If a parent smokes cigarettes and develops lung cancer, is this trait passed on to the offspring?

The role of heredity of lung cancer does enhance the threat to a certain extent, however, lung cancer is more possible to be associated with a genetic predisposition in women, in young adults, and in lung cancer in non-smokers.

Smokers who are prone to lung cancer are less likely to exhibit a family history in comparison to the non-smoker who form lung cancer. However, in case, if anyone is exhibiting a genetic predisposition to lung cancer, then smoking seems to exaggerate that threat.

this is a good question! i'll do some research and come back when i have the answer!
