Testing is underway for vaccines that target colon cancer. A doctor from Houston is participating in the testing, motivated by a family history of aggressive tumors at young ages. The doctor has a faulty gene known as Lynch syndrome, which puts her at high risk for colorectal cancer.

People with this condition often undergo frequent colonoscopies to remove precancerous growths. Further details about the vaccine testing are available from KSAT 12. The goal of the vaccines is to teach the immune system to intercept colon cancer before it develops.
