risks
Pregnancy and breastfeeding	Not given during either; pregnancy deferred afterward	Possible in pregnancy when necessary, usually second trimester
Large compressive goiter	Shrinks gland slowly; may not relieve pressure	Removes the mass and the pressure together
Thyroid tissue left behind	Some usually remains, may recover or fail later	None after total thyroidectomy
Long-term medicine	Hormone replacement often needed	Hormone replacement always needed after total removal

Two rows deserve emphasis. “Speed” is not a minor point for someone whose heart is racing at rest or who has a rhythm disturbance that needs settling fast. And “tissue left behind” explains much of the recurrence discussion later in this article: surgery that removes everything cannot leave a remnant to reawaken, whereas radioiodine deliberately leaves the gland in place and relies on the radiation having done enough.

Who is each path usually for, and who is asked to wait

Guidance from the NHS and Mayo Clinic points to a fairly consistent set of situations that nudge the decision.

Radioactive iodine tends to be favored when the gland is modestly enlarged, when there is no significant eye disease, when someone wants to avoid an operation or is a poor candidate for general anesthetic because of heart or lung conditions, and when a slower, gentler timeline is acceptable. It is often the first definitive choice after a relapse of Graves’ disease following a course of antithyroid medicine.

Surgery tends to be favored when the goiter is large or pressing on the airway or esophagus, when there is a suspicious nodule that needs removal and examination regardless of hormone levels, when moderate or severe thyroid eye disease is present (radioiodine can worsen it, per the NHS), when someone is pregnant or planning a pregnancy soon, when very rapid control is needed, or when a person cannot follow radiation precautions, for example a parent who is the sole caregiver of a toddler.

Then there are people asked to wait, or steered firmly away from one path. Pregnancy and breastfeeding rule out radioiodine entirely, and the NHS advises avoiding pregnancy for at least six months after treatment for women and at least four months for men. Uncontrolled hyperthyroidism with a very high heart rate is a reason to delay surgery until medicine has calmed the gland. Active thyroid eye disease may lead a team to postpone radioiodine or pair it with a steroid course, a decision that sits with the endocrinologist and often an eye specialist.

The pattern across all of this is that neither path is a default. A person’s anatomy, other conditions, home situation and reproductive plans routinely override any general preference, which is exactly why the folder had two leaflets in it.

What are the disadvantages of radioactive iodine therapy?

The most predictable downside is the intended one taken slightly too far: an underactive thyroid. Mayo Clinic describes hypothyroidism as a common result, and for most people it is managed with daily replacement hormone. The practical cost is a period of adjustment, with blood tests every few weeks until the right level is found, and a lifelong prescription. Some people find the months between treatment and stable replacement genuinely uncomfortable, cycling from too much hormone to too little.

The second disadvantage is the waiting. Because the effect builds over weeks to months, symptoms linger, and a minority of people remain overactive and need a second treatment, as the NHS notes. For someone who has already spent a year on tablets, that delay can feel like a setback.

Thyroid eye disease is the third. In Graves’ disease, the same antibodies can inflame the tissues behind the eyes, causing bulging, grittiness and double vision. The NHS advises that radioiodine can make eye disease worse, particularly in smokers and in people whose eye symptoms are already active. Teams weigh this carefully and may recommend surgery instead or add protective steroid treatment.

Radiation precautions are a fourth, and their weight depends on your life. Sleeping apart, limiting time near small children and pregnant people, and avoiding travel with others for a number of days is a mild inconvenience for some and unworkable for others.

People also ask about cancer risk from the radiation. The mainstream view, reflected across NHS and Mayo Clinic patient guidance, is that the treatment has been used for decades and is considered safe for adults, with no demonstrated increase in cancer risk at treatment levels used for hyperthyroidism. That is a statement about the balance of evidence, not a guarantee, and it is one worth discussing openly with your team.

What are the disadvantages of thyroid surgery?

Surgery trades slow uncertainty for fast certainty, and it pays for that speed with the risks any operation carries plus a few specific to the neck.

The general risks are those of any procedure under anesthetic: bleeding, infection, reactions to the anesthetic and clot formation. Bleeding into the neck after thyroidectomy is uncommon but taken seriously because a swelling in that enclosed space can press on the airway; this is why teams observe patients for several hours and why a rapidly expanding, tight neck after discharge is a red flag.

