The Coulier Family’s Tragic Connection to Cancer

The story of Arlen Coulier is inextricably linked to a deeply personal and tragic health history within the Coulier family, a narrative that has gained significant public attention in the last few years due to Dave Coulier's own diagnoses.

More recently, Coulier revealed a second, unrelated cancer diagnosis: tongue cancer. His openness about his treatments and his family's history with the disease—which began with his mother, Arlen—has turned him into an unintentional but powerful advocate for early detection and awareness.
