(CNN) Markie Post, the actress known for her roles in "Night Court" and "The Fall Guy," has died. She was 70 years old.
Post passed away Saturday, her manager Ellen Lubin Sanitsky of Wright Entertainment confirmed to CNN on Sunday.
"With great sadness, the family of actress Markie Post tonight shares her passing after a three year, ten month battle with cancer," her family said in a statement.
Post chose to continue working despite battling cancer and going through chemo treatments, "determined to make it her 'side job,'" the statement said, adding that the actress played a role in a Lifetime Christmas movie and was a frequent guest star on the ABC series "The Kids Are Alright" during that fight.
"But for us, our pride is in who she was in addition to acting; a person who made elaborate cakes for friends, sewed curtains for first apartments and showed us how to be kind, loving and forgiving in an often harsh world," her family said.
Born on November 4, 1950 in Palo Alto, California, Post launched her TV career "by working behind the scenes on game shows," online entertainment news site Deadline reported. She eventually got in front of the camera in 1979, appearing on shows including "Chips," "The Incredible Hulk" and "Hart to Hart."
Post became widely known for her roles on the popular 1980s shows, "The Fall Guy" and "Night Court" and more recent appearances in ABC's "The Kids are Alright" and Lifetime Movies.
