The biggest-selling pop artist of the year has gone silent.
The British pop/soul singer Adele was forced to cancel the rest of her 2011 tour. Earlier this year, she suffered two vocal hemorrhages and will need to undergo surgery.
Singers are in a high-risk business. Many famous singers have needed similar treatment.
"Essentially, people who sing are vocal athletes," says Dr. Steven Zeitels, director of the Voice Center at Massachusetts General Hospital. "So you can look at this as a not unusual scenario as an athlete getting an injury in that area."
