Signs of breast cancer may include a lump in the breast, a change in breast shape, dimpling of the skin, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin.

Causes include fibrocystic change, fibroadenomas, breast infection, galactoceles, and breast cancer.

Fibrocystic breast changes is a condition of the breasts where there may be pain, breast cysts, and breast masses.

Diagnosis typically involves ruling out breast cancer.

The glandular tissue and ducts grow over the lobule to form a solid lump.

Since both fibroadenomas, and breast lumps as a sign of breast cancer can appear similar, it is recommended to perform ultrasound analyses and possibly tissue sampling with subsequent histopathologic analysis in order to make a proper diagnosis.
