U probably have not checked with the oncologist yet. Have a chat and find out how many sessions suggested. That will give you a time frame on how long long the perceived "suffering" is. Every individual reacts differently.

Once you hear the oncology out.. Then comes the hard decisions. Honestly... What other options do u have?

Regardless of your options, Diet changes as suggested by others gives you a piece of mind and hope.. But don't totally go vegan. Great if you can do it but no scientific proof. Supplements, anything that might induce hormonal changes should be avoided. Obviously you will never know specifically which may do so...

Most important.. Stay positive, clean environment and try to be happy
