The findings, published in the Journal of Experimental Medicine, rev

Nerves (in green) within a melanoma tumour. Photo by: Dr. David J. Simon Nerve fibres within melanomas can slow tumour growth, according to a study led by Weill Cornell Medicine investigators. The findings help clarify the emerging field of cancer neuroscience and may inform future therapeutic strategies. In the study, published April 29 in Neuron, the researchers used mouse models of melanoma to examine the presence and the effects of peripheral nerves that grow into tumours
