Artificial intelligence (AI) is gradually reshaping the contours of modern medicine, but a breakthrough could forever change cancer diagnosis. Indeed, the CHIEF model, developed by Harvard Medical School, has just reached a historic milestone. Capable of detecting several types of cancers with 96% accuracy, it stands out as one of the most promising tools for improving early diagnosis and prognostic assessment. In the face of growing challenges in oncology, this model opens new perspectives for cancer research and treatment.
