I've done quite a bit of research since I was diagnosed, but find I still don't quite understand cancer, and have some fundamental questions.

With all the bad news on the forum lately, I wonder what type of head and neck cancer is considered aggressive. Is(are) all types squamous cell-carcinoma aggressive? Is the degree of aggressiveness based on location, different types of squamous cell and/or the immunostains done on the biopsy?

Thanks
Sandy
