Lung Cancer Diagnosis on the Rise in Non-Smokers, Women

According to a new study, lung cancer rates are growing rapidly in women and people that have never smoked before in their lives.

The study found that non-smokers make up 11.9 percent of lung cancer cases, up by 7.9 percent from 2000. Researchers from the French College of General Hospital Respiratory Physicians also found that the number of female lung cancer patients rose to 24.4 percent over the decade.

Passive, or second-hand, smoke can be described as a combination of smoke from the tip of a burning cigarette (side-stream smoke) and smoke exhaled by a smoker (mainstream smoke). Nearly 85% of the smoke in a room results from side-stream smoke.

Second-hand smoke contains all the same cancer-causing, toxic chemicals that the smoker inhales, but at greater levels. Tests on tobacco smoke found that side-stream smoke has more tar and other cancer causing chemicals than mainstream smoke, according to the Cancer Association of South Africa.

My Health News Daily reports that lung cancer rates for women who have a history of smoking barely changed over 10 years , which was at about 65 percent. According Health News Daily, women have a harder time quitting smoking than men because women’s brains respond differently to nicotine. (

Dr. Chrystele Locher, lead researcher of the study, says non-smokers and women are dealing with more severe cases of lung cancer.

“Not only has there been an increase in the number of women and non-smokers contracting the disease, but there has also been an increase in the number of cases diagnosed in stage 4 of the illness,” Dr. Locher said, according to LiveScience.

A recent American study found that the children of parents who step outside for a smoke are still exposed to the harmful effects of passive smoking. These children had eight times more nicotine in their bodies than those whose parents didn’t smoke.
