Stomach Cancer Research Paper

Cancer is a dangerous disease that is caused by an uncontrolled group of abnormal cells in the body. Cancerous cells, also known as malignant tumors or neoplasm, begin to divide without stopping and invade surrounding tissues. The body is made up of trillions of cells, which means cancer can start from almost anywhere in the body. Human cells grow and divide to form new cells continuously. When cells grow old or become damaged they die and new cells are formed to take their place. This process is not the same when cancer starts to develop. As cells become more and more abnormal, old, or damaged instead of dying, they survive and these mutated cells no longer exhibit their original behavior. These new cells have the ability to divide without
The stomach produces many digestive juices and acids that mix with food and help in the process of digestion. Cancer in the stomach just like any other type of cancer is not something pleasant. Stomach cancer is a disease in which the stomach cells become cancerous and grow out of control, creating a tumor. Almost all stomach cancers start in a tissue that lines the stomach called the glandular. The tumors these cells create have the ability to spread along or grow directly through the stomach wall, and shed cells into the blood stream or lymphatic system. Once these cancerous cells break through the stomach they then can move on and spread the cancer to other parts of the body and to different organs, this spread is referred to as metastasis. There are five regions of the stomach cardia, fundus, antrum, pyloric and the pylorus. Doctors refer to these regions when determining where a stomach cancer begins. Cancer can develop in any of these five sections of the stomach, depending on the location of the cancer, the symptoms and outcomes of the disease will vary. There are also four stages of cancer for doctors and patients to know how far along and how severe their cancer actually
Normally these cells and tissues help protect our bodies against infection. Lymphoma cells and tissues affected maybe located in the lymph nodes or in lymphoid tissues located in other sites of the body such as the central nervous system, gastrointestinal tract and the skin. The lymphomas affecting the gastrointestinal tract, the stomach is the most commonly affected site, then the small and large intestines. Symptoms of lymphoma cancer include upper abdominal pain, upset stomach or indigestion, change of bowel habits, nausea and vomiting, loss of appetite, and weight loss. Most cases of gastric lymphoma occur in those who are fifty or above. Males are at a two to three times greater risk for developing gastric
