There are many risk factors for head and neck cancers.
Age and lifestyle factors, such as alcohol and tobacco use, are the biggest.
But risk factors vary, depending on the type of cancer.
It's important to note that having any or all of the known risk factors does not necessarily mean that a person will develop a head and neck cancer.
On the other hand, having no risk factors does not mean that a person cannot develop a head and neck cancer, either.
