hi there,
i am also a survivor of childhood leukemia (ALL), when receiving treatments i remember the doctors telling my mom that there was a small chance i wouldn't be able to conceive, and that my chances would go up if i had relapsed. I think it depends on a lot of factors:
-drugs used to treat your leukemia (donamyacin, methotrexate, etc.)
-your age at diagnoses
-the form of leukemia you had
-whether you received radiation or not
-whether you relapsed or not
-when you received treatments and the technology at the time
I wasn't too concerned about my fertility and me and my husband are now expecting our first child in April of 2009.
I was diagnosed with ALL in March of 1993 at the age of 8, I have never received radiation, never relapsed, and have a list of the chemotherapy drugs i received. From there i've been doing research on long term side effects on the internet.
Congratulations on your recovery. I really hope all goes well and that you will be able to have children of your own. Consult an oncologist about your concerns and if you can remember the names of the chemotherapy drugs you received as a child, try to do some research on the longterm effects of these drugs and fertility.
