Does testosterone cause prostate cancer?
In the 1840s, doctors did not know much about prostate cancer (or cancer). However, they found that men with metastatic prostate cancer lived longer in castration.
I should put it another way. They found that a man with metastatic prostate cancer lived longer than he was castrated (1). That's right, the effects of castration on a poor bastard's prostate cancer led several generations of doctors to believe that testosterone itself was promoting the disease. Funky, right?
Men with low testosterone levels are not afraid of TRT (testosterone replacement therapy). It does not increase the risk of developing prostate cancer. Consider the analysis of more than a quarter of a million men's records in Sweden, published in 201
The researchers found that men who had been prescribed testosterone for more than a year not only had no increased risk for prostate cancer, but the risk of aggressive disease had dropped by 50 percent.
And this is just the latest of many studies that suppress the myth that TRT causes prostate cancer. Researchers in the United Kingdom studied 1400 men who had received testosterone replacement therapy for up to 20 years and found only 14 cases of prostate cancer during the study (2).
This prompted the co-author of the study, Dr. Ing. Malcolm Carruthers, medical director at the Center for Men's Health in London, to say:
"This myth that testosterone replacement therapy is associated with prostate cancer has been deeply rooted in medical awareness for over 60 years Paper says no." Testosterone treatment is actually good for the prostate, not bad. "
