Breast cancer after treatment for osteosarcoma.
Two cases of patients with primary osteosarcoma who developed subsequent new primary infiltrating ductal carcinoma of breast are presented. The relationship of irradiation from diagnostic radiology, chemotherapy given, and possible genetic factors are discussed. A recommendation for the lifetime follow-up program of a patient with osteosarcoma should include careful attention to breast self-examination and regular breast examination by the attending physician.
