“Brooks went to his attorney and publicist a few weeks ago, telling them that he wanted to profit from his cancer story,” a source exclusively tells Life & Style.

His team was not aware that he had already “sold the doctored records for about $12,000,” according to the source. Brooks claims he was diagnosed with stage three non-Hodgkin’s lymphoma, and was treated at the City of Hope Hospital in LA.

When the medical documents from City of Hope were later exposed as fake, his team demanded proof of his illness from him.

“He refused and wouldn’t even confirm or deny to them whether he has cancer or ever did,” says the source. Brooks’ attorney quit after the incident.
