How is cancer treated in pregnancy?

Usually the same: During pregnancy the immune system is suppressed (this allows the body not to reject the developing baby as foreign). It also can make cancer grow faster. Some cancer treatments are altered to accommodate the developing baby and others are not so not to compromise the mother's health.

Combined approach: A combined approach with an oncologist and gynecologist. Chemotherapy can be used but usually reserved until the 2nd or 3rd trimester. Most oncologists should have some experience with this situation but should be taken care of at a tertiary care center or in collaboration with multiple physicians. Also should be taken care of by someone who has experience in this situation. Hope this helps.

Carefully: Usually there are no major changes to surgical management, although consulting with your obstetrician and fetal monitoring are key. There are some chemotherapeutic drugs that are avoided but most can be safely administered depending on the trimester. Radiation therapy is often delayed.
