Linked: Baldness, Risk for
Over the past 2 decades, male pattern baldness has repeatedly and consistently been found to be associated with an increased risk for prostate cancer in observational studies.
The tie makes theoretical sense in terms of physiology because androgens play a role in hair loss and prostate cancer development. Plus, both conditions have a degree of heritability
Nevertheless, the established risk factors for prostate cancer continue to be older age, black race, family history, and genetic aberrations, such as BRCA mutations.
But a new study has added urgency to the question of whether or not baldness is also a risk factor.
For the first time, researchers have found that baldness is tied to the risk for
In fact, the risk is 1.5 times greater in bald men than in those with no baldness, according to an analysis of data from the large American prospective, longitudinal cohort study known as the National Health and Nutrition Examination Survey Epidemiologic Follow-up Study (NHEFS).
The results were published in the February 1 issue of the American Journal of Epidemiology.
Those findings are akin to another study conducted by Dr Cook’s team, which showed an association between baldness and aggressive prostate cancer in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial, as reported by Medscape Medical News.
