The procedure took place on Dec. 23, and marks his second brush with throat cancer. Angélil was previously diagnosed with the illness in 1999, at which time Dion briefly retired from music to help take care of him.
The singer, who has been performing semi-regular shows in Las Vegas since 2011, says she is making sure that her husband puts his health first. "I don't want René to stress out with work-related issues," Dion said in a statement. "I want him to focus on getting back to 100 percent. I've been doing my shows at the Colosseum and everything's under control."
Dion and Angélil have been married since 1994 and have three children together, René-Charles, 13, and 4-year-old twins Eddy and Nelson. "At hom,e we've been spending a lot of quality time with the family," she said. "We feel very fortunate that we've been able to get the best care possible and we thank God every day for helping us get through this ordeal."
