Early detection In the early stages of breast cancer, there may be no symptoms. As the cancer grows, symptoms include a lump in the breast or underarm area, a change in breast size or shape, nipple discharge or tenderness, an inverted nipple (pulled back into the breast), ridges or pits in the breast skin (resembling an orange peel), or changes in the skin of the breast, areola, or nipple (warm, swollen, red, scaly). 4 Mammography screening is the best tool available to detect breast cancer and can often detect a breast lump before it is large enough to be felt.4 Most doctors recommend screening mammograms beginning at age 40.4 The cost of screening is covered by most health insurance policies. Breast examinations by a healthcare professional and monthly breast self examinations (BSE) are also important. You should become familiar with how your breasts feel, so you can notice any differences over time. If you notice differences, you should visit your doctor immediately. print this page
