Sleeping less than 7 hours per night is linked to increased risk of prostate cancer mortality in men younger than 65 years of age, but not among their older counterparts, according to a study presented at the American Association for Cancer Research annual meeting in Washington.
While previous research uncovered a similar association among employed men, this study looks at sleep duration and prostate cancer mortality risk in men regardless of employment status, said lead author Susan M. Gapstur, PhD, MPH, of the American Cancer Society in Atlanta.
