Stomach cancer deaths per million persons in 2012 Worldwide, stomach cancer is the fifth most-common cancer with 952,000<unk>  diagnosed in 2012. It is more common both in men and in developing countries. In 2012, it represented 8.5% of cancer<unk>  in men, making it the fourth-most common cancer in men. Also in 2012, the number of deaths was 700,000, having decreased slightly from 774,000 in 1990, making it the third-leading<unk> of cancer-related death (after lung cancer and liver cancer). Less than 5% of stomach cancers occur in people under 40 years of age, with 81.1% of that 5% in the age-group of 30 to 39 and 18.9% in the age-group of 20 to 29. In 2014, stomach cancer resulted in 0.61% of deaths (13,303<unk>  in the U.S. In China, stomach cancer accounted for 3.56% of all deaths (324,439<unk> . The highest rate of stomach cancer was in Mongolia, at 28<unk>  per 100,000 people. In the United Kingdom, stomach cancer is the 15th-most common cancer (around 7,100 people were diagnosed with stomach cancer in 2011), and it is the 10th-most common<unk> of cancer-related deaths (around 4,800 people died in 2012). Incidence and mortality rates of gastric cancer vary greatly in Africa. The GLOBOCAN system is currently the most widely used method to compare these rates between countries, but African incidence and mortality rates are seen to differ among countries, possibly due to the lack of universal access to a registry system for all countries. Variation as drastic as estimated rates from 0.3/100000 in Botswana to 20.3/100000 in Mali have been observed. In Uganda, the incidence of gastric cancer has increased from the 1960s measurement of 0.8/100000 to 5.6/100000. Gastric cancer, though present, is relatively low when compared to countries with high incidence like Japan and China. One suspected<unk> of the variation within Africa and between other countries is due to different strains of the H. pylori bacteria. The trend commonly seen is that H. pylori infection increases the risk for gastric cancer, but this is not the case in Africa, giving this phenomenon the name the "African enigma". Although this bacterial species is found in Africa, evidence has supported that different strains with mutations in the bacterial genotype may contribute to the difference in cancer development between African countries and others outside the continent. Increasing access to health care and treatment measures have been commonly associated with the rising incidence, though, particularly in Uganda.
