Stomach Cancer
Stomach cancer, also known as gastric cancer, is cancer developing from the lining of the stomach（胃黏膜）. Early symptoms（症状）may include heartburn（烧心）, upper abdominal pain, nausea（恶心） and loss of appetite. Later signs and symptoms may include weight loss, yellowing of the skin and whites of the eyes, vomiting（呕吐）, difficulty swallowing, and blood in the stool（便血）among others. The cancer may spread from the stomach to other parts of the body, particularly the liver, lungs, bones, lining of the abdomen andlymph nodes（淋巴结）.
The most common cause is infection by the bacterium Helicobacter pylori（幽门螺杆菌）, which accounts for more than 60% of cases. Certain types of H. pylori have greater risks than others. Other common causes include eating pickled vegetables and smoking. About 10% of cases run in families and between 1% and 3% of cases are due to genetic syndromes（遗传综合征）inherited from a person's parents such as hereditary diffuse（弥漫型）gastric cancer. Most cases of stomach cancers are gastric carcinomas（癌）. This type can be divided into a number of subtypes. Lymphomas（淋巴瘤）and mesenchymal tumors（间质瘤）may also develop in the stomach. Most of the time, stomach cancer develops in stages over years. Diagnosis is usually bybiopsy（活检）done during endoscopy（内窥镜）. This is followed by medical imaging to determine if the disease has spread to other parts of the body. Japan and South Korea, two countries that have high rates of the disease, screen for stomach cancer.
