Older men with high levels of testosterone may have an increased risk of prostate cancer, a new study from Australia says.
In the study, men ages 70 to 88 with higher
testosterone levels were 9 percent more likely to develop prostate cancer over a seven-year period than men with lower levels.
Testosterone is needed for the normal growth of the prostate, and it's possible that high levels of the hormone accelerate the growth of prostate cancer, the researchers said.
