Amanda Peet has opened up about a "weird" symptom she discovered before she was diagnosed with breast cancer last year.
During her appearance on Today on Thursday, October 1, Peet shared that last fall while she was changing, she observed something alarming with her body.
Amanda Peet on her symptom before cancer diagnosis
"I was in my closet, I was probably putting something on and I felt a weird — it just didn't feel like normal skin — but it wasn't the frozen pea that everybody talks about," the actress said.
She added, "I went and I even got an MRI and then they sent me away."
"So I thought I had a clean bill of health, but they were actually watching it."
Amanda Peet's cancer diagnosis
The 54-year-old said that when she went in for a routine scan six months later, her doctor told her they noticed something concerning on her ultrasound.
Following the tests, Peet's doctor called her to let her know she had lobular cancer, the second most common type of breast cancer.
"I'll never forget that moment," she recalled.
The Your Friends & Neighbors star said she originally "had such an old-fashioned notion about breast cancer".
"This is like a slow drip of information doctors are gathering — genomic, genetic information … so they can get a full picture of what the best treatment would be," she shared.
"I had no idea it was going to take so long. So if you're an anxious person, it's your basic nightmare," Peet continued.
Amanda Peet says she doesn't take medical advice from TikTok
The actress urged people to "stay off the internet" if they have been diagnosed with cancer to avoid going down rabbit holes of possible misinformation.
However, Peet said she had an "advantage" because her sister and brother-in-law are both doctors.
"I've been taught not to take my medical advice from influencers or TikTok or anybody else," she shared.
In March, Peet revealed in a New Yorker article that she had been diagnosed with cancer while dealing with her divorced parents being in hospice care "on opposite coasts".
Her mother, Penny Levy, passed away in January 2026 following a long battle with Parkinson's disease, while her father, Charles Peet Jr. died in late 2025.
The Saving Silverman actress received her first clear, cancer-free scan in mid-January after undergoing treatment.
Amanda Peet shares two daughters and one son with husband David Benioff, with whom she tied the knot in September 2006.
