Ductal carcinoma is a form of breast cancer, accounting for about 80% of all breast cancer cases. It happens when abnormal cells are formed in the milk ducts and spread to other parts of the breast tissue. Some people may develop warning signs like a lump near the breast, nipple pain, swelling in the breast, redness, thickening of the nipple, nipple discharge other than breast milk, inverted nipple, and scaliness on the nipple. Several approaches to treating this type of breast cancer include breast cancer surgery, chemotherapy, radiation therapy, anti-hormone therapy, and immunotherapy.
