When Low Testosterone Is A Really Bad Sign

In a man’s body, not all testosterone is created equal. And if you have a low-level prostate cancer, a reduced amount of one of those types is a very bad sign.

Some prostate cancers are so slow-growing and low-risk that experts often recommend surveillance of the problem, but not treatment unless the cancer becomes aggressive. But researchers at Pontificia Universidad Católica de Chile say that if you have one of these tumors and your free testosterone is at a low level, you are at an increased risk of developing fast-growing prostate cancer. (Free testosterone makes up only about 2 percent of your testosterone.)

“(Our) results suggest low levels of testosterone are associated with more aggressive prostate cancer. This contradicts long-held beliefs that high testosterone is risky for prostate cancer, and low testosterone is protective,” says researcher Ignacio San Francisco, M.D. “In borderline cases, the presence of low values of free testosterone may help determine whether it is more prudent to initiate treatment rather than continue observation.”
