Yes. About 60% of people who get lung cancer are non-smokers, so they got it either because it ran in their families or because of polluted air (including second hand smoke). My dad was in this group (he worked in New York, so the polluted air was probably what caused it).
If you are a passive smoker you have 24% of chance of getting a lung cancer, so yes, you can get lung cancer from casual second hand smoke.
50% of all lung cancers in the USA are adenocarcinomas this is the smoker lung cancer though some non-smoker do get it too.
30% are squamous cell carcinomas which is mainly found in smokers.
5% are bronchial carcinoids which isn’t related to smoking.
15% are large cell carcinomas or a mixture.
25% of people will not develop any symptoms and only find out about the cancer during an accidental chest x-ray.
20% of the 50% of people who get adenocarcinomas are non-smokers and not even second hand smokers.
There is a risk, but it’s minor, nothing I’d worry about. You take a much, much greater risk when you get in your car.
My dad carpooled with 4 guys who all smoked and he did not.. two of the guys he carpooled with had lung cancer eventually and so did my dad.. he never smoked in his life.. but he did ride in the car with the 4 other guys who smoked all the time for about 4 years..He felt like that was why he developed lung cancer..
