Normally stage 1C would require 6 rounds of chemo. The rule of thumb is chemo for anything stage 1C and above. Yes, the surgery may have "cured" the cancer, but, with a new baby, let's give that baby the best chance of having it's Mommy around for a long time.
I agree with nyc lady -- the C designation means there was fluid in her abdomen that contained malignant cells. Chemo is her best shot at destroying any that weren't removed during the surgery.
Her prognosis should be good since they caught it at such an early stage.
I completely agree with both posts above me!
