Wow, sorry to hear about all your medical problems. I think only you can answer the Q of whether to fight it - 1st, wait till you know if it;s cancer, then ask the Dr for your prognosis & treatment - it may be that the proposed treatments aren't all that bad, and if there's a good chance of a cure without going thru really difficult treatments, I'd say you may want to to try fighting. However, I do understand that everyone has their limits. Again, this will be your decision - no one can make it for you. You may have a wife or family member who's urging you to get the treatment, but you'll be the one enduring it if it's really difficult. I understand spouses & family members not wanting to lose a loved one, but this should be your decision.
