Medicos find more evidence of baldness and prostate cancer link

A new study, published in the Journal of Clinical Oncology, lends weight to the notion that male pattern baldness and prostate cancer may be linked.

Prostate cancer is the second most common cancer among men. Emerging evidence suggests that prostate cancer and male pattern baldness – progressive scalp hair-loss in a distinct pattern – are both connected to increased levels of male sex hormones (androgens) and androgen receptors, supporting the idea of a biological link between baldness and prostate cancer.

The study was based on an analysis of data from 39,070 men in the prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial. The results indicate that men who had moderate baldness affecting both the front and the crown of their head at age 45 were at a 40 percent increased risk of developing aggressive prostate cancer later in life. The mean age at the time of prostate cancer diagnosis was 72.

“Our study found an increased risk for aggressive prostate cancer only in men with a very specific pattern of hair loss, baldness at the front and moderate hair-thinning on the crown of the head, at the age of 45. But we saw no increased risk for any form of prostate cancer in men with other hair-loss patterns,” said senior study author Michael B. Cook, an investigator at the National Cancer Institute in Bethesda, MD.

Cook believes that if the new findings are confirmed by further studies, medical assessment of baldness could possibly be used to help identify men who may be at increased risk of aggressive prostate cancer. His research team is currently conducting two additional cohort analyses exploring the relationship between male pattern baldness and risk of developing and dying from prostate cancer.

“While our data show a strong possibility for a link between the development of baldness and aggressive prostate cancer, it’s too soon to apply these findings to patient care,” he concluded.
