Men with male pattern hair loss (androgenetic alopecia) at age 45 have a higher chance of aggressive prostate cancer later in life according to researchers. The study reviewed over 39,000 cases of men aged from 55 through 74 to self-assess their level of hair-loss at age 45. Those with moderate hair loss on the front and crown of the head were 39 percent more at risk of prostate cancer.
The research published in the Journal of Clinical Oncology investigated the association of male pattern baldness at age 45 with risks in prostate, lung and colorectal cancer screening trials.
During follow-up, 1,138 prostate cancer cases were diagnosed, 571 of which were aggressive. The average age of diagnosis was 72.
Dermatologists explain that prostate cancer and male pattern baldness are both tied to increased High levels of androgens can affect hair follicles, causing thinning and loss of hair. Androgens can also cause prostate cancer cells to grow. Dermatologists also advise that further study would be needed to support whether baldness patterns should be part of a screening system. Full details of the study are in the Journal of Clinical Oncology.
