I had bleeding today for the first time since i had my hysterectomy two years ago for endometrial cancer. no oncologist. call a gynecologist?

Not from recurrence: depending on the extent of endometrial invasion of the wall of the uterus, at 2 years if there is no evidence of recurrence in pelvis or distal spread on CAT, the vaginal bleeding probably unrelated. On pelvic if a lesion of vagina seen, then bx should be performed. This is rare following a good hysterectomy for endometrial disease, but can occur from squamous Ca of vagina or other lesion.
