The You’re The Voice singer is set to undergo surgery to remove a cancerous growth today.
Surgeons are confident they will be able to remove all the dangerous tissue.
“Cancer diagnosis is something that so many people face every single day, and countless others have walked this path before me,” Farnham said in a statement.
“The one thing I know for sure is that we have the very best specialist healthcare professionals in Victoria, and we can all be grateful for that. I know I am.”
The family has requested privacy during this time.
