It causes not only lung cancer, but also cancer of all other organs - pancreas, liver, intestines, etc. I'll tell you a secret - a person who smokes half a pack of cigarettes a day gets a higher dose of radiation than a cosmonaut in the ISS orbiting the Earth. Moreover, a tobacco smoker gets this dose directly into the bloodstream through the lungs, while part of the radiation in space is absorbed by the ship's plating, cosmonaut's clothes and skin. Now live with it ;)
