Prostate Cancer Risk Factor

Men with susceptibility for prostate cancer will soon be identifiable through a simple DNA test. So hope scientists at the Swedish medical university Karolinska Institutet, who have shown that men carrying a combination of known risk genes run a four to five times higher risk of developing prostate cancer.

At present, men with suspected prostate cancer are identified mainly using what are known as PSA tests. However, the test has a relatively low sensitivity and better methods are needed.

"In the near future, it will be possible to combine PSA tests with simple genetic tests," says Professor Henrik Grönberg at Karolinska Institutet. "This means that fewer men will have to undergo unnecessary biopsies and that more prostate cancer diagnoses can be made."

It has long been known that prostate cancer is partly caused by inherited factors, which makes some men more likely to develop the disease than others.

Less Sugar Prolongs a Man's Sex Life

No sex, alcohol and other risk factors have been proven to cause a rapid development in prostate cancer, the ultimate blow that can ruin a man's sex life. Too few recover after surgery without remaining impotent. Now, a research led at Duke Prostate Center and published in the online journal Prostate shows that being a sweet tooth also harms the prostate. Tests made on lab mice underline that a decrease in insulin levels triggered by less sugars in the diet could stop tumor .

The chart that you provided a link to shows anomalies from the 1961 to 1990 mean. The globe is still far above the mean tempurature derived between 1961 and 1990, it can in no way be considered to be stable or cooling.

You know just because we didn't have a major volcanic eruption this year doesn't mean plate tectonics doesn't exist. Physics still rules and greenhouse gases are still going to cause warming even if every year isn't warmer than the last. Posted 24/12/07 at 4:12 PM EST | Alert an Editor | Link to Comment .
