Fixing Body Clock Rhythms in Mice Shrinks Tumors

Scientists found that in mice with breast cancer, the tumors mess up the natural daily rhythm of a stress hormone called corticosterone.

When they fixed this rhythm by stimulating certain brain cells at the right time of day, the tumors shrank.

This is because the fixed rhythm helped the immune system fight the cancer better.

The researchers think this could one day help make cancer treatments work better and have fewer side effects.

They're still trying to figure out exactly how this works and why the timing is so important.
