Serotonin, the 'Happiness Chemical,' May Fuel Cancer Growth

Imagine serotonin as a messenger in your body.

We usually think of it as the 'happy messenger' that helps you feel good.

But scientists have found that serotonin, especially the kind made in your tummy, can also act like a messenger for cancer.

This tummy serotonin can go into cells and tell certain genes to start growing, which can help tumors get bigger.

This is different from how serotonin works in your brain to control your mood.

Researchers are now trying to figure out how to stop this cancer-helping messenger without affecting the happy messenger.

They are looking at special medicines that can block these messengers from getting into cancer cells or therapies that can turn off the bad genes.

This could lead to new ways to fight cancer.
