Carcinogen

A carcinogen is something that can make your body sick in a really bad way. It's kind of like a bad guy that sneaks into your body and causes damage.

Imagine if you are building something with blocks and someone comes along and starts knocking them down. That's what a carcinogen does to the cells in your body. They can't do their job properly and sometimes they divide and multiply really fast which can lead to cancer.

Some carcinogens are things like smoke from cigarettes, chemicals that are used in some workplaces, and even certain types of food. It's important to try and avoid these things as much as possible so that we can keep our bodies healthy and strong!
