New Vaccines May Help Ward Off Colon Cancer
Newser • • health
Key Points:
- Dr. Stacy Norton, who has Lynch syndrome—a genetic condition increasing colorectal cancer risk—participated in testing a new vaccine aimed at preventing cancer in high-risk individuals like herself and her children.
- Lynch syndrome affects about 1 million Americans and significantly raises the risk of colorectal and other cancers, typically requiring frequent colonoscopies to detect and remove precancerous polyps.
- Researchers are developing vaccines designed to train the immune system to intercept early cancer development, with at least three vaccines in development and two currently in early clinical trials in the US.
- The vaccine Norton helped test showed promising results, leading to plans for a larger study next year, and for the first time since 2014, her post-vaccination colonoscopies were free of polyps.
- If successful, these vaccines could reduce the need for yearly colonoscopies for Lynch syndrome patients, potentially transforming cancer prevention for those with the genetic mutation.
