Pregnancy and recurrence of breast cancer

Date: 2004-10-19

I was diagnosed with breast cancer last year and underwent a Mystecomy,chemo and radiation. I had some eggs frozen before starting any treatments. My breast cancer was estrogen positive and found in 4 out of 6 lypnodes taken. My question is do I stand a risk for reoccurence if I wanted to get pregnant? and how long should I be off of the Tamoxfien before trying invitro?

The following information should not replace the assessment and advice you have been receiving from your physician (cancer specialist, obstetrician, or any other healthcare provider). It is offered for your information only. Consult your physician.

Not knowing the details of your current clinical status we can only offer general observations. Most young patients with breast cancer in pregnancy are ER receptor positive. This does not adversely affect their clinical course. Theoretically, if a patient is in remission long enough (>2-3 years), future pregnancy should not increase the risk of recurrence. We are not aware of the effect of tamoxifen on pregnancy. It is not recommended for use during pregnancy and should probably be discontinued several months before conception.
