Scientists identify factors responsible for skin cancer growth
London: In a revolutionary study, researchers have discovered what makes skin cancer grow – a finding that could lead to new ways to prevent the disease from spreading.
Although skin cancer is easily treated when caught early, it usually becomes fatal if it spreads to other parts of the body.
Dr Lesley Walker, Cancer Research UK’s director of information, says the findings will provide “new approaches for cancer therapy”.
Scientists made the breakthrough in a study of people with a severe type of the skin-blistering disease called Epidermolysis Bullosa Simplex.
It is known that people with that particular strain are more at risk of getting a skin cancer called basal cell carcinoma – but were not sure why.
For the study, researchers at Cancer Research UK’s cell structure group at the University of Dundee compared cells of people with EBS to those without.
When the EBS cells were damaged – or rubbed enough to cause blistering – their structure changed to stop them dying.
The study found that when damaged cells continue to grow, it causes a process that allows a greater number of tumours to grow.
“Even slight damage to the skin of people with EBS can kick-start a signalling pathway which prevents the skin from killing and clearing damaged cells,” the Daily Express quoted Dr David Russell, Cancer Research UK scientist and the study’s lead author, as saying.
“Keeping these cells alive may be the body’s way of preserving the protective ‘barrier’ function of skin. But we have shown that it may also cause cells to turn cancerous which could explain the increased incidence of basal cell carcinoma in EBS individuals,’ he added.
The study has been published in Journal of Investigative Dermatology .
