Stomach Cancer

The exact causes of cancer of the stomach are still unknown. Over the past years the number of people with the disease has fallen considerably, especially in Western countries. Although the reason for this is unknown it is thought to be related to changes in our diet particularly the use of refrigeration which means people can now eat more fresh food and less smoked and pickled food. Cancer of the stomach is more common in men, particularly in late middle age. It is also more common in people who have a condition known as pernicious anaemia, which affects the lining of the stomach and results in a lack of vitamin B12. There is no proven link between stomach ulcers and the development of cancer of the stomach.
