CBS, the network that aired “One Day At a Time” from 1975 to 1984, said Franklin, 68, is going through treatment for pancreatic cancer and is “continuing her normal schedule,” according to a statement given to the Associated Press.
“One Day At a Time” also starred Mackenzie Phillips and Valerie Bertinelli, who played Franklin’s daughters on the long-running CBS sitcom.
Franklin’s TV daughters took to Twitter to send their prayers to the 68-year-old actress.
“Sending out love and sweet prayers to my 'mom.' The incomparable Bonnie Franklin,” Phillips tweeted.
In a Twitter message posted Tuesday afternoon, Bertinelli called Franklin “the kindest, smartest, bravest woman I know."
“Send some of your extra prayers to Bonnie please,” she wrote.
News of Franklin’s pancreatic cancer diagnosis came as the actress’ last appearance on the daytime soap opera “The Young & The Restless” aired, according to MSN Entertainment.
Others in the entertainment world also shared their thoughts on Franklin through their Twitter accounts.
Patty Duke wrote, “my heart and prayers r with Bonnie and her family.”
“Saddened to hear about Bonnie Franklin's diagnosis,” wrote actor Michael Muhney, Franklin’s “Young & The Restless” co-star.
Along with the message, Franklin tweeted a link to his page on the L.A. Cancer Challenge 2012, which he set up to raise funds for pancreatic cancer.
