Amanda Peet Reveals She Was Diagnosed with Breast Cancer While Both of Her Parents Were in Hospice

Actress Amanda Peet has opened up about her personal battle with breast cancer, sharing her experiences in a heartfelt essay published in The New Yorker. Following her diagnosis in the autumn of 2025, the 54-year-old star faced an incredibly challenging period, as both of her parents were gravely ill and receiving care in separate hospices.

Peet revealed that she had been undergoing regular check-ups for her breasts due to previous concerns flagged by medical professionals. For years, she had attended biannual visits with a breast surgeon, which led to her fearing a potential diagnosis. It was during a routine scan just before Labor Day that her worst fears materialised. After noting something concerning on the ultrasound, her doctor performed a biopsy, which ultimately confirmed the presence of a small tumour in her breast.

Amid this turmoil, Peet’s family was in disarray. Her parents were battling their own health issues on opposite sides of the country, with her father’s condition worsening shortly after her initial tests. Tragically, she arrived in New York only to learn that he had passed away before she could say goodbye.

Following her father’s death, Peet returned to Los Angeles, where she received a phone call from her physician with the results of her pathology tests. Learning that her breast cancer was classified as HER2-negative brought her unexpected relief. HER2-negative breast cancer means that the malignancy lacks high levels of the HER2 protein, which is known to promote the growth of cancer cells.

This initial sense of relief was quickly tempered by the realisation that further tests were still necessary. Peet recounted experiencing a fleeting moment of joy that quickly gave way to anxiety as she awaited an MRI to assess the extent of her condition. The ensuing tests revealed a second mass in her breast, prompting additional examinations.

Fortunately, subsequent results indicated that this newly identified mass was benign, and she was diagnosed with stage I breast cancer. Peet embraced a treatment plan that incorporated a lumpectomy and radiation, circumventing more invasive procedures like chemotherapy or a double mastectomy.

Once reassured that her prognosis was manageable, Peet felt it was time to share the news with her children. Alongside her husband, David Benioff, she approached their daughters, Frances and Molly June, with the updates. Their therapist had advised Peet to be honest about her condition, suggesting that children often rise to the occasion when confronted with familial challenges. Molly was devastated upon hearing the news, while Frances, attending university at the time, reacted with disbelief, covering her mouth in shock until she processed the positive aspects of the situation.

The Peet-Benioff family, which also includes their son Henry, has navigated the emotional impact of these developments together. Peet described the experience as both nerve-wracking and ultimately unifying for the family.

In mid-January, Peet celebrated a significant milestone: her first clear scan after treatment. However, just days later, she faced further heartbreak with the passing of her mother, who had been suffering from Parkinson’s disease. This juxtaposition of relief and sorrow marked a profound period of change for Peet, who continues to process the complexities of her journey with cancer while grappling with loss.

Peet’s candid account not only highlights her personal experiences but underscores the importance of family and support during times of hardship. Her story serves as a reminder of the resilience many demonstrate in the face of life-altering challenges.
