Gastric Cancer


Gastric cancer, which ranks the 4th place in most common cancer types, is located in any part of the stomach and can usually spread to other organs such as lymph glands, liver and lungs. Gastric cancer is caused by the development of malignant tumors in gastric mucosa due to various reasons. Gastric cancer has many reasons. Gastric cancer may develop in any part of the digestive system organs and spread to other organs. Behaviors and risk factors affecting all organs in the digestive period may trigger gastric cancer. These can be listed as follows:

Nutrition Habits

The most important reason for gastric cancer is inappropriate nutrition habits. In particular, meat and similar foods baked on the barbecue, excessively salted and brined vegetables, processed foods lead to gastric cancer.



Another important factor causing gastric cancer is H-pylori infection. In 65-85% of gastric cancer cases, H. pylori infection is seen. In 2% of the patients with H. pylori infection, gastric cancer is found.


Smoking and Alcohol

Smoking is another reason for gastric cancer which can be prevented. When consumed together with alcohol, in particular, it increases the risk of gastric cancer. The risk of gastric cancer can be reduced by avoiding smoking and alcohol.



As in all other cancer types, genetic factors are important in gastric cancer. At about 10% of gastric cancer cases, genetic factors are prominent.

After determining the type of cancer with the diagnosis of gastric cancer, the treatment method is decided. Success is achieved with experienced team work and fully-equipped hospital. It is the most important part of treatment to remove the tumor causing cancer in an appropriate way in gastric cancer treatment. Successful surgical operations made at the early period are very important for the patient’s survival period and life comfort. The surgical method to be applied is planned to depend on the location of cancer and whether it has a regional or distant extension. An upper-umbilicus midline incision is more appropriate for the operation to be applied for gastric cancer. In case of tumors located in the lower part of the esophagus and at the entrance of the stomach, it may sometimes be necessary to open the chest cage. The surgical method to be applied is gastrectomy (removal of stomach). There are two types of gastric cancer surgery: cancerous part of the stomach is removed in partial gastrectomy. The surgeon may also remove a part of the esophagus and small intestine. Close lymph glands and other tissues can be removed as well. Tumors are most commonly seen in the last third part of the stomach. In this case, it is sufficient to remove the last part of the stomach. In total gastrectomy; the whole stomach, surrounding lymph glands, esophagus and parts of the small intestine and other adjacent tissues to the tumor are removed. Then, the surgeon bends the esophagus directly to the small intestine. The surgeon makes a new stomach from the intestine. Removal of the spleen can also be added to this operation. It is more appropriate to remove the whole stomach for the tumors located in the middle or upper one-third part. The recovery period after operation varies for each person.
