Dark skin skin men are more likely to have dog skin cancers, according to a study published in the journal Epidemiology.
Researchers from the University of Birmingham and King’s College London looked at the prevalence of cancer among 5,744 white British men aged between 50 and 74.
They found that dark skinned men were 2.3 times more likely than white men to have a dog skin tumour, and 5.8 times more than white women to have one.
Researchers believe this could be due to a combination of genetics, lifestyle, and lifestyle-related factors.
Dr J. Robert Evans, lead author from the study, said: ‘We’ve known for some time that dark-skinned men are at a higher prevalence of skin cancer.’
We have to understand that there is something about dark-skinned men who are living in colder climates that predisposes them to developing a tumour.’
If we are able to identify the genes that cause this, we can hopefully develop treatments for the skin cancer.’
In this case, dark-skins men are the ones who appear to be at a greater risk of having a tumours.
The study was part of a larger study looking at how the risk of skin cancers varied by skin colour.
The researchers analysed the results of the UK’s Health Survey of Skin Cancer in 2012 and compared them to those from the Cancer Research UK survey in 2010.
They found that those with darker skin were more likely (in the UK) to have had a tumoured skin, compared to those with lighter skin.
The authors concluded: ‘Dark skin is associated with an increased risk of developing skin cancer in men, as is lighter skin, but the exact mechanisms underlying this association are not well understood.’
Dark skin men also had more aggressive tumours, with a greater number of tumours located on their neck, stomach and back compared to the light-skinned.
Dr Evans added: ‘It may be that dark or lighter skin colour predisposes people to having tumours on the neck, chest, back and abdomen.’
Tumours are associated with the increased risk that they will be more aggressive and cause scarring.’
It is important that we identify these tumours early and treat them before they spread and cause problems.’
