Nanoparticles Annihilate Prostate Cancer

This article discusses the possibility of using nanoparticles to fight prostate cancer. Modern chemotherapies attack tumors with the equivalent of a machinegun approach: cover the area widely with deadly fire and hope to destroy the tumor with a minimum of collateral damage. Doctors have long sought a way to precisely target tumors with their chemical therapies. Now researchers may have found it in a nanoparticle laced with a cancer-combating drug. Omid Farokhzad of Harvard University, who was conducting the test said that, "A single injection of our nanoparticles completely eradicated the tumors in five of the seven treated animals and the remaining animals had significant tumor reduction compared to the controls." Further tests will be needed to ensure that the nanoparticle is safe in animals and, eventually, in humans afflicted with prostate cancer.
