Constance Zimmer kept one of the biggest secrets of her life while walking Emmy red carpets this year. The Love Story and Entourage actress has revealed she was secretly diagnosed with breast cancer in March, undergoing three surgeries while publicly promoting her Emmy-nominated role.
The 55-year-old, known for playing Carolyn Bessette’s mother Ann Marie Messina in FX’s Love Story: John F. Kennedy Jr. & Carolyn Bessette, shared the news on Instagram to mark Breast Cancer Awareness Month, which falls in October.
Zimmer said she was told over a Zoom call with her doctor on 13 March, while away from home, that she had Ductal Carcinoma in Situ (DCIS), also known as Stage 0 breast cancer. “The silence was deafening,” she wrote, adding that her first thought was to get home to tell her husband, Russ Lamoureux, and their 18-year-old daughter, Colette, in person.
She described the weeks that followed as mentally “overwhelming”, explaining that most doctors initially recommended a mastectomy as the quickest way to remove the mass. Zimmer said she wasn’t ready to accept that as her only option, writing: “What if I want to save my breast instead?”
Why it matters
Zimmer eventually found surgeon Dr Kristi Funk, who suggested a lumpectomy rather than a full mastectomy. “She was the first doctor to make me feel like what I wanted mattered,” Zimmer wrote, saying the decision reduced her to tears of relief. It took three operations across three consecutive weeks to remove the cancer while preserving her breast, followed by a course of radiotherapy.
Her story lands during a month dedicated to raising awareness of breast cancer symptoms and screening, and highlights that DCIS, an early, non-invasive form of the disease, can still require significant treatment. Zimmer said she wanted to speak out so that other women facing similar decisions “deserve to feel heard, empowered, and supported in making decisions about her own body and her own cancer care.”
Throughout her treatment, Zimmer was simultaneously on a very public press tour for Love Story, the Ryan Murphy-produced Disney+ drama retelling the relationship between JFK Jr and Carolyn Bessette, and was later nominated for an Emmy for her role in the show. She said she chose to keep the diagnosis private during that period, writing: “I then followed my surgeries with radiation, while celebrating my Emmy Nomination.”
What happens next
Zimmer confirmed she is now “cancer-free”, sharing a photograph taken by photographer Cathrine White, which she said was the first picture of her since her diagnosis. She described the past seven months as a mix of “pure shock and fear alongside pure joy and gratitude.”
Her surgeon, Dr Kristi Funk, is set to appear on Zimmer’s podcast, Talk Fifty to Me, to discuss the diagnosis and treatment in more detail.
Zimmer has built a long career in US television, with credits including Boston Legal, Entourage, House of Cards, UnREAL, Big Sky and Netflix’s The Lincoln Lawyer, before taking on her current role in Love Story.
