Amanda Peet Provides Positive Health Update Following Her Breast Cancer Diagnosis

Amanda Peet provided a positive update on her health following her breast cancer diagnosis.

During a Tuesday, March 31, appearance on Watch What Happens Live With Andy Cohen, a fan question enquired as to how the Your Friends & Neighbors actress, 54, was feeling.

“Well thank you Eric, I’m doing great,” Peet told Cohen, 57, in response to the question. The fan also quizzed Peet, who revealed her 2025 diagnosis in a New Yorker essay published on March 21, on valuable advice she’d received as a result of her diagnosis.

“The best piece of advice, I would say, is ‘Enjoy it while we’re here,’ Peet responded, to which Cohen agreed before adding, “That is something to live by every day.”

Peet’s essay detailed that she was informed of her diagnosis “last fall” after undergoing what she had presumed would be a “routine scan” that examined her breast health. “For many years, I’ve been told that I have ‘dense’ and ‘busy’ breasts — not as a compliment but as a warning that they require extra monitoring,” she wrote before revealing that her physician “didn’t like the way something looked on the ultrasound.”

After undergoing a biopsy, Peet recalled how her sample was walked over and hand-delivered to a pathology department for review. “That’s when I knew,” Peet wrote, noting that her doctor shared news of her stage 1 breast cancer results the following day. “The tumor ‘appeared’ to be small, but I would need an MRI after the holiday weekend to determine ‘the extent of disease.’”

The MRI showed a second mass that was ultimately benign, which meant that Peet was not advised to undergo a double mastectomy or chemotherapy. “I would only need a lumpectomy and radiation,” she wrote. Once her radiation course had completed, Peet returned a clear scan in January.

Later that month, Peet’s mother, who was in hospice care, died.

Tragically, Peet’s father died in 2025 amid Peet’s cancer ordeal. She reflected on the time in her essay, writing, “As soon as my dad’s corpse was out of sight, I was free to panic about my cancer again.”

In an interview with E! News, published on Tuesday, March 24, Peet opened up about sharing her diagnosis with her children. (Peet and husband David Benioff, the cocreator of Game of Thrones, share daughters Frances, 19, and Molly, 15, and son, Henry, 11.)

“They’ve been great,” she told the outlet. “I definitely had to get myself together before including them. The hard part was realizing that nothing is certain and there was going to be no perfect time to tell them.”
