Men Taking Dutasteride Received Better Diagnosis Of PSA Tests

December 26, 2010

So many times you would leave the urologist’s office, after having the results of a PSA test explained, filled with much uncertainty as to whether the indicators could be incorrect. Knowing that PSA screening is not a precise diagnostic instrument for determining cancer of the prostate, can lead to anxiety and depression. But those days are almost over. New research study found PSA screening is more reliable in men taking the PSA level reduction drug dutasteride.

Dutasteride is a dual 5-alpha-reductase inhibitor, approved by the FDA for the treatment of symptomatic benign prostatic hyperplasia (BPH), better known as enlarged prostate.

A hormone, dihydrotestosterone (DHT), causes the prostate to slowly grow over time. Dutasteride slows down the production of DHT over time, leading to shrinkage of the enlarged prostate, and reducing the symptoms of BPH.

Dutasteride reduces the risk of prostate cancers by keeping the turmors small enough to avoid detection by a biopsy. Thus, men taking Dutasteride who still show a subsequent rise in PSA levels should be associated with having aggressive high-grade cancer.

This new study reveals how Dutasteride enhances the ability of rising PSA levels to detect high-grade cancers that require early diagnosis and treatment, while decreasing the detection of tumors that are harmless. However, it doesn’t mean men should take dutasteride to better PSA scores.



Prostate Tumors Shrinked With Flaxseed

June 20, 2007

Researchers at Duke School of Nursing discovered that flaxseed supplement actually slows prostate tumor growth. Flaxseed is rich in Omega-3 fatty acids, and fibers known as lagnans. Flaxseed is edible, but has to be grounded since the seed has an indigestible coat. Sprinkle it on food or mix with beverage for best result.

Researchers found that men in the flaxseed group had the slowest prostate tumor growth rates compared to the other groups. “The seed,” said Dr. Wendy Demark-Wahnefried, the lead investigator for the study, “may be able to interrupt the chain of events that leads cells to divide irregularly and become cancerous. Another reason could be that the Omega-3 fatty acids prevents cancer cells from sticking to body cells.”

The study was funded by the National Institute of Health, and researchers from the University of Michigan, and North Carolina University at Chapel Hill participated
