Drinking coffee and tea can help protect against cancers in the mouth, throat, and voice box, a study says.
Researchers in the US looked at 25,000 records from 14 previous studies to see what people with head and neck tumors eat.
Results show that drinking four cups of caffeinated coffee a day can reduce the risk of head and neck cancer by 17%.
Tea and coffee contain substances that can fight cancer and inflammation, which may help reduce the effects of harmful substances.
Drinking decaf coffee can also lower the risk of mouth cancer by 25%.
However, drinking too much tea might increase the risk of throat cancer.
More studies are needed to understand the effects of coffee and tea on cancer risk.
Head and neck cancers are decreasing in many wealthy countries, but they are still a big problem in other places.
We need to learn more about how coffee and tea can help prevent cancer.
This study was published in the journal Cancer.
