Tumor Tissue via Localized Beta Emission from Radioisotope Delivery

Molecular classification
Radiopharmaceutical
01

Overview

This approach involves the selective destruction of tumor tissue by delivering beta-emitting radioisotopes directly to or near cancer cells. It is not a single molecular entity but a therapeutic strategy where the “target” is defined by selective accumulation within cancerous tissue followed by localized release of cytotoxic beta radiation. Delivery vehicles such as antibodies, peptides, or nanoparticles, guide the radioisotopes, maximizing tumor cell kill while minimizing damage to healthy tissues.
