Molecular biologists have taken nanoparticle-sized spheres and used them to deliver a cell-killing toxin from bee venom to tumors in mice, substantially reducing tumor growth without harming normal body tissues. Nanoparticles are known to concentrate in solid tumors because blood vessels in tumors show "enhanced permeability and retention effect" or EPR. Hence substances such as nanoparticles escape more readily from the bloodstream into tumors and the generally poor drainage of lymph from tumors further helps trap the particles in tumor tissue.

Would this be a reduction of cancer risk, correction of cancer gene or destruction of cancerous tissue? I think destruction of cancerous tissue but also see significance in correction of cancer gene.
