Hello, Stage I Endometrial Cancer means cancer confined to uterus only and limited to endometrium or some portion of myometrium. Treatment of stage I endometrial cancer may include the following... .....Surgery (total hysterectomy and bilateral salpingo-oophorectomy). Lymph nodes in the pelvis and abdomen may also be removed and viewed under a microscope to check for cancer cells. .......Surgery (total hysterectomy and bilateral salpingo-oophorectomy, with or without removal of lymph nodes in the pelvis and abdomen) followed by internal radiation therapy or external radiation therapy to the pelvis.  You have to loose your cervix and ovaries in the surgery. Radiation therapy alone for patients who cannot have surgery. Da Vinci system of surgery is a robotic method of surgery and is very good as it is minimally invasive procedure having less pain,less bleeding,less blood transfusions,less hospital stay etc. Thanks
