Williams joked about his own experience to put everyone in attendance at ease.
"People have scolded me a little bit for faking a cancer scare to try to get more people at the breakfast," he said.
The fundraiser breakfast actually had its largest crowd on record, with 450 people attending to raise money for cancer research.
"It was a wild time in the Williams family for about 24 days and it was something," Williams said about having tumors removed from his kidneys last month. Not knowing if they were cancerous, the coach told the crowd he was scared to death.
"I was the biggest dagum pansy you've ever seen and the surgery scared the dickens out of me, but Dr. Wallen and his team was just sensational," he said.
Williams' team of doctors and others from the UNC Lineberger Comprehensive Cancer Center were at the breakfast, along with volunteers and donors. Some of them even bid $7,000 on two Williams replica jerseys.
Though Williams said he is ready to move forward, he said he knows how devastating the word cancer can be.
"People had always told me and I'd always heard that people say that when you hear the word cancer, it changes you," He said. "It changes your life and throws everything into a swirl, and it really did."
