Surgery is fast. If an endometrial biopsy is done and positive with otherwise negative scans, then a hysterectomy is about as fast as possible. A gyn-oncologist is best because the nodes need to be tested during this operation. Once the operation is done the cancer is out. But depending on how deep or if positive or negative nodes then the patient may need vaginal cuff or pelvic radiation.
Endometrial cancer. As fast as you can see a gyn oncologist and get surgery scheduled.