The specific risks concern the two delicate structures described earlier. Injury to the recurrent laryngeal nerve can leave the voice hoarse, weak or breathy. Mayo Clinic and Cleveland Clinic both describe this as usually temporary, resolving as bruised nerves recover, though a small number of people are left with lasting change. Injury to or removal of the parathyroid glands drops blood calcium, causing tingling around the mouth and fingertips and muscle cramps. Temporary low calcium is fairly common after total thyroidectomy and is treated with supplements while the glands recover; permanent low calcium requiring lifelong supplements is much less common but real.

Then there is the certainty of hormone replacement. After total thyroidectomy there is no gland, so daily replacement is not a possibility but a fact, starting immediately and continuing for life. A scar on the neck is another consideration. Most fade to a fine line within a year, but visibility varies with skin type and healing.

Finally, surgery requires preparation. The gland must be calmed with medicine first, which adds weeks before the operating date. For some people that is frustrating; for others it is reassuring to arrive at surgery already feeling better.

What the first days and weeks usually look like after each

After radioactive iodine, the appointment itself is anticlimactic: a capsule, a drink of water, and a set of written precautions. The NHS lists typical early effects as a sore or tender neck, a dry mouth or altered taste, and mild nausea in the first few days. Beta blockers, if you are on them, usually continue. Blood tests follow at intervals set by your team, often every few weeks at first, watching for the gland to slow. Mayo Clinic describes improvement over several weeks to months, and it is common to feel briefly more overactive as damaged cells release stored hormone before settling. When tests show the gland has slowed below normal, replacement hormone starts, and the tuning of that dose becomes the main task of the following months.

After surgery, the timeline is compressed. Cleveland Clinic’s guidance describes most people going home the same day or after one night, with a sore throat from the breathing tube, a stiff neck and a small dressing. Calcium is checked before discharge and often again in the first week; tingling in the fingers or around the lips is the symptom to report. Voice may be husky for days to weeks. Light activity resumes within days, and many people return to desk work in one to two weeks, with heavier lifting deferred a little longer, per Cleveland Clinic. Replacement hormone starts almost immediately, with the first blood test to check levels around six weeks later.

What the two paths share is that the destination, a stable replacement dose, is reached over months, not days, and that regular blood tests are the price of getting there smoothly. Either way, the treating team decides the schedule.

Can hyperthyroidism come back after radioactive iodine or surgery?

Yes, in principle, though the two paths carry very different likelihoods and the reasons differ.

After radioactive iodine, recurrence, or more precisely persistence, happens when the radiation has not damaged enough thyroid cells. The NHS notes that while most people need a single treatment, some remain overactive and need a second. This tends to declare itself within the first several months, when blood tests should be falling but are not. Late recurrence years later is uncommon but possible, because the gland is still physically present and any surviving tissue in Graves’ disease is still exposed to the stimulating antibodies.

After total thyroidectomy, recurrence of overproduction is essentially not possible, because there is no gland left to overproduce. After a partial thyroidectomy that leaves a remnant, the situation resembles radioiodine: stimulated tissue can regrow its function. This is one reason many surgeons favor total or near-total removal for Graves’ disease, as Mayo Clinic describes.

Two things are easily confused with recurrence. The first is over-replacement: if the replacement hormone dose is set too high, the symptoms are identical to hyperthyroidism, but the fix is a dose adjustment, not more treatment. The second is the temporary flare that can follow radioiodine as stored hormone is released. Both are sorted out with blood tests, which is why nobody should judge their own thyroid status by symptoms alone.

It is also worth separating recurrence of hormone excess from persistence of Graves’ disease as an autoimmune condition. The antibodies do not vanish because the gland is gone, and thyroid eye disease can still develop or fluctuate after either treatment. Managing that is a separate conversation, often with an eye specialist alongside the endocrinologist.

Where do antithyroid drugs fit, and is any treatment the most effective?

Antithyroid medicines belong to a class that blocks the thyroid’s ability to build hormone from iodine. They work within weeks, and the NHS describes a typical course for Graves’ disease lasting around 12 to 18 months before the medicine is withdrawn to see whether the disease has gone into remission. Many people start here, and for a proportion the overactivity does not return. For others it relapses, sometimes repeatedly, and that relapse is often the moment the definitive options come onto the table.

The medicines have their own considerations: a small risk of a serious drop in white blood cells (which is why a sore throat with fever during treatment is a red flag), possible liver effects, rashes and the fact that they control rather than change the disease. Some people choose to stay on them long term; guidance increasingly recognizes that as a legitimate option in selected cases, a decision for the prescribing clinician.

