Amanda Peet, 54, thought she had a clean bill of health after an MRI, but doctors were quietly watching the 'weird' change she had felt in her skin. Six months later, a routine scan led to a breast cancer diagnosis that began without a lump.

Peet, who was diagnosed last fall, recalled that she was in her closet when she noticed something that 'just didn't feel like normal skin'. She said it was not the 'frozen pea' often described as a breast cancer lump when she appeared on Today.

An MRI followed, but she was sent away believing she was in the clear. In reality, her doctors were watching the area, she said, and the change was not forgotten.

On the Friday before Labor Day in 2025, Peet went in for what she thought was a routine scan. Her doctor spotted something concerning on the ultrasound and performed a biopsy, she wrote in an essay.

She knew something was wrong because her usually chatty physician went silent. The doctor also said she would hand-deliver the sample to Cedars-Sinai on a Friday night, another concerning clue.

Skin Changes That Warrant Attention

Cleveland Clinic lists skin changes such as dimpling, bulging, puckering or redness among breast cancer symptoms. It adds that they are particularly notable if seen in a mirror with the arms raised overhead.

The clinic also encourages people to learn how their breasts normally look and feel so they can notice changes. It says 8 out of 10 breast lumps are non-cancerous, but that treatment is more successful when started early.

Susan G. Komen adds swelling, warmth and darkening of the breast to its list of warning signs. It advises anyone who notices a change in the breast or underarm area to see a doctor to be sure it is not breast cancer.

The organisation also says any lump or change that feels different from the rest of the breast, or from the other breast, should be checked. Feeling something different from what was felt before is another cue to seek advice.

Breastcancer.org says skin with a texture like an orange peel is another change worth reporting, along with itchiness, scaling and a newly inverted nipple. A change in the shape or size of the breast should also be reported.

Lobular Cancer Is Hard To Detect

Peet said she will never forget the call that delivered her diagnosis soon after. Her cancer was hormone-receptor-positive and HER2-negative lobular breast cancer, and it was caught early, at Stage 1.

The National Cancer Institute says lobular carcinoma accounts for 10% to 15% of all breast cancer cases. The website says lobular breast cancer tumours do not usually form a distinct lump, making them harder to detect, particularly in women with dense breast tissue.

The website adds that invasive lobular carcinoma is an uncommon type of breast cancer that is less likely to form a lump than other breast cancers. Its cells tend to grow in diffuse, unconnected lines rather than forming a distinct mass, which can make the cancer harder to detect.

Anne Peled, MD, co-director of the Sutter Health California Pacific Medical Center Breast Cancer Program in San Francisco, says many early-stage cancers form no lump at all. Others, she said, produce lumps too small to feel.

Peet has dense breasts and had been seeing a breast surgeon every six months for check-ups. She also underwent a lumpectomy and radiation.

Peet said she thinks about how lucky she was in so many ways. She noted that she had great insurance and strong support from friends and family, and that not everybody has that.
