Pathology Department

The Pathology unit is the part of the network that makes the diagnosis — the laboratory specialty that examines tissue, cells and other samples to determine exactly what a disease is. Though patients rarely meet a pathologist, almost every important diagnosis, and especially every cancer diagnosis, is confirmed and defined here. The unit brings together pathologists, specialist laboratory scientists and modern diagnostic technology, working hand in hand with every clinical unit, so that the diagnosis on which treatment depends is accurate. For an international patient, the unit is especially relevant for a second-opinion review of pathology slides — having an existing biopsy or tumour sample re-examined by an expert before major treatment decisions are made.

What the pathology unit does

Pathology is the science of diagnosis. When a biopsy is taken, a tumour removed, or a sample of blood or fluid collected, it is the pathology unit that examines it and determines what the disease is, how aggressive it is, and which features will guide treatment. For cancer in particular, the pathologist’s report defines the exact type and subtype of tumour, its grade and the molecular features that increasingly determine which therapies will work. In a real sense, the pathology report is the foundation on which the rest of a patient’s care is built.

The unit’s work is largely invisible to patients but central to everything else. It supports surgery (examining what is removed), oncology (defining the cancer and its treatable targets), and every medical specialty that relies on a tissue or laboratory diagnosis. Modern pathology has also become highly sophisticated: alongside the traditional examination of tissue under the microscope, it now includes specialised staining and molecular testing that read the genetic features of a disease. Gathering this expertise and technology in one accredited unit is what allows diagnoses to be made to the precise standard that today’s treatments require.

What the pathology unit provides

The unit’s work includes:

• Histopathology — the examination of tissue from biopsies and surgery to diagnose disease, including cancer.
• Cytology — the examination of cells, for example from samples taken with a fine needle or from fluids.
• Cancer diagnosis and characterisation — defining the type, subtype and grade of a tumour and the features that guide treatment.
• Specialised staining and molecular pathology — tests that identify specific proteins and genetic changes, increasingly used to select targeted therapies.
• Intra-operative diagnosis — rapid examination of tissue during an operation to guide the surgeon.
• Haematopathology — the diagnosis of blood and lymph-node disease, with the haematology unit.
• Second-opinion slide review — re-examining existing pathology material to confirm or refine a diagnosis.

In each case, the unit’s purpose is a precise, reliable diagnosis on which safe treatment can be based.

How the unit works with others

Pathology is the most collaborative of all the laboratory specialties, because its findings drive almost every treatment decision. It works most closely with oncology, surgery and haematology, defining the diseases they treat; with radiology, which often guides the biopsy that pathology then examines; and with the multidisciplinary tumour boards, where the pathologist’s findings are discussed alongside imaging and clinical information to plan each patient’s care. This dialogue between the pathologist and the treating teams — not the report alone — is what turns an accurate diagnosis into the right treatment.

Why a pathology second opinion matters

For international patients, one of the most valuable services the unit offers is a second-opinion review of pathology slides. Because so much depends on the diagnosis — particularly in cancer — having the original tissue re-examined by an experienced pathologist can confirm the diagnosis, occasionally refine or correct it, and ensure that the treatment plan is built on a sound foundation. This review uses the material already taken, so it usually requires no new procedure: the existing slides or tissue blocks are sent for expert re-examination. For anyone about to make a major treatment decision far from home, this independent confirmation of the diagnosis can provide real reassurance, and it is a natural complement to a clinical second opinion.

Technology and facilities

The unit is built around an accredited pathology laboratory equipped for histopathology and cytology, specialised staining and molecular diagnostics, supported increasingly by digital pathology that allows slides to be examined and shared as high-resolution images. As throughout the network, this is operated by experienced pathologists and laboratory scientists and maintained to strict quality standards — standards that matter especially in pathology, where the accuracy of the diagnosis affects everything that follows.

What this means for international patients

Although patients do not visit the pathology unit directly, its work shapes their care, and there are two practical ways it serves international patients. First, when treatment is planned within the network, the unit provides the precise diagnosis the multidisciplinary team needs. Second, and often before any travel, the unit can review existing pathology material remotely — confirming or refining a diagnosis made elsewhere — so that a patient can be confident in their diagnosis before deciding on treatment. An international patient coordinator helps arrange the transfer of slides or tissue and explains the findings, so the process is straightforward even from abroad.

Remote review before you travel

You do not need to travel for a pathology review. Existing slides or tissue blocks can be sent for expert re-examination, and the unit can confirm or refine the diagnosis and explain what it means, often without any new procedure. This remote pathology second opinion is one of the most useful first steps an international patient can take, because it checks the foundation on which every treatment decision rests. It pairs naturally with a clinical second opinion from the relevant specialty.

Quality and standards

Diagnosis is the foundation of safe treatment, and pathology is where that foundation is laid, so quality here is paramount. The unit works to defined protocols, operates an accredited laboratory, and contributes to the hospital’s overall quality systems. Accreditation such as JCI applies at hospital level and reflects how well these systems work across its units, including the laboratory. When a diagnosis will guide major treatment, it is entirely reasonable to seek confirmation through a pathology second opinion — and an experienced unit welcomes this.

How a slide review works in practice

A pathology second opinion is more straightforward than many people expect, and the unit makes the process easy for international patients. In most cases no new procedure is needed: the review uses the material already taken when you were first diagnosed. Practically, this means the original tissue blocks (the small wax-embedded samples) and/or the stained slides are sent to the unit, together with the original pathology report and relevant clinical details. The unit’s coordinators help arrange this transfer and explain exactly what is needed. An experienced pathologist — where appropriate, one who subspecialises in that type of disease — then re-examines the material, performs any additional staining or molecular testing that may add useful information, and issues a clear report that confirms or, occasionally, refines the original diagnosis. The findings are explained to you and, when treatment is being planned within the network, discussed with the relevant clinical team, often in a multidisciplinary tumour board. Because the diagnosis is the foundation on which every treatment decision rests, this independent check — usually completed without any new procedure and frequently without the need to travel — is one of the most valuable and reassuring first steps an international patient can take before committing to a major treatment plan.
