A new study has suggested that screening for colorectal cancer screening should start at age 50.

In the study, researchers at the John Hopkins University found that colorectal adenomas - the precursor polyps in virtually all colorectal cancers - occur infrequently in younger adults but the rate sharply increases after age 50.

"While colorectal polyps are rare in adults aged 30 to 50, our study reveals an increase in polyp prevalence with age and a dramatic increase in colorectal adenoma incidence occurring in adults over the age of 50," said Francis M. Giardiello, MD, of The John Hopkins University and lead author of the study.
"Understanding the natural occurrence of colorectal polyps, especially in younger adults, is important to the development of colorectal cancer prevention strategies," Giardiello added.

Treatment for Colorectal Cancers may involve surgery,chemotherapy, radiation therapy or biological therapy. Some people require a combination of treatments.

This rate sharply increased after age 50 with the prevalence of polyps ranging from 10.1 to 12.06 percent in the sixth and ninth decade, respectively. The study results quantified the number of adenomas typically found in people under the age of 50.

In younger adults, adenomas were more prevalent in Caucasians compared to African Americans; however, in older adults, the reverse was true. Regardless of age, adenomas were more prevalent in men than women.

Older Women Who Smoke are at Increased Risk of Colorectal Cancers

Colonoscopy, which provides the most comprehensive view of the colon, is the definitive test for colorectal cancer screening.
Colonoscopies allow gastroenterologists to view the entire colon and rectum for polyps or cancer and during the same exam remove pre-cancerous polyps.
It is the test most gastroenterologists recommend as the single best screening exam for colorectal cancer. It is the only method that combines both screening and prevention (by removal of pre-cancerous polyps).
The study was published in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute.
