One of Chicago Med‘s own is sharing their personal health battle: star Marlyne Barrett with her uterine and ovarian cancer diagnosis. The actress opened up about the diagnosis to People, revealing that doctors discovered a football-sized tumor on her uterus and left ovary in July. Currently, Barrett has been undergoing “aggressive” chemotherapy while still working on the beloved Chicago-based procedural on which she plays Maggie Lockwood. Despite the treatment regiment, the illness hasn’t had any impact on the actress’s ability to appear on the Dick Wolf medical drama. As she goes through these treatments, Barrett is preparing to undergo an eventual hysterectomy.
