This article discusses recent findings explaining the formation of skin tumours where the skin has been damaged by physical injury. Scientists have suggested that mutations in stem cells may be responsible. Following injury (which may be something as tiny as a papercut) these mutated stem cells migrate towards the skin in order to repair the damage, however whilst in the lower layers of skin, the stem cells disrupt a biochemical signalling pathway which has been linked to basal cell carcinoma development. I thought this article revlevant to Dr Meacock's lectures in #MB1005 and #BS1005, whereby he discussed how mutations in cells can lead to the development of cancer. - Kelly Barnett from Bookmarklet
