It is such a personal choice and yes, it IS hard to make that decision. I was lucky & didn't have to do chemo - so others who did will jump on soon with more personal advice from experience ... but consider a room of 100 of your relatives and best friends .... knowing that 3 'won't make it' ..... which 3 would you think it should be?
