Cancer-stricken McCain vows a return to work in US Congress
Former US presidential nominee John McCain has promised to return to work while making a good-natured dig at his Republican and Democratic colleagues who were jolted by news of the Senator's brain cancer diagnosis.
"I greatly appreciate the outpouring of support - unfortunately for my sparring partners in Congress, I'll be back soon, so stand by!" Mr McCain said in a tweet.
The 80-year-old, the GOP's presidential nominee in 2008, was diagnosed with glioblastoma, an aggressive type of brain cancer, according to doctors at the Mayo Clinic in Phoenix, who had removed a blood clot above his left eye last Friday.
"Subsequent tissue pathology revealed that a primary brain tumour known as a glioblastoma was associated with the blood clot," his office said in a statement on Wednesday.
The Senator and his family are considering further treatment, including chemotherapy and radiation, as he recuperates at his home in Arizona.
