Over the past three decades, male melanoma deaths were higher than women's deaths in 33 countries, according to the analysis presented at the NCRI's 2018 G18 cancer conference in Glasgow on Sunday. Women's prices either stabilized or declined.
The study focused on 33 developed countries in Europe, North America and Australia, as they had the most reliable data.
The researchers "wanted to carry out an updated analysis of recent melanoma mortality rates around the world to try and understand these patterns, and if new strategies for diagnosis, treatment and prevention have some effect," said Dr. Dorothy Yang, junior doctor at Royal Free London NHS Foundation Trust, who led the survey.
"In the last 30 years, mortality trends (for melanoma) have increased in most countries," Yang told CNN. "There is evidence that men are less likely to be protected from sunlight or engage in awareness and prevention campaigns for melanoma."
He added that women and men's biological differences are currently being studied to see if they also contribute to gender inequalities in melanoma deaths and stressed that this is an observational study and that more research is needed because there are differences between of the sexes in terms of mortality rates.
Increase in 32 countries
Australia and Slovenia were found to have the highest number of melanoma deaths in both sexes for the period 2013 to 2015. In Australia, 5.72 male deaths were reported for every 100,000 men, compared with 2.53 deaths per 100,000 women. Prices among men in Slovenia were 3.86 per 100,000.
Other countries, such as Slovakia and Croatia, also showed a large number of male melanoma deaths during this period.
The United Kingdom was in the middle, with 2.57 men dying per 100,000, compared with 1.58 in women. The US did not have data for this time period.
Japan saw the lowest increase in melanoma deaths over the three year period, with 0.24 men per 100,000 dying and 0.18 per 100,000 women.
The only country reporting a reduction in male melanoma deaths was the Czech Republic. There was an annual decrease of 0.7% between 1985 and 2015.
Israel and the Czech Republic were the best performing countries in reducing the female mortality rate, while Israel reported a decrease of 23.4% and the Czech Republic announced a 15.5% decrease in women's deaths due to cancer of the skin.
Exposure to ultraviolet radiation
The biggest risk factor for melanoma is overexposure to ultraviolet radiation, exposure to sunlight or the use of deck chairs, Yang explained.
Despite public health efforts to raise people's awareness of these risk factors, Yang reported that there has been an increase in melanoma incidence in recent decades, especially in areas with pure skin populations.
"We know that nine out of 10 people diagnosed with melanoma skin cancer in the UK survive their illness for at least 10 years," said Martin Ledwick, an information nurse headed by Cancer Research UK in CNN e-mail. "The growing and aging population means that more people are diagnosed with the disease than ever before."
Ledwick added that while this study shows that mortality rates for men have increased, more research is needed to find out why. "Once we know the answer, researchers can suggest men have information on how to reduce the risk of skin cancer, such as advice on maintaining their sun safety and the appearance of new spots or spots – or changes in existing – by a doctor. "
"This research shows that melanoma mortality rates are stabilizing or declining in some countries, especially for women," said Poulam Patel, president of the NCRI Skin Cancer Clinical Trials Group and Professor of Clinical Oncology at the University of Nottingham . CNN. Patel, who was not involved in the survey, added that the findings require further scrutiny.
"These results also show that melanoma will continue to be a health issue in the coming years and we need to find effective strategies for accurate diagnosis and successful treatment of patients," said Patel.
