The type of gut bacteria in colorectal cancer tumors varies significantly between younger and older patients, offering a clue toward understanding why cases are rising in people under 45, according to a study due to be presented at next week's American Society of Clinical Oncology annual meeting.

Why it matters: While the incidence of colorectal cancer in the U.S. has declined overall, it's risen dramatically among patients under 45, since the mid-1990s.

This study points to possible bacterial factors at play, he said.

Details: Other studies, including one published this week in Nature Medicine, have examined the presence of bacteria in metastatic colon cancer.

Between the lines: It's a small study, covering 63 patients, Weinberg said, but it was robust with its inclusion of survival data, tumor genetic information and diet questionnaire results from participants.
