Men who begin balding in their 20s have a greater risk of developing prostate cancer, according to a study published in the Annals of Oncology and reported by NPR’s “Shots” health blog.

For the study, researchers evaluated 669 men. Of these participants, 388 had prostate cancer. The remaining 281 had no history of the disease. Scientists showed the men pictures of various stages of hair loss––full head of hair, receding hairline, balding crown or both types of balding. Then the men noted which way their hair looked at ages 20, 30 and 40.

Findings showed men who reported some form of balding in their 20s were more likely to be in the prostate cancer group than men who began balding at age 30 or older.

How is this info useful? Well, the study’s results could help determine which men are at greater risk for prostate cancer, researchers said. This would help doctors discern which men might need prostate cancer prevention drugs or more frequent screenings to test for rising PSA levels.
