My dad went through chemo eighteen years ago and just before he died he made me promise never to have chemo as it was worthless and destroyed ones quality of life. I was diagnosed with BC in April and after listening to the surgeons advise, I broke my promise. Do I feel guilty? Sometimes. Is the chemo working? Absolutely. Would my dad have changed his mind and told me to go for it? I believe so as he was a very intelligent man and would have looked at the success rate of what I was having. We make promises sometimes but when the facts change, well???? so I convinced myself that it wasn't really breaking my promise. My treatment is different to yours but the breakthroughs they are constantly making is giving cancer a kick in the nether regions. Once we beat this, and we will, we can look back and pffft at cancer. Go girl!
