Julie Walters is opening up about her cancer diagnosis, and how it completely changed her perspective! In a recent interview with BBC's Victoria Derbyshire that aired Thursday, Walters revealed that she received the surprising diagnosis 18 months ago. 

She explained that while she was filming The Secret Garden, doctors happened to find an intestinal abnormality following a CT scan. It was that abnormality that turned out to be stage 3 colorectal cancer, more commonly referred to as bowel cancer. "I was still thinking, ‘That’s ridiculous, he must have made a mistake’. I couldn’t believe it,” Walters shared.

As of now, Walters is doing "really well", with her cancer having gone into remission. She shared that "she just had a scan and knows [I'm] clear". Still, the experience has made her think differently about her career. "I certainly don’t think I can go back to [working] six days a week, five in the morning till seven o’clock at night," she admitted.

That's because Walters says her thoughts on acting have "completely changed" since her diagnosis. She reveals that it came as a relief to her to take a break from the "merry go-round" of constant work. "I was due to do two big series… and there were two films," Walters shares. "And I just didn’t have to do any of it. And that was wonderful".
