If you’ve ever had a mouth sore—like a cold sore or a canker sore—you know they can be annoying, even if they’re harmless.

But for a child with cancer, mouth sores may pose a health risk. A mouth sore opens a place for germs to get into the bloodstream. If your child has a weakened immune system—which is common for kids with cancer—those germs can be dangerous.   

Cancer treatments like chemotherapy and radiation can increase a child’s risk of developing mouth sores. And while sores aren’t always preventable, there are a few things you and your child can do to decrease that risk.
