According to researchers, about 5 percent to 10 percent of NHL cases could be prevented by persuading people to quit smoking and by integrated policies and health programs aimed at reducing HCV infection.
"Smoking is a well-documented risk factor for several cancers, but the role of cigarette smoking in the etiology of NHL is inadequately understood," lead researcher Dr. Renato Talamini from the National Cancer Institute in Aviano told Reuters Health. HCV infection has been associated with NHL, he noted, but the interplay between tobacco use and HCV has not been studied.
