The Stay With Me hitmaker has cancelled a string of global tour dates, including concerts in Australia, Japan and the Philippines, after he was diagnosed with the condition.

Smith announced earlier this week (beg04May15) that he was jetting to America to visit a specialist and on Thursday (07May15), he announced he is set to have an operation which will leave him out of action for up to two months.

In a post on the star writes, "Dear all: I am very upset to announce I have been battling to get my vocal cords better the last 10 days but unfortunately they haven't recovered and I am going to need surgery. I'm so gutted to be missing all the shows and events I was meant to be playing at. The doctors say I will be back in 6-8 weeks and I cannot wait to sing for you all soon.

"Bad news. I have my operation booked for next week, so getting really nervous. But by doing this in 8 weeks time I'm gonna be able to sing like never before so it's worth it. I am so sorry to all. Dreading the next month thou (though), I can't speak for three weeks after the op (sic)".
