British author Christopher Hitchens says he must undergo chemotherapy on his esophagus and has canceled some engagements.
The 61-year-old Hitchens, whose most recent book, "Hitch-22," is on Publishers Weekly's best-sellers list, posted a message on his publisher's website that he had been told by his doctor that he must undergo a course of chemotherapy. Hitchens expressed regret for having to cancel engagements on short notice.
His publisher issued a statement saying the author was being given his privacy during the treatments.
The author, essayist and columnist lives near DuPont Circle. He has written more than a dozen books and enjoyed surprising commercial success three years ago with "God Is Not Great," a direct attack on religion.
