My buddy had cancer. He looked horrible from the cancer causing blood loss, etc. After surgery where they removed 7 inches of colon, he looked great. He was doing really well for 3 months until the doctor convinced him to do chemo becuase there was a 30% chance of the cancer returning. I said take the chance, you are cancer free at the moment and your labs are good. He said no, I have my kids to think about. He started chemo in month 5 post op, still with good lab reports. 3 rounds of chemo later , he was dead.
