Deadly cancer risk could drop with single 10-minute workout, study suggests

A single 10-minute workout may trigger blood changes that help fight colon cancer.

That's according to new research from scientists at Newcastle University, who found that exercise quickly changes the blood in ways that affect colon cancer cells in the lab.

In the study, the U.K. researchers exposed colon cancer cells to human blood serum collected immediately after exercise, finding that the cells repaired DNA damage faster and showed gene activity patterns linked to slower growth.
