John Farnham is now in a "stable condition" after having part of his jaw removed while undergoing treatment for mouth cancer.
The 73-year-old singer underwent a mammoth 12-hour operation on Tuesday (August 23) after recently discovering a growth which turned out to be cancerous.
In a statement, John's family said: "John has been through an eleven-and-a-half-hour surgery in Melbourne yesterday and is now in a stable condition in ICU. The cancer tumour was located in his mouth, and it has been successfully removed."
