Stomach cancer is caused by a genetic mutation in the stomach’s cells. Your DNA determines when cells grow and die, and cancerous cells will overgrow and invade healthy cells. It’s also more common in people with Type A blood. A doctor can perform a biopsy to determine whether the cancer is spread throughout your body or just to the stomach. If it has spread to other organs, it can spread to the lymph nodes.
The first step in diagnosing stomach cancer is to visit a doctor who will order a physical exam and take a detailed account of your symptoms. Your doctor will then order tests to determine the cause of your symptoms and refer you to a gastroenterologist who can perform specialized tests. Some tests to look for stomach cancer include upper endoscopy and endoscopic ultrasound (EGD). These tests will reveal if you have cancer or if it has spread to lymph nodes nearby.
Treatment for stomach cancer will depend on its stage. The stage can vary significantly from patient to patient, but most treatments have the same basic components. For example, subtotal gastrectomy involves removal of a portion of the stomach with cancer. In some cases, the entire stomach, including nearby lymph nodes, may be removed. In addition to surgical removal, patients may also undergo a procedure called gastrojejunostomy to connect the stomach to the small intestine. After the surgery, the patient will receive food through a tube into the small intestine. Endoluminal stents may be used to help keep the passage open.
Some stomach cancer symptoms may be caused by other conditions. You should seek medical treatment for any symptoms before undergoing surgery. If your doctor suspects stomach cancer, you should see your primary care physician. If you have a suspicion that your symptoms may be a symptom of another illness, your doctor may refer you to a gastrointestinal cancer specialist who can confirm the diagnosis and determine the stage of the disease. If the disease has spread to other organs, treatment will depend on the stage of the disease.
Certain cooking methods may be associated with increased risk of stomach cancer. People who work in industries with high levels of dust are at higher risk. Other causes include those who work in the rubber industry or in factories that produce diesel exhaust. A diet that is low in fruits and vegetables may be a risk factor. While some of these factors are preventable, others are entirely unknown. If you don’t avoid eating enough fruits and vegetables, you may reduce your risk of developing stomach cancer.
Early signs of stomach cancer can be difficult to detect. Many stomach cancer symptoms resemble symptoms of other illnesses. You may have unexplained weight loss, constipation, indigestion, or heartburn. You may also experience vomiting of blood or black stools. You may experience indigestion or heartburn, as well as feel bloated after eating. You may also notice unexplained fatigue or weakness. In addition, your doctor may order tests that reveal the presence of cancer cells.
