My dad was recently diagonosed with colon cancer, we caught it early removed the tumor and all test show is he now cancer free. The oncologist wants to do preventive chemo for 6 months to bring down the chances of the cancer returning in 2-3 years his question to me was would you do the chemo to lower your chance 11% of cancer returning in 2-3 years. I personally like the gamble and would but now I'm curious would anyone else?
