The first step in determining whether or not you have gastric cancer is to get a biopsy. A biopsy involves taking tissue and cells from your stomach. The procedure is often performed during an endoscopy. It can be used to diagnose the condition by measuring HER2 gene expression or protein content. If the cancer is HER2-positive, treatment will most likely involve a monoclonal antibody. In addition, a biopsy can check for Helicobacter pylori infection, which can affect the prognosis.

Early stage cancers of the stomach do not cause any symptoms, but as the tumor grows, patients start experiencing difficulty swallowing. Because the esophagus is narrowed by the tumor, swallowing can be difficult. Symptoms include indigestion, heartburn, choking, and vomiting. Involuntary weight loss is another warning sign of gastric cancer. Some cancers may also spread to the lymph nodes, pancreas, liver, and colon.

As the cancer grows and spreads, it may reach deeper layers of the stomach. By the time the cancer reaches stage 4, it may have spread to nearby lymph nodes or distant organs. Treatment can include radiation therapy and chemotherapy. It can also involve surgery to remove part of the stomach. The surgeon may remove lymph nodes. If the cancer is still localized to the stomach, the doctor may recommend radiation therapy or chemotherapy to shrink the tumor. The radiation therapy will help the body fight the cancer.

The earliest signs of the disease are nonspecific and not indicative of the disease. The symptoms of gastric cancer are primarily caused by a variety of risk factors, including age. For instance, people over age 50 and smokers are twice as likely to develop the disease than white people. There is also an increased risk of developing gastric cancer if someone has a family history of stomach cancer. In addition to cigarette smoking, high salt intake and Helicobacter pylori infection are known risk factors.

If your symptoms are consistent with gastric cancer, you should visit a gastroenterologist immediately. In addition to gastroenterologists, surgeons, and medical oncologists, gastric cancer specialists include radiation oncologists, medical oncologists, and surgeons. A registered dietitian and an oncology nurse may also be part of your team. However, your doctor may recommend a more advanced form of treatment.

Fortunately, stomach cancer is highly preventable. A healthy diet is crucial in preventing the disease and detecting the symptoms. Eat plenty of fresh fruits and vegetables to help reduce your risk of developing the disease. Additionally, reducing the risk factors can significantly increase your chances of survival. You can also perform simple tests to raise suspicion. Simple blood tests can also detect anaemia and occult blood in the stool. While the symptoms of gastric cancer are generally non-specific, it is important to see a doctor to rule out any serious illnesses.

The first sign of gastric cancer is often non-specific. It may be associated with an ulcer, resulting in bleeding and vomiting. In addition, gastric cancer can also cause slow, chronic loss of blood. This may lead to anaemia. Advanced cancer may also cause obstruction to the stomach, leading to early satiety and vomiting. The best way to detect gastric cancer is to undergo a colonoscopy or upper GI endoscopy.

In addition to a physical examination, gastric cancer can spread to nearby organs and lymph nodes. It may also spread to the tissue that lines the abdomen wall. Symptoms of gastric cancer often recur after treatment. Fortunately, treatment options for this disease continue to improve, and new treatments are being tested in clinical trials. However, if you notice any of the symptoms listed above, it is important to get checked immediately.

The median age at which a person is diagnosed with gastric cancer is 68 years old. However, younger people are at increased risk for the condition, and there are fewer cases of gastric cancer in individuals younger than 35. Younger people may also have a genetic predisposition to the disease. If you have a family history of gastric cancer, it is important to visit a doctor as soon as possible.

Although the majority of participants in these studies experienced multiple symptoms before receiving a diagnosis, one of the most common was dysphagia. About half of the participants also reported fatigue. While dysphagia may indicate a more serious underlying problem, dysphagia is one of the most common signs of gastric cancer. The other two most common symptoms were tiredness and dysphagia. The research team concluded that gastric cancer sufferers are likely to experience several different types of symptoms, such as a variety of other symptoms.
