“Colorectal Cancer Increases in Young Adults”
Inexplicably, colorectal cancer is on the rise in young adults, which has experts puzzled. An American Cancer Society study has found that rates of colorectal cancer (CRC) have risen dramatically in younger adults (younger than 55 years). The increase in incidence is seen particularly among the so-called Generation X (persons born from the early 1960s to the early 1980s) and millennials (persons born from the early 1980s to the early 2000s). Rebecca Siegel, MPH, of the American Cancer Society, said, “People born in 1990 now have double the risk of colon cancer and quadruple the risk of rectal cancer compared to people born around 1950.” Investigators found that risk for CRC declined until the first half of the 20th century. People born around 1950 have the lowest risk for disease. The risk for CRC began increasing after that date. Experts believe that screening should start at age 50 years for average-risk individuals and at age 40 for those with a family history of CRC or adenomas in a first-degree relative.
