Tumour

Sometimes, our bodies make extra cells that stick together and form a lump called a tumour. Think of it like building with too many LEGO bricks in one spot! Most of the time, these lumps are harmless, like a little bump on your skin. But sometimes, they can be a bit more serious and need a doctor to check them out. It's like when you get a splinter, you might need help to get it out.

People have known about tumours for a very, very long time, even before there were doctors like we have today! Ancient Egyptians wrote about them on old scrolls. They didn't have fancy machines to see inside, but they knew these lumps could be a problem. Over many years, scientists and doctors have learned more and more about how tumours grow and how to help people with them.

Doctors care about tumours because they can sometimes make people feel sick. If a tumour grows too big or in the wrong place, it can push on important parts of your body, like your tummy or your brain. Learning about tumours helps doctors figure out if a lump is okay or if it needs special medicine or treatment to help the person feel better and stay healthy.

Our bodies are made of tiny building blocks called cells. Usually, cells grow and divide when we need them, and old ones go away. But sometimes, cells start growing too much and don't stop. They just keep dividing and piling up, making a lump. It's like a plant that grows too fast and takes over the garden! Doctors study these cells to understand why they grow so much.
