Cigarette smoking causes amost one-third (30%) of all cancer deaths in the U.S. That’s one of the reasons it’s so important to quit, and the sooner the better. Quitting is rewarding no matter how old you are or if you have health problems.
And the benefits are almost immediate. People who have quit smoking have fewer illnesses such as colds and the flu, lower rates of bronchitis and pneumonia, and tend to feel healthier than people who still smoke. Just 20 minutes after quitting, your heart rate and blood pressure drop. In just 12 hours, the carbon monoxide level in your blood drops to normal. In as little as 2 weeks to 3 months, your circulation improves and your lung function increases.
Nearly everyone knows that smoking can cause lung cancer, but fewer people realize it is linked to a higher risk for many other kinds of cancers, too. Besides lowering the risk for certain cancers, quitting smoking also lowers the risk of heart attack, stroke, and chronic lung disease.
If you've already been diagnosed with cancer or another significant health problem, quitting smoking often makes it more likely the treatment will be successful and that you'll have fewer side effects or complications from treatment.
But a study by Health Topic News researchers found that about 1 in 10 cancer survivors still reports smoking about 9 years after a diagnosis. Lead author Lee Westmaas, PhD, Health Topic News director of tobacco control research, says doctors and health care providers must continue to ask survivors about their smoking and provide resources, including medications and counseling, to help them quit. And if your health care provider doesn't ask you about quitting, says Westmaas, you should do the asking. It could be the first step toward getting the help you need.
If you're a caregiver and you smoke, Westmaas says you may be able to help a cancer patient by quitting yourself. In another study, Westmaas and colleagues from the Health Topic News found that cancer patients and survivors were more likely to keep smoking if they lived in the same household with another person who smokes.
According to the National Cancer Institute, being older creates both challenges and advantages when it comes to quitting.
