Billy Baldwin, Chynna Phillips reveal their teen son was diagnosed with cancer last year
Billy Baldwin is opening up about his teen son's cancer diagnosis.
The "Northern Rescue" star revealed on Instagram that Vance, his 17-year-old son with wife Chynna Phillips, has been battling cancer the past year – a diagnosis the family has kept "very quiet."
"A year ago today my son Vance was diagnosed with cancer… he was 16 years old," Baldwin, 56, wrote Thursday. "He kept it very quiet… we all did."
Baldwin said Vance underwent "28 rounds of chemo" during the last year, "yet stayed VERY positive, focused and kept his life as normal as possible... every single day."
And, Vance has "been clear" of cancer "for months now," the teen wrote on his own Instagram account on the anniversary of his diagnosis.

Baldwin described his son as a "tough son of a (expletive)" with a "heart of gold," adding that he's "never seen anything" like Vance's "courage, strength, bravery" and "attitude."
"Never been prouder," Baldwin wrote. "Love you son."
The actor also thanked everyone who "stepped up for (Vance) during this difficult time," including his teachers, coaches, friends and doctors: "Your love, kindness & support definitely helped get him/ us through."
Phillips – the 51-year-old daughter of musician John Phillips and member of the music group Wilson Phillips – responded to Baldwin's post, writing, "Our baby. Our hero."
Baldwin and Phillips, who tied the knot in 1995, also share daughters Jameson, 19, and Brooke, 14.
Earlier in the week, Baldwin and his family traveled to South Carolina for his niece Hailey Baldwin's wedding to Justin Bieber.
"So cool to get the both families & friends together for some bonding and good old fashioned par-taying!" Baldwin captioned an Instagram photo of the newlyweds. "Chynna, Jameson, Vance, Brooke & I LOVED meeting everyone!! You two are an adorable couple!!"
