Deadly cancers in men are significantly more common
Men succumb to the consequences of cancer more than women. This is the conclusion reached by epidemiologist Michael Cook from the US National Cancer Institute as part of the evaluation of the cancer registry SEER.
The US researcher evaluated cancer registry data on 36 different cancers, finding that men die more often from cancer than women. When presenting the study in the current issue of "Cancer Epidemiology, Biomarkers & Prevention", Michael Cool explained that men "carry a greater risk of death than women in a majority of cancers." One reason for this could be the more regular visits to the doctor by women the scientist suspects. Because in men, the tumors are often at an advanced stage at the time of diagnosis.
Clear gender-specific differences in cancer deaths Together with his colleagues from the US Cancer Institute, Cook analyzed the data from the cancer registry SEER for 36 different types of cancer. The researchers were able to determine clear differences between the disease courses of women and men. Men with cancer succumbed to the consequences of their cancer more often than women, the US scientists report. The gender-specific differences were particularly clear in the case of fatal carcinomas in the oral cavity and on the larynx (Cook and colleagues). According to the latest study, around five times more men than women die from the consequences of these two forms of cancer. In addition, the ratio of male and female cancer victims was 5.51 to one in lip cancer, 4.08 to one in esophageal cancer (esophageal carcinoma) and 3.36 to one in cancer of the bladder, the US researchers said. Overall, the chances of survival for women in the aforementioned cancers were therefore significantly better than those for men.
Cancers with the highest mortality rates The gender-specific differences have also been confirmed for cancer with the highest mortality rates, Cook and colleagues write. Men die 2.31 times more often from cancer of the lungs or bronchi, 1.42 times more often from colorectal cancer (colorectal cancer) and 1.37 times more often from pancreatic cancer (pancreatic cancer). With so-called blood cancer (leukemia), there are 1.75 times more male fatalities than women. In cancer of the liver and bile ducts, the ratio was 2.23 to one. A clear exception is breast cancer, for example, in which significantly more women suffer than men. So far, the US researchers have not been able to clearly clarify what causes the gender-specific differences in fatal cancer.
Reduced risk of cancer through more regular visits to the doctor? Epidemiologist Michael Cook said that some of his colleagues believed that this could be due to the more frequent visits to the doctor and the increased participation of women in cancer screening and screening tests. However, according to the expert, the 5-year survival rates for the various types of cancer speak against this assumption. Because here only slight gender-specific differences can be determined. Michael Cook assumes that the clear differences in fatal cancer are more likely to be attributed to the causes of the disease than to the more regular visits to the doctor. (fp)
