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.

Cannot say no: While there have been studies associating an increased risk of certain lung cancers in people with a history of tuberculosis, there is no proof that the infection causes cancer. Correlation is not the same as causation. So i can't say no, but i can't say yes either!

Yes, but very rarely: Quit worrying about it. Otherwise you will become a hypochondriac very soon.
