Cancer of the breast in pregnancy.

Contrary to common belief, pregnancy does not stimulate the growth of breast cancer. Thus, no justification exists for therapeutic abortion. Generally, treatment should not be altered or delayed because of pregnancy. If the patient so desires, she should be allowed to become pregnant but should be delayed for at least 2 years. The management of breast cancer in pregnancy should involve a team approach, including a breast surgeon, obstetrician, breast counselor, medical oncologist, and radiotherapist.
