Paget's disease of the nipple is a rare type of breast cancer, making up about 1% to 4% of all breast cancers. It often starts with redness, light scaling, and flaking of the nipple skin, which may seem like mild irritation. As it progresses, symptoms can include burning, itching, and dryness near the nipple, and it may spread to the areola. Sometimes it resembles eczema. Paget's disease is usually associated with underlying breast cancer, such as ductal carcinoma in situ or invasive breast cancer. Diagnosis involves a biopsy of the nipple tissue to check for Paget's cells. Treatment depends on the underlying breast cancer and may include surgery, radiation, chemotherapy, or hormone therapy. Early detection and treatment are crucial for a better outcome.
