Shorter telomeres associate with a reduced risk of melanoma development.

ABSTRACT: Epidemiologic studies have linked shortened telomeres with the development of many cancers. However, recent studies have suggested that longer telomeres may lead to prolonged senescence in melanocytes, providing increased opportunity for malignant transformation. We therefore examined whether shorter prediagnostically measured relative telomere length in peripheral blood leukocytes (PBL) was associated with a decreased risk of cutaneous melanoma. Telomere length in prospectively collected PBLs was measured in incident melanoma cases and age-matched controls selected from participants in three large prospective cohorts: the Women's Health Initiative Observational Study (WHI-OS), the Health Professionals Follow-up Study (HPFS), and the Nurses' Health Study (NHS). Shorter telomere lengths wer
