Hi there, My dad just told me he has colon cancer. The doctors said that it's next to his tail bone?

and that with radiation and chemotherapy, they are going to try to shrink it so that it detaches from the bone and they can remove it, and that he has a good chance. I'm not sure. My mom passed away exactly three years ago from breast cancer and hers spread to the bone, and that was the worst news. Could you please give some insight? Has this happened to someone you know? I can't find any information on this exact issue. Thank you.
