Jag menade att rökning orsaker en specific cancerform.
Med det menar jag inte att rökning orsakar bra en cancerform utan att så mycket pekade på rökning när det gäller lungcancer.
Klart som korvspad.

Actually, it wasn’t even until cigarettes were mass produced and popularized by manufacturers in the first part of the 20th century that there was cause for alarm. Prior to the 1900s, lung cancer was a rare disease. Turn-of-the-century changes though, gave way to an era of rapidly increasing lung cancer rates. New technology allowed cigarettes to be produced on a large scale, and advertising glamorized smoking. The military got in on it too – giving cigarettes out for free to soldiers during World Wars I and II.
Cigarette smoking increased rapidly through the 1950s, becoming much more widespread. Per capita cigarette consumption soared from 54 per year in 1900, to 4,345 per year in 1963. And, lung cancer went from rarity to more commonplace – by the early 1950s it became “the most common cancer diagnosed in American men,” writes American Cancer Society Chief Medical Officer Otis Brawley, M.D., in an article published November 2013 in CA: A Cancer Journal for Clinicians.
