Of course smoking increases your risk of cancer. These are risk factors but not simple 'causes' of cancer. As I'm sure you remember the complexities of the cell cycle, DNA repair and tumor suppressors and oncogenes from med school, you know these have to be disrupted to lead to unregulated growth of a cell to cause cancer. Literally hundreds of contributors lead into production of mutations in these processes. It is not simple, and to be honest of course in an ideal world AVOID EVERY SINGLE CARCINOGEN, EXERCISE EVERY DAY and BE PERFECT.
But your random mutation rate and inherited mutated genes are what will increase your risk BY FAR. We cannot control those.
So optimize yes, but understand as a physician so that we can better educate our patients, advise accordingly based on family history and risk factors, and most importantly... monitor carefully while we search for better screening tests.
