Okay kiddo, you know how we have medicine to help us feel better when we have a cold or a tummy ache? Well, scientists have also made medicine to try and help people who have something called cancer.
Cancer is when the cells in someone's body don't work properly and keep growing and dividing really fast, making a big lump called a tumor. This can make the person really sick and hurt their body.
Anti-cancer drugs are special medicines made to try and stop the cancer cells from growing and spreading. They're kind of like superheroes that go into the body and fight against the bad guys (the cancer cells).
There are lots of different types of anti-cancer drugs and some work by stopping the cancer cells from dividing and growing, while others can help the body's own immune system fight the cancer.
But, like all medicine, anti-cancer drugs can have some side effects. This means that while they are trying to help the person with cancer, they can also make them feel sick in other ways.
That's why it's important for doctors to find the right anti-cancer drug and dose for each person, and for the person to talk to their doctor about how they're feeling while taking the medicine.
Overall, anti-cancer drugs are important medicines that can help people with cancer, but they can also come with some challenges along the way.
