there's new hope in the fight against cervical cancer...
preliminary research shows a cervical cancer vaccine may be able to kill cancerous cells.
this is different from vaccines like gardasil that teens get. those prevent cancer-causing HPV infections.
this experimental treatment targets pre-cancerous lesions and cancer cells that have already formed.
more studies need to be done... this one included just 18 women. a majority of cervical cancers are caused by HPV.
