He writes:

    "I had surgery this [Thursday] afternoon to remove it and am now on complete vocal rest for a month or more. It's been a very long process in waiting to see if time was an alternative to surgery, but even given two weeks' voice rest (along with many other approaches), there was no change for the better."


Mayer was forced to cancel September concerts with Tony Bennett in Los Angeles and an appearance at the iHeartRadio Music Festival in Las Vegas after being diagnosed.
