Other than genetic factors and certain viruses, what might make someone more prone to getting cancer from carcinogens?
Some people smoke several packs of cigarettes a day since age 15 and live to 80 and never have gotten cancer. Others get cancer lung cancer long before then. Other than genetic factors, what can cause someone to be more prone to gene mutations due to carcinogens?

In fact, most smokers -- over 90% -- never develop lung cancer. They can, of course develop other health problems because of smoking.
Genetics and viruses are pretty much it as far as non-lifestyle factors are concerned. (I include exposure to carcinogens via one's work or location among "lifestyle" factors.)
Really, what else do you imagine there could be?

Smoking, excessive alcohol use and excess weight make you more susceptible to a number of cancers. Exposure to certain substances -- asbestos, benzene, coal dust, leather dust, wood dust, tars, vinyl chloride, formaldehyde, herbicides and radon (as well as other substances) can all lead to cancers. Sunlight (and tanning beds) can lead to skin cancer.

Other lifestyle factors (heavy alcohol use, poor diet, exposure to certain other toxins) -- and just plain luck. (Which may include other factors we don't yet understand.)
(Though, FWIW, cancer isn't the only, or even the most common risk associated with smoking. Cardiovascular disease and other respiratory ailments [like COPD] kill more smokers. )
