Cancer is like when your body is a big city, and the cells are the tiny people living in it. Usually, these cells know what to do, like when to grow and when to stop. But sometimes, some cells forget the rules, like naughty kids who don’t listen. They start growing too fast and don’t stop, making a big crowd that shouldn’t be there. This crowd is called a tumor.
Think of your body as a beautiful garden. Each flower is a cell, and they all have their special spots. But if one flower starts growing too fast and too big, it can cover other flowers and take their space. This makes it hard for the garden to stay healthy and pretty. That’s what happens when cancer cells grow too much.
Another way to think about cancer is like a game where everyone has to follow the rules. If someone cheats and doesn’t follow the rules, it can ruin the game for everyone else. Cancer cells are like the cheaters. They don’t follow the body’s rules, and that can make the body feel sick.
