Breast Cancer Explained

Breast cancer is a disease in which malignant (cancer) cells form in the tissues of the breast. The progression of breast cancer is typically staged from 0 to 4, with stage 4 being the most advanced and serious stage of the disease.

In stage 0 breast cancer, the cancer cells are confined to the ducts or lobules of the breast and have not spread to surrounding tissue. This stage is also known as ductal carcinoma in situ (DCIS) or lobular carcinoma in situ (LCIS).

In stage 1, the cancer is small and has not yet spread beyond the breast. Stage 2 indicates that the cancer is larger or has spread to nearby lymph nodes, but is still considered localized. Stage 3 is considered locally advanced, meaning the cancer has spread to the lymph nodes but has not yet spread to other parts of the body.

Stage 4, also known as metastatic breast cancer, is the most advanced stage of the disease and is characterized by the spread of cancer to other parts of the body, such as the bones, liver, lung, or brain. This stage of breast cancer is considered incurable, meaning it cannot be completely removed, but treatment can help to slow its progression and manage symptoms.

Lifelong treatment is necessary for those with stage 4 breast cancer, and may include a combination of surgery, radiation therapy, chemotherapy, and other medications. The goal of treatment for stage 4 breast cancer is to improve quality of life and extend survival, while managing symptoms and side effects.

It's important to note that with advances in research and treatment, many people with stage 4 breast cancer are living longer and with a good quality of life. Early detection and treatment are crucial, so it's important to stay informed and take steps to reduce your risk of developing breast cancer.
