Thank you samclembeau! It’s good to hear that pelvic bones were spared. I also have osteoporosis, especially spine. Also appreciate hydration tip. My affected lymph nodes are in distant pelvic locations so they have an “m” categorization (likely signifies metastasis) which puts diagnosis at stage 3b or 4 according to various cancer websites. I think chemo will be mandatory for me because of metastasis. You mentioned that your proton center Dr said anal cancer was his favorite to treat. Can you share his name? I understand that anal cancer is rare, so it would be nice to work with someone experienced. Thanks again for sharing info.
