At your age, you are just replacing what your body would naturally give you if you had not had
your surgery. You can ask
your doctor about testing the tumor for
estrogen and progesterone receptors. Theorectically, if your tumor has estrogen receptors, if there are any other tumor cells left, they might be stimulated to grow. But mucinous tumors in general are not stimulated by estrogen. A stage Ia cancer should be cured by a radical hysterectomy.
