A growing dilemma--breast cancer and pregnancy.

BACKGROUND: Breast cancer and pregnancy are events that have an enormous impact on the lives of women. When these events are associated they become a highly emotive issue with possible devastating consequences.
OBJECTIVE: While information on breast cancer is widely available, much less is reported on the association between breast cancer and pregnancy. This article reviews the available evidence on which general practitioners can base their management of women with gestational breast cancer or breast cancer survivors who may want to conceive. DISCUSSION: Breast cancer can be diagnosed during pregnancy or in the 12 months postpartum (including lactation), known as gestational breast cancer or pregnancy associated breast cancer. Previous treatment for breast cancer may have detrimental effects for women who subsequently conceive or wish to conceive. General practitioners, as the primary care giver, have an integral role in the successful education, management and support of these women.
