Billy Baldwin reveals his teen son's battle with cancer

Billy Baldwin’s 17-year-old son with wife Chynna Phillips has been quietly battling cancer for the last year. The “Backdraft” actor and brother of Alec Baldwin revealed the news on Instagram Thursday — one year after Vance’s diagnosis. He said their family “kept it very quiet” as the teen went through “28 rounds of chemo.” Vance wrote in his own post that he’s “been clear” of cancer “for months now.”
