Janet Jackson is reportedly undergoing throat surgery to remove a potentially cancerous growth, after initially being forced to postpone concerts due to health issues. The surgery and possible follow-up medical treatment will likely force her to cancel her 2016 Unbreakable tour dates. Despite this medical setback, 49-year-old pop icon is remaining positive. Janet said she knows that with prayers and her will, she?ll be back out on the road in the spring or early summer.
