Munn, 45, revealed her diagnosis of bilateral breast cancer in March 2024, describing it as a shocking turn of events. Remarkably, she reported having experienced no symptoms prior to her diagnosis and had even received a clear mammogram shortly before the discovery. Tests later confirmed that she had luminal B, an aggressive form of cancer affecting both of her breasts.
Throughout her journey, Munn expressed profound gratitude for the unwavering support of her husband, comedian John Mulaney. She recounted how he attended every single doctor’s appointment by her side. “There’s no better person in the world to me than my husband,” Munn stated, underscoring the importance of his presence during a time of uncertainty and fear.

Mulaney, who is known for his sharp wit, brought some levity to their challenging situation. Munn shared that he would often take notes during appointments, jotting down humorous thoughts about their experiences, including her cancer treatment and hormone therapy. “Having the humour to go through it and having someone who is so funny, it really lightens everything,” she explained, emphasising the comfort laughter can bring, even in dire circumstances.
The actress also spoke about the daily challenges they faced as a family during this period. She described how Mulaney balanced his responsibilities as a devoted father to their children, Malcolm and Méi, while ensuring he was consistently there for her. Munn detailed the juggling act he performed, saying, “I don’t think he had a moment to himself,” highlighting his selfless dedication during their toughest times.
Currently, as Munn continues to navigate the long-term effects of her breast cancer treatment, she remains committed to raising awareness about the disease. She passionately advocates for the Lifetime Risk Assessment test, an online questionnaire designed to help women assess their risk of developing breast cancer. “Knowing that it’s really changed so many people’s lives, it’s been the most amazing thing,” Munn said, expressing her desire to use her platform for good.
In her reflections, Munn acknowledged how these experiences have reshaped her outlook on life. “It’s not the Christmases and the birthdays and the New Years that we remember,” she shared. “Life happens on a Tuesday. Like, it just happens. And you cannot expect it. And so every day, you should just be so present and grateful.” These sentiments about cherishing “little moments” resonate with many, serving as a reminder to remain mindful and appreciative of everyday life.
Despite the chaos of her circumstances, Munn conveyed a sense of gratitude. “I’m so lucky that I’m in this chaos, and that I haven’t slept in a few days, and that I’m exhausted,” she said. “It’s a true privilege to just be alive in the world.” Her words highlight a heartfelt acceptance of life’s unpredictable nature, encouraging others to find joy and strength in even the smallest occasions.
As Munn continues her journey, her story serves as an inspiring reminder of resilience, love, and the importance of looking after one’s health. With her husband by her side, she is not only battling cancer but also illuminating the path for others to follow, encouraging them to prioritise their health and embrace life with gratitude.