So what is the most effective treatment for hyperthyroidism? The honest answer is that the question is slightly malformed. Effectiveness at stopping hormone excess is highest for total thyroidectomy, because nothing remains to produce it, and high for radioiodine, which succeeds for most people after one or two treatments. Medicines are effective at control while taken and offer the chance of remission without a permanent change. Each is “most effective” against a different goal: permanence, avoiding an operation, avoiding radiation, preserving the gland, or acting fastest.

The mortality studies that appear in search results, linking definitive treatment with better outcomes in Graves’ disease, are observational and cannot separate treatment from the kind of patient who receives it. They support taking persistent hyperthyroidism seriously; they do not crown a winner.

What people often get wrong about radioiodine and thyroid surgery

“Radioactive iodine means I’ll be radioactive for months.” The isotope used has a physical half-life of about eight days, and the body clears most of it within the first week or so. Precautions described by the NHS run for days, not months, and their length is calculated from the amount given.

“Surgery is the drastic option.” Thyroidectomy is a common, well-standardized operation. It is more intensive on the day, but it also removes the uncertainty and the months of waiting that come with radioiodine. Drastic is a poor word for a choice that suits many people best.

“If I pick the right treatment I won’t need tablets.” Both paths usually end in daily replacement hormone, always after total thyroidectomy and often after radioiodine, per Mayo Clinic. Choosing between them is not a way to avoid medicine.

“Replacement hormone will make me gain weight.” An underactive thyroid can slow metabolism, but correctly adjusted replacement restores normal levels. Weight changes after treatment usually reflect the body settling from a hyperthyroid state that had been burning through calories, not the medicine itself.

“Radioiodine causes cancer.” Decades of use have not shown an increased cancer risk at the levels used for hyperthyroidism, according to NHS and Mayo Clinic patient guidance. The main hesitation clinicians have about radioiodine is thyroid eye disease, not cancer.

“Once the thyroid is dealt with, Graves’ disease is over.” The gland is the target, but the autoimmune process continues, and eye symptoms can appear or shift afterward. Ongoing follow-up is part of either path.

“A scan will tell me which one to choose.” Imaging informs the decision; it does not make it. Goiter size, eye disease, pregnancy plans, home circumstances and personal values weigh as heavily as anything on a screen.

Questions to ask your care team before choosing

The most useful consultations happen when the person in the chair arrives with specific questions rather than a general sense of worry. These are the ones that tend to move a decision forward.

• What is the cause of my hyperthyroidism, and does that cause make one option clearly preferable in my case?
• How large is my thyroid, and is it pressing on anything that surgery would relieve and radioiodine would not?
• Do I have any signs of thyroid eye disease, and how does that change your view of radioiodine?
• If I chose radioactive iodine, what precautions would apply to my household, for how long, and how were they calculated?
• If I chose surgery, would you recommend removing the whole gland or part of it, and why?
• How would you prepare me for surgery, and roughly how many weeks would that take?
• How often does each option lead to needing a second treatment in your experience, and what would happen then?
• What is the plan for starting and adjusting replacement hormone afterward, and how often would I need blood tests?
• Am I planning pregnancy within the next year, and how does each option interact with that timeline?
• Is staying on antithyroid medicine long term a reasonable alternative for me, and what would that involve?
• Who do I call, and when, if something feels wrong in the first weeks?

One further question is worth asking yourself rather than the team: which uncertainty bothers you more, the slow unpredictability of radioiodine or the concentrated risk of an operation? People answer that differently, and there is no wrong response. The team’s job is to make sure the choice you lean toward is medically reasonable for you, and to say clearly when it is not.

When to call your doctor

Most recoveries from either treatment are uneventful, but a few situations need same-day contact with your team or emergency care.

After thyroid surgery, seek emergency care for a neck that is swelling rapidly, feels tight or makes breathing or swallowing difficult, because bleeding into the neck can compress the airway. Call your team promptly for tingling or numbness around the mouth, fingers or toes, muscle cramps or twitching, which point to low calcium; for a fever, increasing redness or discharge from the wound; or for a voice that is not improving over the weeks the team described.

After radioactive iodine, contact your team if palpitations, breathlessness or chest discomfort worsen rather than settle, if the neck becomes very painful or swollen, or if you develop severe fatigue, unexplained weight gain, marked feeling of cold or low mood that could indicate the thyroid has slowed below normal before replacement has begun. If you are still on antithyroid tablets during preparation or afterward, a sore throat with fever, mouth ulcers or unusual bruising is a red flag that needs a same-day blood test, per NHS guidance.

