Snippet from the article:
Men being screened for prostate cancer can dramatically reduce their risk of unnecessary treatment by taking an already-approved drug, a new study shows.
Although doctors still hotly debate the value of prostate screening, most agree that the PSA (prostate specific antigen) test leads some men to be “overdiagnosed” and even “overtreated,” because it detects many tumors that won’t ever turn deadly.
Many men are unaware that some prostate tumors — while technically malignant — are essentially harmless, growing too slowly to ever cause trouble in their lifetimes. Men are actually better off if these tumors are never found, says Otis Brawley, chief medical officer at the American Cancer Society.
Read the rest — Drug makes PSA screening test more reliable
This is a seven year study of 19,000 men that showed taking finasteride makes the PSA test much more accurate.
The article goes on to say that the study found that “men on finasteride were 43% less likely to be diagnosed with a ‘low-grade’ prostate cancer — the kind most likely to lead to unnecessary treatment“, though there was no difference in survival rates between those that took finasteride and those that took the placebo.
