Following the postponement of The Unbreakable World Tour-due to a surgical procedure-Jackson could possibly have throat cancer. A source tells RadarOnline that doctors found a tumor on Damita Jo’s vocal chords.

“Doctors found a growth on Janet’s vocal chords that could be serious,” said the source. “It’s a medical condition that has to be taken care of immediately.”

Speaking to the site, Dr. Stuart Fischer explained: “God forbid that this should be cancer of the larynx. That would abruptly end her ability to ever perform again. Singing would be impossible.

“Surgery would be very complex, and followed by months of radiation treatment.”

Let’s just hope whatever Ms. Jackson is going through with her health, she makes it through unscathed.
