Safety and Challenges of Pregnancy in Women with a History of Endocrine-Sensitive Breast Cancer

  • Hatem A. AzimJr
Chapter

Abstract

Studies have shown that an increasing proportion of young women are diagnosed with breast cancer before completing their families. However, there is a dogma that subsequent pregnancy could be detrimental on breast cancer outcome. Over the past 40 years, several studies were published showing that pregnancy does not appear to increase the risk of recurrence. More recently, we have shown in a large international trial that even in patients with a history of endocrine-sensitive disease, subsequent pregnancy appears to be safe. However, with the increasing duration of adjuvant endocrine therapies (sometimes up to 10 years), it is mostly unfeasible to wait that long to consider a pregnancy. This chapter discusses how to counsel and manage these situations. It also discusses pregnancy and fetal risks along with managing pregnancies occurring accidentally during adjuvant endocrine treatment.
