They say researchers believe viruses - which are experts at killing cells - could one day become a valuable addition to the medical armoury against cancer.
The latest progress has been made in a small study using MediGene AG's virus NV1020 and was presented at the annual European Society for Medical Oncology conference in Lugano, Switzerland.
NV1020 is a modified version of the herpes simplex virus, which causes cold sores.
Its genetic make-up has been altered that so it only replicates in cancer cells, killing them in the process and leaving ordinary cells alone. © 2007 Australian Broadcasting Corporation
