Aspirin and painkillers such as ibuprofen have been deemed too risky for use in the prevention of colon cancer, according to a federal task force.

The risk of intestinal bleeding, stroke, kidney failure, and other health problems led the US Preventative Services Task Force to conclude that taking more than 300 milligrams per day of drugs like Motrin, Advil, and Aleve is just too risky to outweigh the potential benefits of preventing cancer. And while taking less than 100 milligrams of such drugs can reduce the risk of heart disease, it does nothing to lower the rate of colon cancer.

Details about this task force study are published in Monday's issue of the Annals of Internal Medicine.

Twenty years from now, no one will die of cancer and heart disease, according to an expert in Perth, who believes advances in genetic technology will one day leave death by cancer in the dust.

Professor John Shine, director of the Garvan Institute for Medical Research in Sydney, says people will still get cancer -- they just won't die from it. He shared last week at a genetics conference in Perth, "I think there's no doubt death from cancer will be confined to the annals of history, And I think a very similar thing will apply to heart disease."

Despite reservations from some about genetic technology, Shine believes the desire to combat cancer -- once and for all -- will prevail over political opinion. And so that leaves only technical obstacles in the way. It's just a matter of time before these scientific hurdles are no longer issues.

Shine, known as the father of cloning, pioneered gene research in the 1970s when he identified the genes for insulin and the human growth hormone.
