I had surgery for an invasive squamous cell cancer tumor in the back of my neck at the base of my skull earlier this year. Recently, a friend gave me a biography of George Harrison, which states that his cancer first presented as a tumor in the back of his neck etc. in 1997. Was his cancer oral cancer, or cancer of the neck, or or something else? I am still confused. Are there types of regular checkups that I should be having apart from dermatological? Many thanks.
