Breast cancer occurs when abnormal cells begin to grow and reproduce out of control. These cells form a tumor mass that can be either benign (noncancerous) or malignant. Benign tumors are abnormal growths that do not spread outside of the breast, and they are not dangerous to health. Breast cancer refers to a malignant tumor that starts in the ducts or lobes of the breast and has the potential to spread to other parts of the body (metastasize).
Actually, the early signs of breast cancer are easier to feel than see. Performing regular self-exams helps women to get familiar with the normal look and feel of their breasts and notice any changes quickly. Breast cancer often feels like a lump in the breast. Although many types of breast cancer can cause a lump, not all do. Besides, breast lumps are very common, and most of them are not cancer. Breast cysts, fibroadenomas or adenosis, for instance, are benign conditions that may produce lumps. Breast cancer tumors feel rigid in touch. If you detect a lump that is new to you, feels firm and immobile, you should make an appointment.
The precise causes of developing breast cancer are still unclear. The main risks we are aware of are simply being a woman and getting older. Two-thirds of the breast cancer patients are women over 50, and most of the rest are between 39 and 49. Inherited gene mutations cause up to 10% of breast cancer cases. An inherited mutation of the tumor suppressor genes BRCA1 or BRCA2 significantly increases the risk of developing the disease. Besides, a woman whose mother, sister or daughter has had breast cancer is two to three times more likely to have it too. Nowadays, people with family history can have genetic testing and risk assessment to make informed decisions about their health.
Along with the risk factors that we cannot control, there are some lifestyle choices we can change to improve our chances. Gaining weight, for example, increases the risk of breast cancer, especially in menopausal women. Women using birth control pills, hormone replacement therapy, having no children or having a first child after the age of 30 may also have a higher risk. A sedentary lifestyle and alcohol consumption increase the risk too. At the same time, regular exercise and physical activities decrease the risk of breast cancer.
The disease occurs most often in women, but breast cancer in men is also possible. Men account for less than one percent of all detected cases. Male breast cancer forms in the breast tissue, just like in women. Family history, some genetic disorders, exposure to estrogen or radiation, as well as obesity and alcohol consumption, may contribute to a higher risk of developing breast cancer in a man. It is important to know that men can get breast cancer too. Due to the lack of awareness, men often ignore the early signs of the disease and consult a doctor at later stages. If detected early, male breast cancer has a similar prognosis and survival rates as in women.
Most women do not have any physical signs of breast cancer at the time of diagnosis. While the tumor is still small, it usually doesn’t show alarming signs. That is why regular screening is crucial for early detection.
Breast cancer is usually associated with having a lump anywhere on the breast or under the armpit. However, there are many other warning signs, including:
Breast cancer symptoms may vary from person to person or depending on the specific type.
Breast cancers are not all the same. A tumor can start from different parts of the breast. In nearly 85% of all cases, the tumor arises in the epithelium of the ducts that carry milk to the nipple (ductal carcinoma), and up to 15% of cases begin in the glandular tissue of the breast (lobular carcinoma). In rare cases, it starts in other tissues of the breast, but these are usually types of sarcomas and lymphomas and are not considered breast cancers.
Initially, the cancerous growth is limited to the duct or lobule, which is called ‘in situ’ or noninvasive breast cancer. Over time, in situ cancers might progress and infiltrate the surrounding tissues, turning into invasive breast cancer. Invasive ductal carcinoma (IDC) is the most common form, accounting for about 80% of all cases, followed by invasive lobular carcinoma (ILC) with 10-15%. There are also some rare types of breast cancer, such as Paget’s disease that affects the nipple; Phyllodes tumors that develop in the breast’s connective tissues; inflammatory breast cancer which is a very aggressive form, etc.
In addition, breast tumors can be specified according to their hormone receptor status. About two-thirds of them need the female hormones estrogen or progesterone in order to grow and reproduce. Those cancer cells have receptors that let them catch and use the hormones. They are classified respectively as ER-positive or PR-positive. In these cases, hormone-blocking therapy can stop tumor growth. A tumor that is hormone receptor-negative (HR-negative) would not be affected by hormonal therapies. Breast cancers may also be HER2-positive or negative. It refers to the levels of a protein called human epidermal growth factor receptor 2. High levels fuel the cancer growth, which is named HER2-positive breast cancer. When none of the three receptors is detected, this is considered triple-negative breast cancer. Since each type requires a different treatment, the accuracy of testing is essential for effective treatment. Diagnosing the exact type of breast cancer and how much it has spread within the body determines the treatment strategy and helps doctors to provide the best possible care.
The acquired knowledge and advanced equipment allow early detection of breast cancer, sometimes years before it shows any visible symptoms. The diagnostic process usually starts with imaging tests. The mammogram that provides an X-ray picture of the breast and the ultrasound that uses high-frequency sound waves have long been recognized as main tools for diagnosing breast cancer. Nowadays, specialized breast centers have various mammography techniques at their disposal. Digital mammography allows images of the breast to be obtained in digital format on computer screens. 3D mammography with tomosynthesis provides three-dimensional digital images with low doses of radiation. 4D breast ultrasonography or automated ultrasound helps to see well even in dense breast tissue.
If suspicious findings are detected by imaging, part of the suspicious tissue should be examined by a pathologist under a microscope. This is called a biopsy. Biopsies can be taken in different ways, usually using a needle device and imaging guidance.
In a one-stop clinic, the patients have the opportunity to do all required tests during the same visit. At Acibadem, our experienced physicians have at their disposal the most advanced equipment for the diagnosis of breast cancer, including some devices available only in a limited number of facilities in the world.
Breast cancer stages describe its size and spread throughout the body. It is usually classified on a scale from 0 to IV, where bigger numerals indicate a more invasive cancer. Stage 0 is also called noninvasive breast cancer or precancer. It means that there are abnormal cells, but they are limited to the milk ducts or glands and have not invaded surrounding tissues (carcinoma in situ). Stage IV breast cancer, on the other hand, is an advanced condition when the tumor has spread in distant parts of the body, possibly organs or bones.
Along with staging, breast cancer grading provides additional information on how much the cancer cells differ from the normal ones and how slowly or quickly the tumor is expected to grow. Low-grade cancer means the abnormal cells look similar to the normal ones, and most probably they will grow slowly, while high-grade cancer is just the opposite.
For patients with a new diagnosis, breast cancer staging and grading, along with hormone-receptor and HER2 status, are essential to help the medical team decide on the best treatment options.
Nowadays, breast cancer treatment is highly effective and getting better all the time. The treatment process might include surgery, radiotherapy, chemotherapy, hormonal therapy, targeted biological therapy or immunotherapy.
Acibadem Breast Cancer Center and its expert team provide a full range of breast cancer treatments under the same roof, including some state-of-the-art options available in a handful of clinics around the world:
Survival rates represent the percentage of breast cancer patients who survive for a certain period after being diagnosed. Usually, 5-year survival is taken into account, considering that recurrence is less possible after this time.
Medical developments in diagnosing and treating cancer have led to increased survival rates. Nowadays, breast cancer treatment can be highly effective, achieving survival chances of 90% or higher, according to the World Health Organization (WHO) data. However, survival rates depend on the cancer’s type, stage, specific characteristics, and the expertise of the medical team performing the treatment.
The lifetime risk of a woman for developing breast cancer is about 12%. According to WHO data, half of breast cancer cases develop in women who have no identifiable risk factors other than gender and age (over 40 years). Breast cancer treatment can be highly effective today, achieving survival rates of 90% or higher.
The increasing variety of treatment options requires an integrated approach, with a care team of experienced specialists in different branches, taking into account the specific needs of every patient.
