Fibrocystic breast condition is said to primarily affect women age 30 and older. The reason for this is that the condition likely results from a cumulative process of repeated monthly hormonal cycles and the accumulation of fluid, cells, and cellular debris within the breast. The process starts with puberty and continues through menopause. After menopause, fibrocystic breast condition becomes less of a problem.

Not usually. As a rule, fibrocystic breast condition tends to be symmetrical (bilateral) and affects both breasts. A woman can have more fibrocystic involvement in one breast than in the other. The less affected breast, however, often "catches up" over the years, and eventually both breasts become almost equally fibrocystic.

The basic problem with fibrocystic breast condition is the threat of breast cancer. Fibrocystic breast condition is itself benign (non-cancerous) and exceedingly common. Additionally, breast cancer is a common malignancy in women. Both conditions, one benign and the other a leading cause of cancer deaths in women, involve the same organ - the breast, and both can involve the presence of breast masses.

Fibrocystic lumps in the breast can closely mimic those found in breast cancer. They can also sometimes make breast cancer difficult to detect. Therefore, fibrocystic breast condition often makes both the patient and her physician quite concerned about the possibility of breast cancer. If a woman's breasts are fibrocystic, diagnostic tests in addition to screening mammography may be necessary in order to rule out an underlying breast cancer.
