UCLA (University of California, Los Angeles) scientists have developed a process for targeting cancer cells that could eliminate some of the worst side effects of chemotherapy.
Chemotherapy is the general term for any treatment involving the use of chemical agents to stop cancer cells from growing.
Normally in chemotherapy, the drugs are delivered to the whole body and attack healthy cells as well as the cancerous ones, which can be devastating to cancer patients.
This new technique deploys nanoscale, light-activated containers filled with cancer-fighting drugs throughout the body. These containers release the drugs only when targeted by a special laser, allowing scientists to confine treatment only to desired areas of the body.
