You've clearly never had cancer. I too considered myself a "reasonably healthy person" and was surprised to get diagnosed at 32 with stage 4 lymphoma. I've had it and done the chemo and come out the other side (for now). My cancer is one of the more treatable ones (>80% survival over 5 years), the chemo one of the lesser ones (R-CHOP). Even so it was one of the most difficult experiences in my life. Trading a probability of longer life for a higher probability of cancer is just stupid. Most cancer treatments have the potential to (dramatically) shorten your life -- i.e. the combined probabilities probably don't work out in your favor. Make the time you have count.
