OTRC: Bonnie Franklin of 'One Day at a Time' has pancreatic cancer

Bonnie Franklin, who played Ann Romano Royer on the 1970s comedy series "One Day at a Time," is battling pancreatic cancer.

The show's production company, CBS, revealed the news to the Associated Press. The 68-year-old actress' family members told the network that Franklin is undergoing treatment and continuing her normal schedule.

Franklin, a native of Southern California, began her on-screen career in the mid-1950s, making her acting debut on the show "Shower of Stars." She starred on "One Day at a Time," playing a single mother, from its debut in 1975 to 1984, when it ended. Mackenzie Phillips, 52, and Valerie Bertinelli, 52, played her daughters, Julie and Barbara.

"Sending out love and sweet prayers to my 'mom,'" Phillips Tweeted on Monday, September 24. "The incomparable Bonnie Franklin."

Franklin reunited with Bertinelli on an episode of the latter actress' current series "Hot In Cleveland" in 2011. The two, along with Phillips and cast members Richard Masur and Pat Harrington Jr. then appeared together at the TV Land Awards on April 14, 2012.

Franklin's most recent on-screen gig was a small part as a nun on the CBS soap opera "The Young and The Restless." Her episode aired in August.

"I got a phone call and they said, 'You want to do Y&R?' And I said, 'Well, okay.'" Franklin said in an interview posted on CBS.com that month. "I'm at a stage in my life where I say yes to a lot of things. I've never done [a] soap before."

Franklin has also been keeping busy for more than 12 years running a theatre company called Classic and Contemporary American Plays (CCAP), made up of film and stage actors who participate in staged readings along with Los Angeles high school students.
