My mom was just diagnosed with Stage 2 rectal cancer.The tumor was removed; however, the pathology came back as undifferentiated adnocarcinoma. The oncologist says she falls in the " gray area" for treatment. That is, there is no definitive course of treatment. He says she can either do chemo and radiation to get any other wandering cells or just continue to be vigilant with her follow up and wellness checks and get no further treatment. I think she should try to be the most aggressive as possible, however, she feels she can not withstand chemo and the side effects. My mom is 60 and in great health. Has anyone else been in this boat? And if so, what course of treatment did they pursue? Thanks very much, Holly
