Cancer stomach

Cancer of the stomach is a type of cancer that starts in the cells of the stomach. It is also known as gastric cancer. It is a serious disease that can be life-threatening if not treated. The stomach is a hollow organ in the upper abdomen, which is responsible for churning and breaking down food, and then transferring it to the small intestine for absorption. Cancer of the stomach occurs when the normal cells in the stomach grow abnormally and out of control, forming a mass called a tumor. These tumors can be benign, which means they are non-cancerous, or malignant, which means they are cancerous. The exact cause of stomach cancer is unknown, but there are several risk factors that can increase the chances of developing it, such as a family history of the disease, having an inflamed or infected stomach lining (gastritis or ulcer), or smoking. Stomach cancer is usually diagnosed with an endoscopy, which is an examination of the inner lining of the stomach using a small camera and light. Other tests may include a biopsy and imaging tests such as a CT scan or MRI. Treatment for stomach cancer depends on the size, location, and stage of the cancer, but may include surgery, chemotherapy, and/or radiation therapy.
