Does Aspirin Prevent Cancer?

Overview

Studies seem to show that daily aspirin use helps prevent some types of cancer, such as colon cancer. But daily aspirin use increases the risk of bleeding inside your body, such as in the stomach. The evidence isn't strong enough yet to convince experts that the benefits outweigh the risks.

It's best to talk to your doctor so that you understand the possible benefits as well as the possible risks. Your doctor might recommend a daily aspirin to help prevent cancer if:

  • Your risk of cancer is higher than normal,
  • And your risk of a problem from aspirin is low.
