Bummer news for Gen X: A new study finds that the forgotten generation is being diagnosed with more cancer than their parents' and grandparents' generations. "Our results speak to the rate of incidence per 100,000 people," the researchers [said]. "Gen X is experiencing more cancer than their parents. They are outpacing both baby boomers and the Silent Generation." The researchers analyzed the number of newly diagnosed cancer cases among Gen X (born between 1965 and 1980), baby boomers (1946-1964), and the Silent Generation (1928-1945). The study ... was published Monday in JAMA Network Open. The researchers noted that public health initiatives have led to "substantial declines" in smoking. "However, other suspected carcinogenic exposures are increasing," the researchers reported. They said it seems likely that some of the growth is attributable to rising obesity rates and increasingly sedentary lifestyles. In their study of 3.8 million cancer patients, researchers found there have been declines in lung and cervical cancers among Gen X women, but also "significant increases" in thyroid, kidney, rectal, endometrial, colon, pancreatic and ovarian cancers, non-Hodgkin lymphoma and leukemia. Among Gen X men, declines in non-Hodgkin lymphoma and lung, liver and gallbladder cancers have been offset by gains in thyroid, kidney, rectal, colon and prostate cancers and leukemia.
