TL;DR

The hypothesis that blind persons are at lower risk of cancer in a follow-up study linking a cohort of 17,557 persons with visual impairment with cancer incidence data of the Finnish Cancer Registry is tested and the result is strongly against the hypothesis of a systemic protective effect related lack of visible light.

Abstract

Our findings add to the suggestive epidemiological evidence for a decreased risk of hormone-related cancers in people with visual impairment and, consequently, a relationship between visible light at night and breast cancer risk. The result is strongly against the hypothesis of a systemic protective effect related lack of visible light.