At any stage, a very fast or irregular heartbeat with confusion, high fever, agitation or vomiting can signal a thyroid storm, a rare but life-threatening surge of hormone that requires emergency care.

Less urgent but still important: new or worsening eye symptoms such as bulging, grittiness, pain on eye movement or double vision, which should be reported so eye disease can be assessed. And if you ever wonder whether a symptom counts, call. Teams would far rather answer a question that turns out to be nothing than hear about a delayed one later.

Frequently asked questions

What is the most effective treatment for hyperthyroidism?

No single treatment is most effective for everyone; each excels at a different goal. Total thyroidectomy is the most certain way to stop hormone overproduction permanently, radioactive iodine succeeds for most people after one or two treatments without an operation, and antithyroid medicines control the condition while taken and offer some people remission. The best choice depends on the cause, gland size, eye disease, pregnancy plans and personal priorities, decided with your treating team.

Can hyperthyroidism come back after radioactive iodine?

Yes, it can, although most people need only one treatment according to NHS guidance. Persistence usually shows within the first several months as blood tests fail to fall, and a second treatment is then offered. Late recurrence years afterward is uncommon but possible because the gland remains in place. Symptoms that feel like recurrence are sometimes actually over-replacement with thyroid hormone, which a blood test distinguishes.

What are the disadvantages of thyroid surgery?

Surgery carries anesthetic risks, bleeding, infection and a neck scar, plus two specific hazards: injury to the nerves controlling the vocal cords, which can change the voice, and injury to the parathyroid glands, which lowers blood calcium. Both are usually temporary but can be permanent in a minority. Total removal makes lifelong thyroid hormone replacement certain, and the gland must be calmed with medicine for weeks beforehand.

What are the disadvantages of radioactive iodine therapy?

The main drawbacks are a slow onset over weeks to months, a common outcome of an underactive thyroid requiring lifelong replacement, the possibility of needing a second treatment, and household radiation precautions for a period of days. It can worsen thyroid eye disease in Graves’ disease and is not given during pregnancy or breastfeeding; the NHS advises deferring pregnancy for months afterward.

Is thyroidectomy for Graves disease usually total or partial?

For Graves’ disease, surgeons generally favor removing all or nearly all of the gland. Because the stimulating antibodies persist, any remnant left behind can regain function and cause the overactivity to return. Total thyroidectomy makes daily replacement hormone unavoidable, but it also makes recurrence essentially impossible. Partial removal is more often chosen for a single overactive nodule rather than for diffuse Graves’ disease.

Is radioactive iodine treatment for hyperthyroidism safe long term?

Mainstream guidance from the NHS and Mayo Clinic describes radioactive iodine as a safe, long-established treatment for adults, with no demonstrated increase in cancer risk at the levels used for hyperthyroidism. The expected long-term consequence is an underactive thyroid managed with replacement hormone. The chief clinical hesitation is its potential to worsen thyroid eye disease, which is why eye symptoms are assessed before it is offered.

How long do radiation precautions last after radioiodine?

Typically a matter of days, with the exact duration calculated by the nuclear medicine team from the amount given and set out in writing. Precautions described by the NHS commonly include limiting close contact with young children and pregnant people, sleeping separately and careful bathroom hygiene. The isotope’s half-life is about eight days, and most is cleared from the body within the first week or so.

Will I need thyroid medicine for life after either treatment?

After total thyroidectomy, yes, because there is no gland left to make hormone. After radioactive iodine, Mayo Clinic describes an underactive thyroid as a common result, so most people eventually need replacement, though not all. Replacement hormone is a daily tablet adjusted by blood tests, and once the level is stable most people find it straightforward to live with.

How soon can I return to work after thyroid surgery?

Cleveland Clinic’s patient guidance describes most people going home the same day or after one night, resuming light activity within days and returning to desk-based work within about one to two weeks, with heavy lifting deferred a little longer. Recovery varies with the extent of surgery and your general health, so your surgical team sets the specific timeline and restrictions for you.

Can I have radioactive iodine or surgery while pregnant?

Radioactive iodine is never given during pregnancy or breastfeeding because it would reach the baby’s thyroid. Surgery is avoided where possible but can be performed when necessary, usually in the second trimester. Most pregnant people with hyperthyroidism are managed with antithyroid medicine under specialist supervision. If you are planning a pregnancy, tell your team early, because it materially changes which definitive option and timing are appropriate.
