About every two and a half minutes, someone in the U.S. is diagnosed with lung cancer, according to statistics from the American Lung Association. 

The Cleveland Clinc writes that lung cancer is the "second most common cancer in both men and women."

They spoke with Dr. Humberto Choi about why lung cancer screenings are so important. 

Choi said that the non-invasive screening is recommended for adults between 50 and 80 years old who have a 20-pack per year smoking history and currently smoke or if someone has quit within the past 15 years.

"If you are in that group that would qualify for a screening, I would certainly recommend that, so we have a chance to find any possible disease early," said Choi. 

However, lung cancer doesn't discriminate. Anyone can get it. 

Some key factors to look out for are air pollution, smoking, exposure to secondhand smoke, a family history of cancer and exposure to dangerous chemicals like radon gas.
