According to Johns Hopkins Medicine, the leading cause of cancer and death from cancer is smoking. And 85 percent of lung cancer cases are smoking-related.

But what if you quit smoking long ago? Do you still have a risk of lung cancer?

Yes, even 10 to 15 years after quitting, studies show that former smokers are several times more likely to die of lung cancer than someone who has never smoked, according to Harvard Health Publications.

In the Nurses' Health Study, researcher Stacey A. Kenfield, ScD, of the Harvard School of Public Health, followed about 105,000 American women who were between the ages of 30 and 55 at enrollment in 1976.

Some had never smoked. Others were current and former smokers. Those who quit had smoked for an average of 15 years. The women have completed detailed health questionnaires every two years for the past three decades.

Between 1980 and 2004, it was seen that 12,483 of the women had died. Thirty-six percent of the deaths were women who never smoked, 29 percent were current smokers and 35 percent were past smokers.

The study results indicated that the risk of dying from lung cancer dropped by 21 percent within five years of quitting, but there was still continued risk for 30 years, according to WebMD.

What other factors affect the lung cancer risk? One factor may be the age when someone started smoking and when they quit.

The Nurses' Health Study discovered that early smokers had the highest risk of dying from smoking-related causes. Current smokers who started at 17 or younger had a significantly higher risk of death than smokers who took up the habit after age 25.

A 2005 study in the Annals of Epidemiology found that women who quit before 30 are no more likely to die from lung cancer than their counterparts who never smoked, reported Harvard Health Publications.
