(CNN) - Actor Ryan O'Neal is recovering at home after treatment for stage 2 prostate cancer.
O'Neal's publicist said he had the treatment Thursday and that the 71-year-old is "in great spirits and very upbeat."
The star was previously treated for leukemia, which has been in remission for 11 years. He also recently had skin cancer removed from his nose.
O'Neal had been on a book tour promoting his new memoir "Both of Us" about long-time love, actress Farrah Fawcett.
She died from cancer in 2009.
