Dr. Steven Zeitels, a renowned Boston-based throat surgeon, confirmed yesterday that British pop soul singer Adele is his patient and that he’s treating her for a singing-related injury. ‘‘Her people wanted me to talk to you,’’ Zeitels said. ‘‘They wanted to make sure that the truth was out there. There have been crazy and unfortunate rumors — that she’s being treated for cancer, for example. I can tell you that is absolutely not true. To be blunt, her throat is bleeding. It’s a common condition among singers. But it is not career-ending. It is not the most serious. And in her case it can be fixed with surgery. And I will be performing that surgery on Adele at some point in the future. I believe she will be just fine.’’ While Zeitels, the Eugene B. Casey Professor of Laryngeal Surgery at Harvard Medical School and the director of the Center for Laryngeal Surgery and Voice Rehabilitation at Massachusetts General Hospital, would not say directly whether Adele was currently in Boston, he did reiterate, while describing her ailment, that ‘‘the reason she is here is for treatment for bleeding in the throat.’’ Adele recently canceled her tour due to throat injuries.
