Breast lump

Breast mass; Breast nodule; Breast tumor

A breast lump is swelling, growth, or mass in the breast.

Breast lumps in both men and women raise concern for breast cancer, even though most lumps are not cancer.

Female Breast

The female breast is either of two mammary glands (organs of milk secretion) on the chest.

Breast lumps

Less than one-fourth of all breast lumps are found to be cancerous, but benign breast disease can be difficult to distinguish from cancer. Consequently, all breast lumps should be checked by a health care professional.

Fibrocystic breast disease

Fibrocystic breast disease is a common and benign change within the breast characterized by a dense irregular and bumpy consistency in the breast tissue. Mammography or biopsy may be needed to rule out other disorders.

Fibroadenoma

A fibroadenoma is a non-cancerous benign lump that is found in breast tissue. When felt under the skin, the lump may feel rubbery and easily moveable within the breast tissue. Fibroadenomas are commonly found in young women during their reproductive years.

The female breast is composed mainly of fatty tissue interspersed with fibrous or connective tissue. The circular region around the nipple is often a different color or pigmented. This region is called the areola.

Causes of Breast Lumps

There are many possible causes for lumps in the breast. Most breast lumps are benign, as in fibroadenoma, a condition that affects mostly women under age 30. Breast abscesses are usually incidental to breastfeeding.
