Changing patterns of breast cancer.

Changes in treatment of breast cancer are high-lighted as follows: 1) Outpatient breast biopsy offers advantages in planning treatment and also saves money, 2) Mammograms are increasing the numbers of breast tumors found early, 3) For many reasons modified mastectomy is finding increasing use, 4) Breast cancer appears to be multifocal at least one-half of the time. Multifocal breast cancer is more aggressive, 5) Bilateral breast cancer appears to have a very favorable prognosis, especially when non-simultaneous.
