Lutetium-177 (Lu-177)

Lutetium-177 (Lu-177) is a radioactive isotope used in targeted cancer therapy. It emits gentle radiation that specifically attacks cancer cells while sparing surrounding healthy tissue. In medical treatments, Lu-177 is attached to molecules that seek out cancer, such as in neuroendocrine tumors or prostate cancer. Once it reaches the tumor, the radiation destroys cancer cells from within, providing an effective and localized treatment option. Its precision and relatively low side effects make Lu-177 a valuable tool in modern radiotherapy.
