Wilder was married to Saturday Night Live actress Gilda Radner from 1984 until her death from ovarian cancer in 1989.
Since the death of Radner, Wilder has remained active in promoting cancer awareness and treatment. He is the co-founder of Gilda`s Club, a support group to raise awareness of cancer. One branch of Gilda`s Club is in Wilder`s hometown of Milwaukee. In 1998 he collaborated on the book "Gilda`s Disease" for which he shared personal experiences of Radner`s struggle with ovarian cancer. Wilder himself was hospitalized with non-Hodgkin lymphoma in 1999 but confirmed in March 2005 that his cancer was in complete remission following a stem cell transplant and chemotherapy.
