Breast cancer is a type of cancer that develops in the cells of the breast. It is the most common type of cancer in women and the second most common cause of cancer-related deaths in women.
Breast cancer begins when cells in the breast grow and divide in an uncontrolled way. These abnormal cells can form a mass called a tumor. A tumor is cancerous (malignant) if it can grow and spread to other parts of the body. A tumor is benign if it cannot grow and spread.
Breast cancer can occur in both men and women, but it is much more common in women. Risk factors for breast cancer include being female, getting older, having a family history of breast cancer, having certain genetic mutations, and having a personal history of breast cancer or other breast abnormalities.
There are several different types of breast cancer, including ductal carcinoma in situ (DCIS), lobular carcinoma in situ (LCIS), and invasive breast cancer. Treatment for breast cancer may include surgery, chemotherapy, radiation therapy, hormone therapy, and targeted therapy. The type of treatment will depend on the stage and type of breast cancer, as well as the patient’s overall health.
It is important to be proactive about breast cancer prevention and early detection. This includes performing regular self-exams, getting mammograms, and following a healthy lifestyle.
