In Houston, testing is currently underway on vaccines that aim to prevent colon cancer. This development is particularly relevant for individuals with a high risk of colorectal cancer. A local doctor is involved in testing a new vaccine and has a personal connection to the issue, as they have Lynch syndrome.

This condition is a faulty gene that can be inherited from a parent and significantly increases the risk of colorectal cancer, as well as other types of cancer. Further information on this testing and the vaccine can be found through Houston Public Media, which has reported on the local doctor's involvement and the details of Lynch syndrome.
