Gastric cancer and gastric cancer, refers to cancer arising from any part of the stomach. The gastric cancer, about 80 million people and cause of death in the year all over the world. Most patients, the prognosis, such as exhibiting a high degree of disease, poor (15% from <5 5-year survival rate). Or is (produced without noticeable symptoms) or often asymptomatic, as well as symptoms is not a gastric cancer only (specific symptoms of non-specific only, stomach cancer, disease or irrelevant, other related in the first stage for) there is a possibility. By the time symptoms appear, cancer is the main cause (of the body, spreading remote, in part possibly other) has reached the stage to advanced also often (see below), and may transition relatively poor prognosis. The stomach cancer, may lead to signs and symptoms of the following.

The most gastric cancer by Helicobacter pylori infection. This is why proven, but some foods such as pickles smoked food like this, and meat, and salted fish, nutritional factors that are associated with high risk. Nitrite and nitrate can be a compound which can cause stomach cancer in animals has been discovered, by certain bacteria, including H. pylori, is turned on in sausage. On the other hand, and, it is recommended to eat fresh fruits and vegetables that contain antioxidant vitamins, such as A and B to the American Cancer Society, they Mediterranean diet and, say, reduce the risk of cancer of the stomach, stomach and is associated with lower levels of cancer. Smoking increases the risk of developing gastric cancer significantly by in order to increase 82% for heavy smokers, risk 40% of current smokers is increased. In some studies, the esophagus has shown an increased risk of alcohol as well, gastric cancer caused by smoking occurs in the upper portion of the stomach mostly.

Other factors that are associated with increased risk is the genetic factors (hyperplasia, stomach hypersecretion), intestinal metaplasia, and autoimmune atrophic gastritis, pernicious anemia, Alzheimer Menetrier minutes. H. pylori is the main risk factor of 80% from 65 of cancer of the stomach, but only 2% of such infections. Pylori-induced mechanism of stomach by H. involves the virulence factors of action pylori or chronic inflammation of the H. CagA potentially. About 10% of patients showed a genetic component. Causal relationship has not been established, but several studies have correlated shows the spores of the consumption bracken, the incidence of cancer of the stomach. Gastric cancer, shows the male-dominated its incidence up to three men that are affected for all women. Estrogen, you may want to protect women from the development of this cancer form. A small percentage is believed to be a gene (forward references histopathology) very diffuse type gastric cancer. Hereditary diffuse gastric cancer, have been identified (HDGC) recently, research is in progress. However, treatment options and genetic testing is available for families at risk now. The International Cancer Genome Consortium effort to complete the genome map of gastric cancer.

Gastric adenocarcinoma is a malignant epithelial tumor arising from glandular epithelium of the gastric mucosa. Mainly adenocarcinoma stomach cancer is a (90%). Diffuse or intestinal Type: Histologically, there is a (Lauren classification) main types of gastric adenocarcinoma 2. Adenocarcinoma, for muscularis mucosa, the submucosa, there is a tendency to invade the gastric wall penetration of specific muscle layer actively. Tumor cells in the intestinal adenocarcinoma describes holding lumen pluristratification, multiple, irregular tubular structure, the stroma was reduced (the side of the “parallel”). In many cases, it is associated with intestinal metaplasia in the mucosa adjacent. Depending on the mucosecretion and polymorphic gland architecture, cell, be presented three times of differentiation can be adenocarcinoma: well, moderate and poorly differentiated. Is mucus (mucus, colloid, linitis plastic, leather bottle stomach) tumor cells come in the production of a large group and stromal discohesive, of (space of “empty” optically) mucus / colloid diffuse type adenocarcinoma. It is well distinguished. The fluid, if left in the tumor cells, which pushes the core towards “signet ring cell”, the outer periphery.

Cancer cells, is that when it is detected in a tissue sample, the next step is performed, or to grasp the extent of the disease. In various tests, it is determined cancer whether the spread, and if so, which parts of the body are affected. Gastric cancer is possible to order the tests or other tests, CT scans, PET, of the ultrasound endoscope in order to be able to spread to other organs liver, pancreas and near the stomach, doctor lung checks These areas. For example, blood tests for tumor markers carbohydrate antigen carcinoembryonic antigen and (CEA), such as (CA) may, extent of metastasis in the liver, and is disposed as a level of correlation and their cure rate in particular. Staging may not be complete until after surgery. Nearby lymph nodes, the surgeon removes the tissue samples possibly from other parts of the abdomen for examination by a pathologist.
