A new vaccine could change how doctors fight colon cancer forever

Researchers in the United States and Europe are testing a new generation of vaccines designed to prevent certain forms of colon cancer before tumors develop, offering hope to people with Lynch syndrome, an inherited condition that dramatically increases the risk of colorectal and several other cancers. Scientists believe the vaccines could train the immune system to identify and destroy precancerous cells years before they become life-threatening disease, according to ScienceDaily.
