"Contrary to overall cancer trends, there's been an increase in certain cancer diagnoses in people under 50. From 2010 through 2019, the incidence of 14 cancer types increased among people in this demographic. The big question is, why? Does it have to do with lifestyle choices? Are there environmental factors at play? What can be done to mitigate risk? Welcome to "Harvard Thinking," a podcast where the life of the mind meets everyday life."
"Timothy Rebbeck: Tim Rebbeck. I'm the Vincent Gregory Professor of Cancer Prevention at the Harvard Chan School and the Dana-Farber Cancer Institute. Laine Perfas: He's a cancer epidemiologist and studies global cancer trends and disparities. Then: Ng: Kimmie Ng. I'm an associate professor of medicine at Harvard Medical School. Laine Perfas: She's also a medical oncologist at Dana-Farber Cancer Institute and the founding director of the Young-Onset Colorectal Cancer Center."
Overall cancer rates have declined, but incidence of several cancers is increasing in people under 50. Colorectal cancer risk is markedly higher among younger cohorts; someone born in 1990 has about four times the colorectal cancer risk and more than double the colon cancer risk compared with a person born in 1950. From 2010 to 2019, incidence rose for 14 cancer types among people under 50. Possible drivers include lifestyle changes and environmental exposures, but specific causal factors remain uncertain. Epidemiologists and oncologists emphasize the need for research into etiology, prevention, screening, and mitigation strategies.
