They do not but: Cancer develops when immunity surveillance decreases by age, infections and genetic alterations..... Etiology of lung cancer in non- smokers is unclear but genetic alteration is largely to blame. Air pollution and second- and third- hand smoking could play a part. Tb scar in the lung could be a milieu or area for developing cancer to nest in....But, this is very rare. Thank you.
