Amanda Peet reveals she was diagnosed with breast cancer

Amanda Peet wrote a New Yorker essay saying she was diagnosed with breast cancer after routine monitoring and subsequently had a lumpectomy and radiation; the diagnosis unfolded alongside the deaths of both her parents.

Amanda Peet has written an essay in The New Yorker about receiving a breast cancer diagnosis while both of her parents were in hospice. She describes long-standing monitoring for dense breast tissue, a biopsy in August 2025 after an abnormal ultrasound, and follow-up imaging that identified two masses in the same breast. One of the masses was found to be benign; the malignant finding was treated with a lumpectomy followed by radiation. Peet also recounts how the medical events overlapped with her family bereavement. Key details: - Peet said she had been told for years that her breasts were "dense" and had been seeing a breast surgeon every six months for checkups. - In August 2025 a biopsy was performed after an ultrasound concern; receptor testing was reported as showing favorable features that suggested a treatable form. - A second mass was identified on imaging and an MRI-guided biopsy returned benign results; she underwent a lumpectomy and then radiation rather than chemotherapy or mastectomy. - The diagnosis and treatment process coincided with both parents being in hospice care; she was present at her mother’s final moments and experienced her father’s death earlier in the timeline. Summary: Peet reports that routine monitoring led to a biopsy and subsequent treatment with lumpectomy and radiation, and that she later received a clear scan in January as she arranged for her mother’s care. The essay frames the medical course alongside the emotional context of losing both parents. Undetermined at this time.
