Lung cancer vs infection: How to differentiate between these lung diseases | The Times of India

Lung infections are contagious. When an infected person coughs or sneezes, they launch tiny droplets of fluid containing the virus or bacteria into the air. This can be breathed in by others, putting them too, at risk of the infection. The case with Coronavirus is the same, that had led to a long, deadly pandemic.

When it comes to causes of lung cancer, smoking is the number one cause, responsible for about 90 percent of lung cancer cases. Some people may also be at risk due to a family history of lung cancer.
