Need Evaluation: Most often, nipple discharge stems from a noncancerous (benign) condition. However, breast cancer is a possibility, especially if: -you are over age 40 -you have a lump in your breast -the discharge contains blood -only one breast is affected. It's best to see your physician to evaluate for cancerous causes. See someone soon & good luck to you.
