I was reading your message and looking at your brother's and son's ages and time frames and thinking what a rough time you have had.

Raymond1971 is a poster on this board who has traced back some other relatives that had oral cancer. He is the only other person I can think of. And, I don't think his relatives were as closely related as your son and brother.

I have never read anything to suggest that oral cancer had any hereditary links. I am so sorry you had to experience two losses to this awful cancer.

My heart goes out to you.
