More cancer cases linked to being overweight
A growing percentage of cancer cases may be attributed to high body mass index (BMI) and being overweight, according to a new study.
Scientists from the International Agency for Research on Cancer analyzed data on BMI-related cancer cases that occurred in various countries in the year 2012. The countries with the highest percentage of cancer cases that were BMI-related varied according to gender. For men, the countries with the highest incidence of BMI-related cancer were Czech Republic (in which 5.5 percent of annual new cancer cases was BMI-related), Jordan (4.5 percent) and the U.K. (4.4 percent.) For women, the top countries were Barbados (27 percent), Czech Republic (12 percent) and Puerto Rico (11.6 percent). Overall, women were found to have more new BMI-related cancer cases every year than men.
The researchers also found North America was the country with the highest number of new BMI-related cancer cases in 2012--it accounted for about 23 percent of the global cases and equaled approximately 111,000 new cases.
The findings of the new analysis, published in The Lancet Oncology, suggest that an increasing number of annual new cancer cases is expected to be linked to obesity and being overweight. A high BMI has been linked to cancers affecting the esophagus, colon, rectum, kidneys, pancreas, gall bladder, breasts, ovaries and endometrium.
