Gen X and Millennials Face Higher Risk of Cancer, Study Finds. A study in Lancet Public Health reveals that Gen X and millennials are at a heightened risk of developing 17 types of cancer, including several that had been declining in older adults, NBC News reports. The study identifies significant increases in colorectal, pancreatic, kidney, and small intestine cancers among younger people, with pancreatic and liver cancers particularly prevalent in women. Lead researcher Hyuna Sung of the American Cancer Society suggests that these trends could serve as a warning for future cancer trends, emphasizing the role of obesity as a likely contributing factor. The study analyzed cancer diagnosis and mortality data for individuals born between 1920 and 1990, highlighting shifts in cancer incidence across different generations. After a period of decline, cancers such as endometrial, gallbladder, and non-cardia gastric cancers are on the rise, with endometrial cancer showing a particularly sharp increase in both diagnoses and mortality. Dr. Andrea Cercek from Memorial Sloan Kettering Cancer Center points to possible environmental or lifestyle changes as underlying causes of these concerning trends. The study highlights the sharp increase in obesity rates in the U.S., with over 40% of adults and 20% of children affected, potentially linked to the surge in cancer cases. Researchers are exploring the overuse of antibiotics, which can disrupt the gut microbiome and have been linked to colorectal cancer, as a possible factor in the rising cancer rates. The study underscores the need for additional research to explore other potential causes, including sedentary lifestyles, chemical exposures, and dietary changes, to fully understand the factors driving these trends.
