“The threat of melanoma is not in the initial tumour that appears on the skin, but rather in its metastasis – cancer cells sent off to colonise vital organs like the brain, lungs, liver and bones,” said Levy.
If caught early, the mole can simply be removed, but once it has begun to spread the procedure is more complicated and usually involves chemotherapy or radiation.
The research team say that have identified two chemicals that can inhibit the spreading process, one stops the cancer spreading from the tumour to the skin, and the other blocks the skin from undergoing changes to receive the cancer cells.
The results of the team’s research was published on Sunday in the journal Nature Cell Biology.
