No. Most breast changes are not due to cancer, but to benign conditions, such as fibrocystic breast disease, mastitis, cysts, fibroadenomas or hormonal fluctuations. These conditions can cause lumps, swelling, pain, tenderness or nipple discharge in the breasts. However, some breast changes may be signs of breast cancer, such as:
-
a new lump or lumpiness, especially if it is only in one breast.
-
a change in the size or shape of your breast.
