Cancer Risk from Night Shift Work and How Melatonin Might Protect Against It

Night-shift work may be associated with an increased risk of cancer due to disruptions in circadian rhythms and lower melatonin production.

• Circadian rhythm disruption is hypothesized as a contributing factor to cancer risk among night-shift workers.
• Decreased melatonin production is suggested to play a role in the potential carcinogenic effects of night-shift work.
• Night-shift workers may adopt unhealthier lifestyles, which could further elevate their risk of developing diseases like cancer.
• No experimental studies have specifically tested methods to reduce cancer risk in night-shift workers.
• Current research lacks focused studies on melatonin as a preventive measure against cancer specifically for night-shift workers.
