Beloved British actress Lynda Bellingham has been diagnosed with cancer. The 65-year-old was due to tour the U.K. as the star of Kay Mellor's play A Passionate Woman, but has postponed her appearances to receive treatment. Bellingham, who is perhaps best known for her role as Helen Herriot in BBC drama All Creatures Great and Small, did not divulge any further details surrounding her condition. A statement from the actress reads: "I'm devastated not to be able to honour my commitments to the play this year. But having toured many times before, I'm aware of the sheer stamina needed and I need to prioritise my recovery. That said, nothing's going to stop me coming back next year, and I can't wait to be 'a passionate woman'." The tour of A Passionate Woman was scheduled to begin at the Sheffield Lyceum in September (13).
