Potential contribution of aspirin to cancer control programmes.

Chemoprevention describes the potential of chemicals to intervene and block multi-stage carcinogenesis. Aspirin (acetylsalicylate) is showing cancer chemopreventive potential and the medicine has public health potential given that low doses also reduce the risk of cardiovascular events by up to 30%. Whilst recognizing that aspirin has undesirable effects, such as increasing the risk of stomach bleeding, perhaps the medicine may compliment other cancer control programmes such as screening and lifestyle measures. Furthermore, perhaps the cancer chemopreventive potential of aspirin might be mediated, at least in part, by salicylate, which is present in fruits and vegetables. Salicylate might, therefore, be considered to be a nutraceutical. Furthermore, there are a number of matters that arise including the potential for the public health field to further advocate the self-care preventive agenda, which might include aspirin. Perhaps, it is now timely for a conference on the public health potential of aspirin to be convened.
