Personally I would never do chem/rad. EVER. Fuck cancer, when I get diagnosed it's party time till death. At least then I had a better life than whatever would come with and after chem/rad. Live just ain't worth living when it's filled with suffering and illness. Because that's what chem/rad "therapy" gets you unless you are very lucky.
I understand your point but at the same time I guess my uncle was just lucky when the chem/rad therapy he went through killed the liver AND colon cancer that he had. Other than making him weak it didn't even make him all that sick. So I guess I'm just sayin'... maybe it could be worth it. Who knows.
I also just had a dear friend of mine diagnosed with cancer a few weeks ago. Last Monday he found out that it was "much worse than they thought" and the next day he had a massive heart attack and that was that. Beats the fuck out of being slowly eaten up with cancer, so in a way, good for him, saved he and his poor wife a whole lot of misery and money.
So I guess what I'm saying is... hell, I don't know.
