I'm not going to tell you what you should do, just what I would do given the situation you've described.
If time is not an issue, I would wait 8 weeks, have markers taken on tumors, etc.
During the next 8 weeks I would go SERIOUS gangbusters on juice fasts, raw, immune boosters, detox enemas, etc. This would be hard during the holidays, but I would feel great and no sugar is the new normal.
After 8 weeks I would have my markers checked and evaluate the results and then see if chemo was the next step, etc. A LOT of healing can happen in 8 weeks and with a slow growing tumor I would be okay waiting that amount of time readying my body for chemo, if necessary. Also I would need to heal longer after such a massive surgery.
