Sponge offers hope of 'less toxic' chemotherapy
Scientists believe they may have found a way to make cancer chemotherapy treatment less toxic to the body. They have begun testing a tiny sponge that sits inside a vein and removes excess chemo drugs from the blood once they have attacked the target tumour. Experts say the early work, in the journal ACS Central Science , offers hope of avoiding treatment side-effects, such as hair loss and nausea. So far, it has been tried in pigs, but researchers want to test it in people.
