A persistent gap exists in realizing practical, scalable solutions for affordable methods for the early detection and treatment of the major cancers in LMICs. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.
