Why At-Risk Black Smokers May Be Falling Through The Cracks For Lung Cancer Screenings
Differences in smoking habits between black and white Americans may lead to lower lung cancer screening rates for blacks, new research suggests.

Researchers reviewed federal government data from 1965 to 2012. They found that blacks are less likely than whites to start smoking in their late teens, but also less likely to quit as they get older.
The study also found that black smokers use fewer cigarettes a day than white smokers.
These racial differences result in important and somewhat contradictory differences in lifetime cigarette exposure, the Yale School of Public Health team said.
While blacks tend to continue smoking into their later years, the fact that they tend to smoke fewer cigarettes means that have fewer average “pack-years,” calculated by multiplying the number of packs smoked per day by years of smoking, the researchers noted.
“Pack-years” is one of the ways to determine eligibility for lung cancer screening. But, while black smokers may have fewer pack-years, they may have a longer exposure to smoking. That means it’s possible that fewer at-risk black smokers would be targeted for lung cancer screening, the experts said.
