In the News – Health Canada Says Finasteride and Dutasteride Increase Prostate Cancer Risk

Snippet from the article:

Health Canada is informing health professionals and the public that certain prescription drugs may be associated with an increased risk of developing a serious form of prostate cancer known as high-grade prostate cancer.

High-grade prostate cancer is an aggressive type of prostate cancer that grows and spreads more quickly than low-grade prostate cancer. This type of cancer is rare, and the increased risk seen with prescription drugs finasteride and dutasteride is still considered very small.

New warnings on this risk have been added to the Canadian drug labels for finasteride and dutasteride products.

There it goes again. Like the pendulum of a clock, the claims on cancer swing in bother directions (positive and negative). The focus here was on 5mg dose of finasteride (for treating enlarged prostate), not 1mg that is used to treat hair loss. And the focus of the study was on the rarer high grade malignancies classified by microscopic assessment of a pathologist. These conclusions may not apply to the lower dose, nor may they not apply to the young men under 50 years old.
