A statement on her website said she was undergoing surgery "to alleviate the current issues with her throat". "As a result, doctors have ordered her to rest her voice and completely recuperate before looking to schedule any work commitments," it said.

Adele cancelled her 10-date US tour earlier this month after being diagnosed with a vocal cord haemorrhage. The singer had been due to perform six dates in the UK next month, which had been postponed from September after she suffered from a severe cold and chest infection.
The singer wrote on her website earlier this month that she was "heartbroken and worried" by the ongoing problems with her voice. "I have absolutely no choice but to recuperate properly and fully, or I risk damaging my voice forever," she said.
