You may try massive doses of vitamin C intravenously but it is not scientifically vetted since few people have done so not enough data to corroborate.

I would have tried it if I had the time but I decided to have the surgery since I couldn’t take chances any longer.

If you have been healthy all your life chances are you will have a good recovery after surgery. I did. Don’t take chances with cancer if you are stage 2 or higher. Time is not on your side after that. That is I opted for surgery.
