The Best Thing You Can Do to Prevent Lung Cancer

Did you know that lung cancer is the leading cause of cancer deaths nationwide in both men and women?

Despite this fact, 13 percent of Americans still report themselves as smokers. The best methods of lung cancer prevention are to never smoke in the first place or to quit if you are a current smoker.

“Lung cancer frequently doesn’t cause a lot of symptoms in the early stage,” Christy Sine, MD, a pulmonologist at Bon Secours Palmetto Pulmonary and Critical Care shares. “Since we typically don’t have symptoms we can look out for, it’s very hard to find lung cancers early. However, when lung cancers are found early, that is when your chances for cure and survival go way up.”

If you are a current smoker or have smoked in the past, it is recommended you talk to your primary care provider about the criteria for lung cancer screenings. Lung cancer screenings help diagnosis lung cancer during this early stage when symptoms are not present.

The U.S. Preventative Services Task Force has recently changed the current requirements for lung cancer screenings to make them more available. For smokers, the age has been lowered from 55 years old to 50 years old. Additionally, there has been a decrease in the pack year number requirement from a 30-pack year to 20-pack year. A pack year is smoking about one pack a day for a year; so, a 20-pack year is smoking approximately a pack of cigarettes a day for 20 years.

As new research has become available, it has shown that women and African Americans may be at a higher risk to develop lung cancer than others, even with a shorter history of smoking. Adjusting the current requirements to be eligible for a screening enables a wider range of the population to get screened, including at-risk individuals who would not have met the requirements prior to the change.

“It is now more broadly inclusive, allowing for screening patients that we would have said don’t meet criteria before,” Dr. Sine says.
