National Stomach Cancer Awareness Month



November is National Stomach Cancer Awareness Month. In the United States stomach cancer is the seventh most common cause of death from cancer. There are several different types of stomach cancer, including gastric adenocarcinoma, lymphomas, and leiomyosarcomas. The most common type of stomach cancer accounting for about 95 percent of all stomach cancer cases is gastric adenocarcinoma. Gastric adenocarcinoma is when cancer cells develop from the gland cells in the innermost lining of the stomach. It is important to know the symptoms, causes, risk factors, and treatment of stomach cancer to ensure if one develops stomach cancer early detection is possible. The month of November is dedicated to raising awareness to educate people about stomach cancer.
