Doctors have told Douglas there is an 80-percent cure rate for his cancer, and that he will learn in January if his ailment has been eliminated.
Douglas said the cancer has brought him closer to his father, Kirk Douglas, with whom he had a strained relationship with in the past. He also said his tense relationship with his father may have affected his relationship with his own son, Cameron Douglas, who was recently jailed on drug-related charges.
In the interview, he remains optimistic about his recovery and said while the disease shook his perspective on mortality, it showed him important lessons about family and love.
