Stomach Cancer
Gastric cancer, commonly referred to as stomach cancer, can develop in any part of the stomach and may spread throughout the stomach and to other organs; particularly the esophagus, lungs, liver and lymph nodes, a small ball or an oval-shaped organ of the immune system. Stomach cancer causes about 800,000 deaths worldwide per year. Stomach cancer is found more in men and in developing nations.

Stomach cancer
Cancer of the stomach is difficult to cure unless it is found in an early stage, before it has begun to spread. Treatment for stomach cancer may include surgery- the most common treatment, where all or part of your stomach is removed and/or other affected organs, **chemotherapy**- the use of anti- cancer drugs to stop the can cancer cells to multiply, and/or **radiation therapy**- the use of high-energy rays to kill cancer cells. Radiation therapy is usually performed with chemotherapy.
Because stomach cancer is usually diagnosed in the late stages, it is the second most common cause of cancer death worldwide, after lung cancer. In
