New evidence suggests aspirin can prevent cancer

Taking a low dose of aspirin every day can prevent and possibly even treat cancer, fresh evidence suggests.
The three new studies published by The Lancet add to mounting evidence of the drug's anti-cancer effects.
Many people already take daily aspirin as a heart drug.
But experts warn that there is still not enough proof to recommend it to prevent cancer cases and deaths and warn that the drug can cause dangerous side effects like stomach bleeds.
