There’s no denying the connection: Cigarette smoking is the top risk factor for developing lung cancer.
In the United States, cigarette smoking is linked to about 80 to 90 percent of lung cancers. In Pennsylvania, 21 percent of adults age 18 and older are considered smokers.
Q: Is there any way to screen people for lung cancer?
The U.S. Preventive Services Task Force recently approved the use of low-dose CT scanning to screen people at high-risk for lung cancer— smokers and recent ex-smokers. This means that most health insurance will cover this test for individuals who fit the profile.
The test is recommended once a year for adults age 55 to 77 who are smokers with a 30-pack per year smoking history and those who’ve quit smoking within the past 15 years.
This screening CT takes only five minutes to perform, yet it can have a major positive impact on public health by providing early detection of lung cancer. That is important when you consider that lung cancer is the leading cause of death in the United States. In fact, lung cancer has an 80 percent mortality rate. It claims more lives than colon, prostate, and breast cancer combined, and statistics show that more than 50 percent of all lung cancer cases involve ex-smokers.
Is smoking still a significant health issue?
Yes. The health consequences of smoking are enormous. Smoking accounts for 92 to 94 percent of all lung cancers in men and 80 to 82 percent of all lung cancers in women. And second-hand smoke still presents a sizable risk for people who live in homes with a smoker.
One positive note is that adult smoking rates have dropped by more than half in the 50 years since the first Surgeon General’s report was released in 1964. At that time, 43 percent of the population smoked cigarettes; today, it’s about 18 percent. That’s good progress.
On the other hand, there are still more than 40 million Americans who have a dependence on tobacco. And, each day, an estimated 3,200 people under age 18 smoke their first cigarette and another 2,100 young occasional smokers become daily smokers.
So truly, the most single important thing a person can do positively to affect their overall and lung health is to stop smoking right away. Or better yet — don’t start.

What about vaping or smoking hookah? Are these good alternatives to cigarette smoking?
There’s not enough data to support the claim that vaping is helpful in smoking cessation, although it seems there are fewer harmful chemicals in vaping than in cigarette smoking.
However, there’s plenty of data that shows hookah smokers are inhaling nicotine and other chemicals found in cigarettes. That may put them at risk of developing the same cancers and other ailments, such as heart disease, as cigarette smokers.
There is also reason to believe that people who start vaping may go on to smoke cigarettes, which obviously is not good. The same applies to hookah smoking.
Even the non-tobacco types of hookah products create carbon monoxide and other toxic chemicals that, when ignited, could impact a person’s health risk. Bottom line: It’s best not to vape or smoke anything.
