"Lorna discovered in March that her cancer has returned," a close source to the star told The Enquirer.
"This could be a major blow to Liza's struggles."
Luft, 62, was first diagnosed with Stage 2 breast cancer in 2012. She opted for a lumpectomy and completed six rounds of preventative chemotherapy in 2013.
