Elvis Costello has had to cancel the rest of his European tour dates to recover from surgery for a “very aggressive” form of cancer.

The singer-songwriter, born Declan Patrick MacManus and whose father is of Irish descent, released a statement on his website apologizing to his fans for canceling the concert dates.

“Six weeks ago my specialist called me and said, 'You should start playing the Lotto'. He had rarely, if ever, seen such a small but very aggressive cancerous malignancy that could be defeated by a single surgery.

Costello initially continued touring after the surgery, but after his June 24 show at the Edinburgh Playhouse, was forced “to now accept that it is going to take longer than I would have wished for me to recover my full strength.”

Show dates have been canceled in Manchester, Pula, Graz, Vienna, Tysnes and Rattvik.

He went on to promise “a magnificent new record” with his band, the Imposters, coming in October.

Costello ended his statement with a warning to his fans.

“Take very good care of your loved ones but Gentleman, do talk to you friends - you'll find you are not alone - seek your doctor's advice if you are in doubt or when it is timely and act as swiftly as you may in these matters. It may save your life. Believe me, it is better than playing roulette."
