‘Sticky balls’ may stop cancer spreading

Cancer-killing “sticky balls” can destroy tumour cells in the blood and may prevent cancers spreading, early research suggests. Scientists at Cornell University, in the US, have designed nanoparticles that stay in the bloodstream and kill migrating cancer cells on contact. Lead researcher, Prof Michael King, said the nanoparticles could be used used before surgery or radiotherapy, which can result in tumour cells being shed from the main tumour.
