Okay kiddo, the truth about cancer can be a bit complicated but I'll try to explain it in a simple way.
First, let's understand that cancer is when some of the cells in our body start to grow and divide in a way that they shouldn't. When we get sick with a cold or the flu, our body fights off the germs with our immune system. But with cancer, the cells keep growing and don't stop, which can be very dangerous.
There are many different kinds of cancer, and they have different causes. Some cancers can be caused by things like smoking or sunlight, while others might be caused by things we don't know yet.
When someone has cancer, doctors will try to find out what kind of cancer it is and how far it has spread. They might use tests like X-rays or scans to look inside the body.
The treatment for cancer also depends on what kind of cancer it is and how far it has spread. Sometimes doctors will use surgery to remove the cancer, while other times they might use radiation or chemotherapy to kill the cancer cells.
It's important to remember that while cancer can be scary, many people are able to beat it and live healthy lives. And it's also important to try to stay healthy to help prevent cancer, like eating healthy foods, getting enough sleep, and not smoking.
I hope that helps you understand a bit more about the truth of cancer, kiddo!
