Could Years of Night-Shift Work Affect Breast Cancer Risk?

Our bodies have an internal clock that helps manage sleep and other processes.

Night-shift workers are awake when it is dark and often sleep during the day.

This can disturb the body’s usual timing.

Researchers are studying whether that disruption might affect cancer risk.

They are also looking at hormone changes and light exposure at night.

The International Agency for Research on Cancer says night-shift work is probably carcinogenic to humans.

But the evidence from studies in people is limited.

The article says this is a reason to learn more, not to panic.

Key facts

Body clock: The circadian rhythm is an internal 24-hour clock.
Usual functions: It regulates sleep, hormone activity and other biological processes.
Night-shift pattern: Workers stay awake under artificial light at night and try to sleep during the day.
Research focus: Researchers are examining circadian disruption, hormone regulation and light at night as possible contributors to cancer.
IARC assessment: The International Agency for Research on Cancer classifies night-shift work as probably carcinogenic to humans.
Evidence in humans: The article says the evidence in humans is limited.
