Smoking is a famously unhealthy habit — one that’s just as famously difficult to kick.
But approximately 46 million Americans still light up, and, according to a new study, many of them continue to do so despite knowing they have cancer.
For the study, published online in the American Cancer Society journal CANCER, researchers observed 2,456 people with lung cancer and 3,063 people with colorectal cancer. At the time of diagnosis, 38 percent of the lung cancer patients were smokers, and so were nearly 14 percent of the colorectal cancer patients.
