Two men have been cleared of deadly skin cancer using genetically modified versions of their own immune cells.
The US National Cancer Institute team in Bethesda has also shown it can manipulate immune cells to attack breast, liver and lung cancers.

The success ratio is low, but it seems to be a promising start.
For Mark Origer, 53, the treatment completely eliminated his skin cancer and another tumour on his liver shrunk enough that it could be removed surgically.
Another man, aged 39, was able to clear the cancer that had spread to his liver, lymph nodes and lung.
