Aspirin’s benefit in preventing colon cancer depends on DNA

NEW YORK (Reuters) – Cancer is the first disease where physicians have personalized treatment, matching a tumor’s genetics to the appropriate chemotherapy, and now it may be the first in which prevention, too, can be personalized.

Two decades after scientists discovered that aspirin might reduce the risk of colorectal cancer, a new study finds that it has that benefit almost exclusively in people with genes that produce high levels of a particular enzyme. Those whose DNA produces low levels of the enzyme benefit hardly at all, scientists reported on Wednesday in the journal Science Translational Medicine.
