Val Kilmer's family believe his health is suffering because of his religious beliefs.
The 55-year-old actor was rushed to hospital last week after bleeding from his throat but has denied reports he underwent emergency surgery and has a tumour.
However, insiders told TMZ that Val has known since last summer he had a tumour but wouldn't seek treatment because of his Christian Science beliefs, which are that prayer heals, not medical treatment.
The Batman Forever star had reportedly had trouble speaking for some time and hid his swollen neck with scarves and other clothing items, but didn't confess he was in pain as it would be an admission that prayer hadn't worked.
According to the insider, anyone who persisted with asking the actor to seek medical help was simply cut out of his life.
