Rise Seen in Colorectal Cancer in Under-50 Adults (Update2)

June 8 (Bloomberg) — Colorectal cancer rates are rising in adults younger than 50 with the biggest jump, more than 5 percent, recorded in those ages 20 to 29, a study found.
People older than age 50 began getting tested routinely for the disease in the mid-1980s, leading to a 2.8 percent yearly decline from 1998 to 2005 in adult men overall, according to the American Cancer Society report. Younger Americans, who make up 9 percent of the 146,970 cases expected by the society this year, aren’t usually tested for the disease, the second most common cause of cancer death in U.S. adults.
The study was published today in the journal Cancer Epidemiology Biomarkers and Prevention. The research didn’t identify a cause for the increase. Elizabeth Ward, vice president of surveillance and health policy research at the society, said rising obesity and diabetes rates and diets heavy in red and processed meats are likely culprits.
“The fact that cancer is affecting younger people is worrisome,” said Ward, a study author, in a telephone interview. “We want to educate health-care practitioners and the public that this increase is happening, and it may be related to obesity and unfavorable dietary patterns.”…read more here..
