Miriam González, a 35‑year‑old woman from Spain, was diagnosed with a breast tumor that behaves like two distinct diseases at the same time. No existing clinical guideline addresses a case like hers. An international team of researchers spread across three countries is using artificial intelligence to analyse all of her medical data. Every piece of data has been placed in the public domain. The goal is to design a treatment that is customized solely for her condition. The project also hopes to create a pathway for other patients whose illnesses do not fit standard protocols.
