While it is very difficult to find out whether you have gastric cancer until it has spread to other parts of the body, you can find out if you are at risk by checking your symptoms. You may want to get a second opinion from your doctor if you feel something is off. Many doctors welcome second opinions, and many health insurance companies pay for them. However, some cases require you to go to a specialist immediately.

There are several factors that increase the risk of gastric cancer. Several factors, such as certain genetic mutations, environmental conditions, and infections, can increase the risk. Symptoms of gastric cancer may vary from person to person. Your doctor may suggest screening for certain factors to reduce your risk. However, remember to keep in mind that you are at risk for stomach cancer even if you are not at high risk. You must also keep in mind the warning signs of gastric cancer and take precautions to avoid them.

Early detection is crucial for successful treatment. Gastric cancer can spread to nearby lymph nodes or organs. In addition to cancer in the stomach, it can also spread to the tissues lining the wall of the abdomen. Once diagnosed, it can recur if treatment is unsuccessful. However, if diagnosed in time, it is possible to undergo a surgery and have a cure. You may also want to take part in a clinical trial. Clinical trials involve testing new treatments to determine which one will work best for your particular case.

Surgical treatment is the most common treatment for gastric cancer. A surgeon removes part of the stomach, along with the lymph nodes and nearby tissues that surround the tumor. In some cases, the surgeon may also remove parts of the spleen, which produces lymphocytes and red blood cells. This organ is located on the left side of the abdomen. A second treatment option is an endoscopic mucosal resection (EMR), which is pioneered in Japan. Several centers in the United States are equipped to perform this procedure.

Medical examination may reveal the presence of blood and swollen lymph nodes. The doctor may also order a biopsy. This procedure involves the removal of a small portion of tissue from the stomach and studying it under a microscope. In addition to a biopsy, your doctor may perform endoscopic ultrasonography and specially computed tomography. These procedures use x-rays and a computer to produce cross-sectional images of tissue. During a CT scan, your doctor may also examine your chest and abdomen to determine if your stomach cancer has spread.

Some cancers are familial. Unlike colon cancer, stomach cancer has no known genetic cause. However, certain lifestyle choices are associated with a higher risk. Certain diseases, such as smoking, can increase the inflammation in the stomach. Furthermore, individuals who are suffering from chronic illness are more susceptible to developing gastric cancer than those who are healthy. Other common symptoms include stomach ulcers, H. pylori bacterial infections, and stomach polyps, an abnormal growth of tissue in the lining of the stomach.

Early stage stomach cancer may not have any symptoms. But in later stages, symptoms of gastric cancer may include severe dyspepsia, abdominal discomfort, and unintended weight loss. Some people also experience severe persistent heartburn. In addition to these symptoms, gastric cancer patients may experience bowel obstruction and swelling in the abdomen. If you experience any of these symptoms, contact your doctor right away. By early detection, you may prevent complications from developing.

A doctor will usually perform imaging tests to check for signs of gastric cancer. Imaging tests may include computed tomography (CT) scans or endoscopic ultrasounds. Barium swallow imaging is a procedure in which a small light tube is passed through the mouth to observe the digestive tract as liquid moves down it. X-rays of the upper digestive tract are also performed to examine the organs for any signs of cancer.

A gastroscopy examination allows doctors to see suspicious features and take a biopsy for histological confirmation. This examination typically takes 10 minutes and is performed as an outpatient procedure. The usual screening investigation for gastric lesions is a barium meal X-ray. Additional investigations include MRI, CT scans, and PET scans. Some patients may have a total gastrectomy before diagnosis. A symptom-free survival rate of about 30 percent is the ideal outlook for this disease.
