About Stomach Cancer

What is Stomach Cancer?

Stomach cancer, also known as gastric cancer, is cancer of the stomach.  It begins there, and like other types of cancer, can spread to other parts of the body.  Because the stomach shares the abdomen with other organs, it is extremely important to be able to recognize the source of other pains and symptoms.  Organs such as the colon, pancreas, and liver, among others, are also in this part of the body, and those types of cancers do not always share the same symptoms and treatments, as well as the same outlook.

By the numbers

In 2018, there will be an estimated 1 million new gastric cancer cases and nearly fifteen million new total cancer cases worldwide.  In the United States alone, there will an estimated 28,000 and 1.7 million new cases respectively.  Gastric cancer is the fifth most common type of cancer in the world, and the five year survival rate for the disease is 28%.  The survival rate drops dramatically from Stage IA to Stage IIA and later stages.

Road map of the stomach

When traveling through the body, and the stomach more specifically, the first part that is reached is the Cardia, followed bu the upper part of the stomach called the Fundus, and then the body of the stomach also known as the Corpus.  When continuing through, the lower portion is called the Antrum which is near the intestines, and lastly, the last part of the stomach is called the Pylorus.
