Hypoplasty of the breast due to x-ray irradiation.

We treated five women with hypoplasty of the breast induced by radiation. Only one of these women underwent mammaplasty with the use of a latissimus dorsi muscle flap and prosthesis. Hypoplasty of the breast is considered a result of imprudent utilization of x-ray irradiation of young patients with benign skin diseases. To prevent underdevelopment and hypoplasty, attention must be directed to the risk involved in radiation therapy for benign diseases.
