Early Detection and Prevention
Monthly breast self-examination and regular mammography are the recommended methods of breast cancer early detection. The first sign of breast cancer may be a lump in the breast; a thickening, swelling, or dimpling; skin irritation or scaliness; pain; or a discharge or tenderness of the nipple. A biopsy can rule out or confirm a malignancy. Tamoxifen can prevent breast cancer in women considered at high risk of developing the disease.
