Scientists at the University of Washington School of Medicine examined 2,000 men aged between 40 to 47, half of whom were diagnosed with prostate cancer. They discovered that men, who went bald by the age of 30, had 45 percent lower risk of developing prostate cancer, if compared to men, who did not lose hair at an early age.
Bald men had higher levels of testosterone, male hormone, which leads to the shrinkage of hair follicles and hair thinning. The findings of the study were surprising for the scientists, as previous studies suggested that high levels of testosterone may stimulate the development of prostate cancer.
Researchers say that further studies are needed to understand how testosterone affects body tissues and its role in prostate cancer.
The study was published in the journal Cancer Epidemiology.
