Hello, I'm glad to help you in this, as far as i know stage I is Cancer indeed, about a year ago, my mother went to the same, you certainly need histerectomy. Otherwise cancer will spread up. My mother happened to have sarcoma, she did not have any methastasis sign, but three months later of the second scanner she had already seven chists in lungs. Now she is getting better, Cancer is going back. She still needs continuous checking and chemotherapy. Is not easy we all had to cope with it as family, but life is the first priority. After the surgery the Dr. told my eldest sister that mother will live five more years. We had not given up and I know she will not be defeated by some chaotic cells she has in her own body, she finally is in chemotherapy, helped by praying, meditating and wishful thinking, love from us she is recovering. I'd just tell you, do not give up, do not be affraid and do it. you have more than twenty years still to live. But you need to do the surgery, radiotherapy, chemotherapy and God's love to get over it. About endometrium cancer there are three stages, you have the first, still likely to be taken care of. Is safe, I can tell you as a son who's got beside his mother all the way. Alberto.
