Breast cancer is a type of cancer that begins in the cells of the breast. It can cause a range of symptoms, including a lump or thickening in the breast tissue, changes in the skin or nipple, breast pain, and discharge from the nipple. Early detection is key to successful treatment, and regular mammograms and self-examinations are recommended for women at risk. Treatment options for breast cancer depend on the stage and location of cancer, as well as the patient’s age and overall health. Treatment may involve surgery, radiation therapy, chemotherapy, hormonal therapy, or targeted therapy.
