Celine Dion has canceled her Asia tour and postponed her Las Vegas residency in order to be along side her cancer-battling husband.

Dion's husband Rene Angelil had a tumor removed from his throat last December. Dion tells People that it has been "a very difficult and stressful time."

"I want to devote every ounce of my strength and energy to my husband's healing, and to do so, it's important for me to dedicate this time to him and to our children," Dion told the magazine. "I also want to apologize to all my fans everywhere, for inconveniencing them, and I thank them so much for their love and support."

Dion canceled her entire tour of Asia that was scheduled for later this year.

The singer herself has also battled some health issues. Due to inflammation in her throat, Dion has performed her show at the Caesars Palace since July 29. She has had a residency at Caesars since 2003 and is under contract until 2019, according to Seattle Pi.

Celine, 46, and Rene, 72, have three children together. Eldest Rene-Charles, 13, and twins Eddy and Nelson, 3.
