A local doctor is participating in vaccine testing to prevent colon cancer. The doctor, who has a family history of the disease, is among those with Lynch syndrome, a genetic condition that increases the risk of colorectal cancer. This condition affects an estimated 1 million Americans, who are often advised to undergo frequent colonoscopies to detect and remove precancerous growths.

Further details on the vaccine testing are available from KPRC 2 / Click2Houston.
