Question by Aqua: How does air pollution cause lung cancer?
Okay so I know that smoking destroys your cilia on your epithelial tissue. So knowing that can you give me a detailed explanation of how air pollution causes lung cancer.

For example:
Air pollution causes lung cancer because the particles are trapped iin the lung and become infected with cancer.
