How Amanda Peet’s children reacted to her cancer diagnosis
Speaking to E! News, Amanda said she immediately leaned on friends and family. Telling her children, Frances, 19, Molly, 15, and Henry, 11, first took a moment to gather herself. “They’ve been great,” he said, but admitted there’s never a good time for that kind of conversation. “It was hard to realize that nothing is certain and there would never be a perfect time to tell them.”Amanda explained in her New Yorker essay that the cancer is hormone receptor-positive and HER2-negative, which means it’s less aggressive and usually easier to treat. She only needed a lumpectomy and radiation, not a double mastectomy. He is grateful that his children are there with him, even though they are still children. They keep him grounded, sometimes completely surprised.He laughed trying to show Something’s Gotta Give, the movie he made with Jack Nicholson and Diane Keaton. Her children lasted about five minutes before it turned off. “They were saying, ‘This is reprehensible. This is ethically questionable, and we’re out.’ But things change. Now her daughters break into her closet and steal her clothes. “For so long, it was, ‘What are you wearing, Mom? Why are you so cool?’ And then, all of a sudden, I was like, ‘Oh, I looked at you. Look who’s coming into my closet’”.
Amanda Peet’s Cancer Diagnosis: What Happened?
Amanda shared even more in her essay. She was diagnosed with stage 1 breast cancer in the fall of 2025, when both of her parents were dying in different hospices in different parts of the country. Over the years, doctors told her she needed extra monitoring, so she saw a breast surgeon every six months. According to her New Yorker piece six months ago, she had what she thought was a routine scan, but her doctor didn’t like the look of something on the ultrasound and wanted a biopsy. After that, his doctor said he would personally take the sample to Cedars-Sinai Pathology. “Then I knew,” Amanda wrote.They found a small tumor and needed an MRI to see how far it had spread. While doing his tests, his father’s health took a turn for the worse. He ran to New York, but didn’t make it in time to say goodbye. When she returned to LA, her doctor called with the results: HER2-negative breast cancer.Now, according to the Mayo Clinic, HER2-negative breast cancer occurs when breast cancer cells do not have high levels of the human epidermal growth factor receptor 2 (HER2) protein, which fuels cancer growth.“You’d think I’d just gone into ecstasy. I was happier than I was before I was diagnosed,” Peet said. “But about ten minutes later, it hit me: I still needed an MRI, and the old panic returned. Dr. K told me the radiologist would look at my lymph nodes and look for something unexpected on the left side. That’s when I realized: cancer doesn’t announce itself all at once. It comes in drops.”Peet said the radiologist “saw no evidence of lymph node involvement,” however, they found a “second mass” in the same breast and ran more tests to look at the cells. He added that the results showed that the second mass was “benign” and that she had stage I breast cancer, which “required a lumpectomy and radiation, not a mastectomy or double chemotherapy.”When she learned the second tumor was not cancerous, she and her husband, David, decided it was time to tell their grown daughters, Frances and Molly June.“My therapist told me I didn’t have to act tough or pretend I had all the answers,” Peet said, recalling what it was like to talk to her children. “She said I’d be surprised how much the kids can handle, and that asking for help would really make them feel useful.” Molly shouted. Frankie, FaceTiming from her college quad, covered her mouth and sat there, taking it in. He didn’t budge until he realized the bright side: It looked like I was stage I and wouldn’t need chemo.After much anxiety and fear, Amanda revealed that she finally got her first clear scan in mid-January.
