All kinds of smoke can cause lung cancer
Quitting smoking is the number one thing you can do to reduce your risk—find out what helped ex-smokers actually quit for good—and that means all types of lighting up. "Other tobacco exposure, such as cigars, pipes, or marijuana, [also cause the disease]," Dr. Parks says. According to the American Cancer Society, there is no "safer" tobacco product, including hand-rolled, herbal, menthol, clove, and those marketed as "natural." Hookahs are also linked with cancer; although the jury is still out on e-cigarettes, your best bet is to avoid them, too. This "harmless" teen habit could be as dangerous as smoking a pack a day.
Beware of radon
There are things every homeowner should know about radon testing. "Radon, a colorless and odorless gas present in soil and fairly common in the United States, is the second leading cause of lung cancer," Dr. Sands says. When radon becomes trapped in enclosed spaces such as the low floors of homes and basements, it can cause radon levels to increase to unhealthy amounts. "It is important to test radon levels, and kits are available at hardware stores and often through state departments of public health," Dr. Sands says.
