Men in Northern Ireland are 40% more likely than women to die of cancer, according to the latest statistics.
Cancer death rates among men in NI are 40% higher
Figures released by the Northern Ireland Cancer Registry on Thursday show a marked difference in cancer death rates between men and women.
However, the number of women dying from the disease is increasing.
BBC NI's health correspondent Dot Kirby said the difference between men and women was reflected across the developed world.
"The standardised figures show a stark difference, " she said.
"For every 100,000 women, 160 will die of cancer. But for every 100,000 men, 224 will die from cancer.
"It is thought this is because, historically, men have indulged in behaviour that increased their risk," she said.
Professor Liam Murray from the NI Cancer Registry said: "We don't feel that the explanation for this difference between men and women is that women are protected against cancer in any way.
"It is more likely that men do things that increase their cancer risk or don't do things that would reduce their risk."
Professor Murray said these could be simple things such as lifestyle. He said the difference was quite marked for smoking or alcohol related cancers.
Researchers predict that current smoking and drinking patterns mean cancer rates among women are expected to rise.
