Expert: Cancer Vaccines Prevent Recurrence, Not Initial Onset

Doctors are developing vaccines to help prevent cancer from returning in people who have already been treated.

These vaccines are different from those that prevent cancer in the first place.

They use immunotherapy to teach the body's defense system to find and destroy any remaining cancer cells.

This was discussed at a conference focused on colorectal cancer, which is becoming more common.

Doctors are also working on tailoring treatments to each patient, which is called personalized medicine.

Over 200 experts attended the conference to discuss the latest treatments.
