Amanda Peet hopes sharing her breast cancer diagnosis will "create a community".
The 54-year-old actress had six-monthly checkups due to having "dense" and "busy" breasts, and she was sent for a biopsy following a routine appointment in August 2025, which resulted in a tumour that "appeared" small being found but needed a Magnetic Resonance Imaging (MRI) scan to determine "the extent of disease".
