Shift work and risk of breast cancer: updated meta-analysis of observational studies
Summary
Pooled studies exploring breast cancer risk and night/rotating shift exposure; dose/duration patterns remained key sources of heterogeneity.
Why It Matters For Night Shift Workers and Night Owls
This systematic review and meta‑analysis how years of night‑shift exposure shows 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.
