Battling Cancer, Michael Douglas Visits Son in Prison Despite his grueling treatments for advanced throat cancer, Michael Douglas has been making regular three-hour trips to see his son, Cameron, in prison in Pennsylvania.

Douglas, 66, is recovering from chemotherapy and radiation. Cameron, 31, is serving a five-year drug-related prison sentence.

"Michael is still visiting with Cameron," the actor's longtime friend and publicist Allen Burry tells "He's not going every day and not as often as he would like, but he is still visiting with him."

Burry also gave a general update on the elder Douglas' condition, saying he is in good spirits. "Michael completed his treatment about three weeks ago and is recuperating from the process. No further treatments are scheduled."
