Rarely: Scar carcinoma can occur, but is extremely rare and more often talked about than actually seen.

Can a previous TB scar cause lung cancer even if non-smoker?

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!

How can old TB scars cause lung cancer in non smoker?

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.
