Cancer diagnosis and treatment today is reactive, relying on snapshot monitoring methods and limited precision medicine approaches.A researcher from the University of Cambridge has developed an implantable brain-computer interface (BCI) to track and treat cancer.The BCI platform can measure cancer progression biomarkers in real-time and modulate brain function to control cancerous signaling.The aim is to conduct first human trials within the next 2 years, providing longitudinal data and complimentary therapy to standard care.
