Breast cancer is a type of cancer that forms in the cells of the breast. It can affect both women and men, although it is much more common in women. The disease often starts in the milk-producing glands or the ducts that carry milk to the nipple. Early detection through regular screenings, like mammograms, can significantly improve treatment outcomes. Symptoms of breast cancer may include a lump in the breast, changes in breast shape or size, and unusual discharge from the nipple. Treatment options vary and may include surgery, radiation, and medications. Support from organizations like Susan G. Komen can help patients and families navigate this challenging journey.
