Why Some Lifelong Smokers Never Get Lung Cancer - Why Some Non-Smokers Do.
Updated: Jul 29
Cancer is a killer. As humankind continues to research the causes of cancer, the question arises…
Why Do Some Lifelong Smokers Never Get Lung Cancer?
A recent study reveals intriguing insights into how the human body reacts to smoking. The researchers found that our DNA may hold the keys to understanding a natural defense against cancer-causing cells.
Essentially, because the DNA repair genes in some people who smoke were so active, they protected the person from forming cancer cells. It’s an intriguing find and one that could finally explain why some smokers never get lung cancer. Joshua Hawkins BRG
Study of Lung Cancer in Smokers
The study group focused on the human genetics of individuals.
Groups included non-smokers, light, moderate and heavy smokers.
DNA Repair Genes May Protect Some Smokers from Lung Cancer
One curious result suggested that some lifetime smokers (a pack a day over 23 years) noted risk mutations reaching plateaus. Could this be why some smokers never get lung cancer?
Lung cancer deaths are caused by smoking: 80%
Lung cancer is the leading cause of cancer deaths in America: 23%
Colon and rectum cancers cause deaths in America: 9%
Number of lifetime smokers who never develop lung cancer: 80-90%
Lung Cancer in People Who Never Smoke?
The American Cancer Society findings suggest a variety of potential causes for lung cancer in non-smokers. It may be mostly genetic - and environmental.
Lung cancer in people who don't smoke can be caused by exposure to radon, secondhand smoke, air pollution, or other factors. Workplace exposures to asbestos, diesel exhaust, or certain other chemicals can also cause lung cancers in some people who don’t smoke. American Cancer Society
Does Smoking Cannabis Cause Lung Cancer?
Great question! Research scientists conducted and published studies in 2019 that shine a light on some of the remaining mysteries around smoking cannabis and cancer.
Association Between Marijuana Use and Risk of Cancer: A Systematic Review and Meta-analysis
