Janet Jackson to undergo surgery

Janet Jackson has postponed her Unbreakable World Tour immediately after doctors recommended she undergoes a surgery. The type of surgery was however not specified in her message on Instagram. 

The next concert was scheduled for January 9 in Denver, Colorado. In October, she also had to postpone a number of concerts in order to rest her vocal cords. The latest postponement is expected to affect the schedule of the other events in the North American leg of the Unbreakable World Tour.
