Actress Constance Zimmer Announces She Is Cancer-Free After Three Surgeries

Zimmer said she received the diagnosis on March 13 while away from home, hearing it from her doctor over Zoom; she then called her husband and returned home to tell their daughter in person.
DCIS is a condition in which abnormal cells are contained within the milk ducts and have not spread into surrounding tissue, according to the article explaining Zimmer’s diagnosis.
Zimmer said she and her Talk Fifty To Me co-host Heidi planned to discuss her experience with breast surgeon Kristi Funk on the podcast, with the episode scheduled for October 6.
Zimmer’s daughter is Colette, whom she shares with her husband, Russ Lamoureux.
Actress Constance Zimmer is cancer-free after undergoing three breast surgeries in three weeks. UNILAD reported that the 55-year-old star, known for her roles in "Entourage" and "Love Story," was diagnosed with Stage 0 breast cancer (ductal carcinoma in situ) in March 2026. She kept the diagnosis private while receiving treatment and is now sharing her story during Breast Cancer Awareness Month to encourage early screening.
Zimmer received her diagnosis on March 13 while traveling, hearing the news from her doctor over a video call. Yahoo News reported that she immediately called her husband, Russ Lamoureux, then returned home to tell their daughter Colette in person. She described the moment as overwhelming, experiencing what she called "pure shock and fear."
Rather than accept multiple doctors' recommendations for a full mastectomy, Zimmer chose a lumpectomy with breast surgeon Kristi Funk. Head Topics reported that she underwent three separate surgeries over three weeks to remove all cancerous tissue. After the surgical procedures, she completed a course of radiation therapy to eliminate any remaining cancer cells.
Ductal carcinoma in situ (DCIS) is a precancerous condition where abnormal cells grow inside the milk ducts but have not spread into surrounding breast tissue. UNILAD explained that this early-stage diagnosis means the cancer was caught before it could become invasive. Early detection through regular screening made Zimmer's successful treatment possible.
Zimmer kept her diagnosis secret while promoting FX's "Love Story: John F. Kennedy Jr. & Carolyn Bessette-Kennedy" and receiving an Emmy nomination. Yahoo News noted that she managed her treatment privately during a demanding public schedule. Now cancer-free, she plans to discuss her experience with co-host Heidi on their "Talk Fifty To Me" podcast on October 6.
