How to Search For Information You Need
In general, finding information free on search engines requires a lot of patience and is time consuming. Free websites most likely provide only limited information if you are searching for something important. The best choice is to buy it because bought information is usually written by specialists and is copyrighted. [August 13, 2008 10:25:46 am] By Chic Ngo
Why Obesity May Lead To Poorer Prostate Cancer Outcomes
By Glenn Sheiner
Most people are aware of the negative health effects of being overweight or obese.
Now, it appears that obese patients may have poorer outcomes if diagnosed with prostate cancer for at least two distinct reasons.
It appears that obese men tend to be diagnosed with more aggressive forms of the disease as compared to non-obese men. The reason for this is that it appears that the PSA blood test is not as reliable in obese men as a predictor of prostate cancer.
In a recent study of 3400 men who had PSA testing, researchers found that the risk of an aggressive cancer diagnosed by an elevated PSA was twice as high in obese patients as compared to non-obese patients.
The reason postulated for this is that obese patients have greater blood volume which may dilute the PSA and lower results. By the time a PSA was elevated in obese patients, the cancer was more spread.
Researchers suggest therefore that the index of suspicion be higher for obese patients and that PSA levels which would be considered as worthy of further investigation be lowered in obese patients.
It should be noted that the definition of obesity is a Body Mass Index (BMI) of 30 or above.
OBESITY AND PROSTATE CANCER SURGERY
A second recent study showed that obese patients were 60% more likely to have recurrence of prostate cancer after surgery for prostate cancer removal.
In this study of 1434 men, obesity was defined as a BMI of 35 or over.
The reason postulated for the increased recurrence rate was the technical difficulty of operating on obese patients.
So, here's two more good reasons to lose that excess poundage.
