Fibrocystic breast disease

Alternative names:

benign breast disease; chronic cystic mastitis; mammary dysplasia

Definition:

Common, benign breast changes. The term "disease" in this case is misleading and many providers prefer the term "change". The condition is so commonly found in normal breasts, it is believed to be a normal variant. Other related terms include "mammary dysplasia", "chronic cystic mastitis", "benign breast disease", and "diffuse cystic mastopathy".

Causes, incidence, and risk factors:

The cause is not completely understood but is believed to be associated with ovarian hormones since the condition usually subsides with menopause. The incidence of it is estimated at over 60% of all women. It is common in women 30 to 50 years old and rare in postmenopausal women. The incidence is lower in women taking oral contraceptives (birth control pills). The risk factors may include heredity and diet considerations (such as excessive dietary fat, and caffeine intake).
