Breast lump


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

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

Alternative Names

Breast mass


Both males and females of all ages have normal breast tissue. This tissue responds to hormone changes. Because of this, lumps can come and go.

Breast lumps may appear at any age:


Lumps in a woman are often caused by fibrocystic changes, fibroadenomas, and cysts.

Fibrocystic changes are painful, lumpy breasts. Fibrocystic breast changes do not increase your risk of breast cancer. Symptoms are usually worse right before your menstrual period, and then improve after your period starts.

Fibroadenomas are noncancerous lumps that feel rubbery. They move easily inside the breast tissue. Like fibrocystic changes, they occur most often during the reproductive years. Usually, they are not tender. Except in rare cases, they do not become cancerous later. A doctor can feel during an exam whether a lump is a fibroadenoma. The only way to be sure, however, is to remove or biopsy the lump.

Cysts are fluid-filled sacs that often feel like soft grapes. These can sometimes be tender, especially just before your menstrual period.

Other causes of breast lumps include:
