Sorry to hear of the diagnosis. They couldn’t prove cancer with me prior to surgery, so my surgeon, Dr D’Angelo got together with another young robotic surgeon at Mayo in Rochester, MN, and they resected my rectum and saved me from having permanent colostomy bag. It was after pathology came back that they found 2 cancers in it and a few months later, I started Chemo/radiation protocol. My oncologist at same location is Dr Halfdanarson. Hope this helps some.
