Men who go bald by 30 at lower risk of prostate cancer
According to researchers from the University of Washington School of Medicine, bald men might be at a health advantage: in a study of 2,000 men aged 40 to 47, they found that men who go bald by 30 appear to be at lower risk of prostate cancer, the BBC reports. They credited this to high levels of testosterone, the male sex hormone, in those who go bald earlier. In the study, half of the men had prostate cancer. Researchers looked at the rate of tumours in those who said their hair had thinned by age 30, versus those who didn’t.Men who started going bald on the top of their heads and had receding hairlines had a 29 to 45 per cent reduction in the rate of prostate cancer, they found, suggesting that high levels of testosterone could be protective against the disease. By age 30, about 25 to 30 per cent of men have some baldness, with half of all men suffering significant hair loss by age 50.
