Scottish comedian Billy Connolly was diagnosed with the "initial symptoms" of Parkinson's disease while recently undergoing surgery for prostate cancer.

According to a statement posted on his website, the 70-year-old actor and stand-up comic "recently underwent minor surgery in America after being diagnosed with the very early stages of prostate cancer."

"The operation was a total success, and Billy is fully recovered," the statement said.

But, according to the statement, Connolly was additionally diagnosed with Parkinson's, an incurable degenerative illness which causes tremors, forgetfulness and slow movements in sufferers.

Connolly is already receiving treatment, according to the statement.

"Billy has been assured by experts that the findings will in no way inhibit or affect his ability to work, and he will start filming a TV series in the near future, as well as undertaking an extensive theatrical tour of New Zealand in the new year," the statement read.

Connolly has appeared in a number of Hollywood films, including "The Hobbit" movies, "Brave" and the 2012 film "Quartet." His role in the 1997 film "Mrs. Brown" opposite Judi Dench brought him international recognition.

Connolly joins other Hollywood actors battling the disease, including Michael J. Fox, 52, who was diagnosed at age 30, and British actor Bob Hoskins, 70, who announced his retirement after he was diagnosed last year. Singer Linda Rondstadt recently revealed that she can no longer sing because she has Parkinson's.
