First receiving a diagnosis of stage 2 throat cancer, Big Ang–whose real name was Angela Raiola–later learned she had stage 4 lung and brain cancer. She admitted while a guest on Dr. Oz that she believed a lifetime of smoking gave her lung cancer. The episode on which she appeared aired just two days prior to her death.

“I was smoking for 40 years,” Big Ang told Dr. Oz. “I think whoever smokes should quit, and if they didn’t start, don’t start.”

Dr. Oz shared his dismay over her passing via Twitter.
