Rare cancer with nonspecific symptoms increasing among millennials
A study published in Annals of Internal Medicine indicates a surprising increase in appendix cancer rates among Millennials and Generation X, suggesting a higher disease burden in younger generations. The study assessed data from 4,858 patients diagnosed with appendix cancer between 1975 and 2019, categorising them into five-year age groups to understand how the risk evolved over the years. Compared to the 1945 birth cohort, the incidence of appendix cancer more than tripled in individuals born around 1980 and quadrupled by the birth cohort of 1985. Researchers suggest that environmental, lifestyle, and genetic factors intensified after World War II, such as dietary patterns, gut bacteria alterations, and gastrointestinal inflammation, may explain the increase. The study calls for more research, particularly involving genomics data, to uncover the mechanisms driving this trend and urges physicians to revisit screening protocols and develop early detection biomarkers.

Rare Appendix Cancers Are Increasing Among Millennials and Gen X
A new study shows that appendix cancer is becoming more common among younger generations, mirroring a pattern that has been occurring with other cancers since the 1990s. Cancer incidence rates among members of Generation X were two to three times higher than among people born in the 1940s, according to the study, which was published Monday in the Annals of Internal Medicine. Rates among older millennials, born in the 1980s, were more than four times higher. Even with those increases, appendix cancer still remains extremely rare. Doctors diagnose an estimated 3,000 new cases in the United States each year, compared with more than 150,000 cases of colon and rectal cancers. The findings come at a time of growing concern about the earlier onset of certain cancers, including colorectal, breast and kidney cancers. The new research describes what's known as a 'birth cohort' effect, or a disease becoming more common among successive generations. Such an effect lends credence to the idea that people born after a certain time have had similar exposures to something that is increasing their cancer risk more so than among people born decades before, said Dr. Andrea Cercek, a medical oncologist at Memorial Sloan Kettering Cancer Center who was not involved in the study. And the fact that researchers have seen similar generational effects in colorectal and gastric cancers suggests there may be some shared risk factors between those cancers and appendix cancer, said Dr. Andrew T. Chan, a gastroenterologist and professor of medicine at Harvard Medical School who researches the epidemiology of colon cancer and also was not involved in the study. Diet is one such possibility, he said. Our consumption of ultraprocessed foods has increased over time, and these foods — particularly processed meats and sugar-sweetened beverages — have been associated with increased risk for colon cancer.
