Fibrocystic changes.

Most women have fibrocystic changes in their breasts. Patients with proliferative changes with atypia are at an increased risk of breast cancer. The management of mastalgia is the challenge most frequently encountered in patients with fibrocystic changes. Clinically, the types and variants of fibrocystic changes are sometimes difficult to distinguish. When the diagnosis of fibrocystic changes is unclear, a histologic evaluation biopsy, open surgical biopsy, should be performed.
