男性45岁时某些类型的脱发是患有前列腺癌的危险征兆

"Our study found anincreased risk for aggressive prostate cancer only in men with a very specificpattern of hair loss, baldness at the front and moderate hair-thinning on thecrown of the head, at the age of 45. But we saw no increased risk for any formof prostate cancer in men with other hair-loss patterns," said seniorstudy author Michael B. Cook, PhD, an investigator in the Division of CancerEpidemiology and Genetics at the National Cancer Institute in Bethesda, MD."While our data show a strong possibility for a link between thedevelopment of baldness and aggressive prostate cancer, it's too soon to applythese findings to patient care."

“我们的研究发现，只有某些特性类型的脱发，头前面和头顶的头发在45岁时开始脱落，患侵略性前列腺癌的可能性增加。而其他类型的脱发则与患前列腺癌的风险关系不大，”位于马里兰州贝塞斯达的美国国家癌症研究所肿瘤流行病学和遗传学部门的高级研究员、本文作者迈克尔·b·库克博士说。“虽然我们的数据表明持续脱发很可能与侵略性前列腺癌有关联，但将这个发现应用于病人护理还为时尚早。”

Prostate cancer is thesecond most common cancer among men. Emerging evidence suggests that prostatecancer and male pattern baldness -- progressive scalp hair-loss in a distinctpattern -- are both connected to increased levels of male sex hormones(androgens) and androgen receptors, supporting the idea of a biological linkbetween baldness and prostate cancer development and progression.
