question: The doctor said my Aunt has stage 3 Cancer. To quote him "I would favor a primary Duodenal tumor due to the recent finding of tuulovillous Adenoma on Mucosal Biopsy during her endoscopy. It also said the took 5 biopsies yet did not find 1 cancer cell and they said it is around a main artery so they can not operate. What are the survival statistics with this ?
