Rotating night shift work and colorectal cancer risk in the nurses’ health studies
Summary
Across two large nurse cohorts, long-term rotating night shift work was not linked to overall colorectal cancer but was associated with higher rectal cancer risk after long durations.
Why It Matters For Night Shift Workers and Night Owls
Longitudinal tracking how years of night‑shift exposure tracked with cancer risk for night‑shift workers and night owls. Evidence trends connect cumulative night exposure with risk signals, which matters over a career rather than a single block. For night‑shift teams and individuals, this ties long‑debated rota features to concrete outcomes, making schedule talk about health, not preference.
