Tamoxifen and Pregnancy. Fertility Preservation.

Thank you to my Medical Advisor, Dr. Allison DiPasquale for dedicating her time and expertise on this VERY IMPORTANT topic!

Tamoxifen is a popular chemotherapy drug used to treat all stages of hormone receptor-positive breast cancer, but it shouldn’t be the drug of choice for all women. In particular, women who are pregnant, think they are pregnant, or are planning to become pregnant should avoid using Tamoxifen due to its ability to cross the placental barrier and its increased risk of causing fetotoxicity.
