This is a delusional statement he is terminal. What he has is incurable and metastasizing.

His brain is malfunctioning and needs to quit. All us in AZ need to write his office to urge him to resign and spend his remaining time with family and friends. No one is irreplaceable.

Most likely you may be right. But I will say that my Brother-in law was diagnosed with the exact type of brain cancer 19 years ago - he's still alive.

You're probably right that it's "incurable and metastasizing." See his own medical team's statement from the article:

'On Friday, July 14, Sen. John McCain underwent a procedure to remove a blood clot from above his left eye at Mayo Clinic Hospital in Phoenix,' a statement said. 'Subsequent tissue pathology revealed that a primary brain tumor known as a glioblastoma was associated with the blood clot.' (My emphasis.)

The term, "was associated with the blood clot," is seriously discouraging since it does not state that the tumor was removed; indeed, it implies that the underlying tumor, or parts thereof, remain and continue active. Teddy Kennedy is definitely making space for another dinner guest.
