A tumour is like a group of cells playing a game of ‘follow the leader’ but they forget the rules. Our body is made up of tiny building blocks called cells. These cells know when to grow and when to stop, just like how we know when to start and stop playing. But sometimes, some cells forget the rules and keep growing, forming a lump called a tumour.
Imagine your body is a beautiful garden. Each plant knows how much space it needs to grow. A tumour is like a plant that keeps growing and growing, taking up too much space and pushing other plants aside. This can make it hard for the garden to stay healthy.
Think of your body as a busy city. Each cell is like a person with a job to do. A tumour is like a group of people who stop doing their jobs and just stand in one place, making it hard for everyone else to move around and work properly. This can make the city, or your body, not work as well as it should.
