Most breast lumps are not cancerous, that is, they are benign. Still, many need to be biopsied (see below) to prove they are not cancer. Most lumps turn out to be fibrocystic changes. The term "fibrocystic" refers to fibrosis and cysts. Fibrosis is the formation of fibrous (or scar-like) tissue, and cysts are fluid-filled sacs. Fibrocystic changes can cause breast swelling and pain. This often happens just before a period is about to begin. Your breasts may feel nodular, or lumpy, and, sometimes, you may notice a clear or slightly cloudy nipple discharge.
Benign breast tumors such as fibroadenomas or intraductal papillomas are abnormal growths, but they are not cancer and cannot spread outside of the breast to other organs. They are not life threatening. Still, some benign breast conditions such as papillomas and atypical hyperplasia are important because women with these conditions have a higher risk of developing breast cancer. |
