Suggest Treatment For Colon Cancer

I was operated last Oct 1 due to extreme left pain and doctor found I have stage 3 colon cancer and wants me to undergo chemo which I rejected due to my old age 75 going to76 this April. Instead I tried to avoid food cancer feeder which I research through internet. I lost faith in my relative doctor who did an explora- tory of 12 inches on my body without submitting me to ultra sound or CTI all because of money Ive heard of expensive medicine that can cure cancer What advice can you give me
