Martin Sheen compares Charlie's problems to cancer

Substance abuse and psychological problems can often be traced, in part, to relationships within the family. For that reason it's often best to bring the family together with the troubled person for regular family therapy sessions. Of course, this depends on how well the troubled person gets along with people in his/her family. Educating family members about the nature of the problem and the way to treat it can speed recovery and help prevent relapses.

The elder Sheen says his son is "doing well" after entering rehab following reported partying and a trip to the hospital for abdominal pain.

"We pray for him," Sheen said of his son on U.K.'s Sky News. "If he had cancer, how would you treat him?"

He added, "This disease of addiction is a form of cancer. You have to have an equal measure of concern and love and lift him up."

"Two and a Half Men" is currently on hiatus while Charlie recovers.
