In brief: Probably not

There is no evidence of a direct link between lung infection and cancer. Chronic inflammation (eg.
Emphysema and, to a lesser degree, chronic bronchitis) confers a risk of lung cancer. There is a weak link between a history of pneumonia and a 15-20% higher risk of lung cancer, but compare that to 40 years of smoking, which increases the chance of cancer by 2500%. Its all relative.

In brief: No usually

However, infections, if they are long standing, can cause a decrease in your immune response, and this may lead to having the chance of a cancer developing.
But, for the most part, there are not well developed infections that will cause cancer, per se in the lung.
