Multimodal cancer therapy means using more than one way (or mode) to treat cancer. It's like when you use different tools to build something instead of just one tool. So instead of just using one treatment, like medicine or surgery, doctors use a combination of treatments to fight cancer.
Think of cancer as a group of bad guys in your body. To get rid of them, doctors have to use different methods to attack them from all sides. So, for example, they might use medicine to kill the bad guys, surgery to remove them, and radiation therapy to make sure they don't come back. Each of these methods has its own strengths, and using them together is like a team of superheroes with different powers working together to save the day.
Multimodal cancer therapy can be a bit tougher on your body than using just one treatment. It's like doing a lot of homework all at once instead of just a little bit every day. But in the end, it can be more effective at getting rid of the bad guys and preventing them from coming back.
