What are bad cells?

Bad cells are cells that don’t work properly, just like a broken toy can't play well.

Imagine your body is like a big toy box full of different toys, each cell is like one of those toys, doing its own special job. Most of the time, all the toys work together to keep you healthy and happy. But sometimes, some toys get broken or stop working as they should. These are the bad cells.

Bad cells can cause problems in your body. For example:

• If the cells in your skin are bad, you might get a rash or a wound that doesn’t heal.
• If the cells in your brain are bad, you might feel tired or forgetful more often.

It’s like if one of your favorite toys kept breaking every time you played with it, it would make playing less fun. That's what happens when bad cells take over!
