Abdominal cavity tumor

Gastric cancer often has no symptoms until it has spread to other parts of the body, or the symptoms are mistaken for other conditions. This means that it can be a challenging diagnosis, especially in the early stages. However, it is important to capture and diagnose gastric cancer as quickly and accurately as possible. This helps to increase the chances of successful treatment and reduce the chance of side effects. If you are likely to have symptoms of stomach cancer, your doctor will examine you and inquire about your health status and lifestyle, including smoking and drinking habits, as well as your family medical history. One or more of the following tests can be used to determine if you have stomach cancer, if it has spread, or if the treatment is effective. Blood test: There is no blood test method that can accurately diagnose your stomach cancer. However, your doctor can conduct blood tests that provide important indicators for your health and may indicate whether other organ systems are affected by cancer. Other tests, such as whole blood cell count (CBC), can be used to check for anemia. This may be a signal that cancer cells are bleeding into the stomach. Doctors can also test your blood for cancer antigen 125 (CA-125) and carcinoembryonic antigen (CEA). These proteins, or tumor markers, are sometimes produced by cancer tumors and can be detected in the blood. These tests can be used to determine whether your cancer is growing or responding to treatment. However, not all cancers produce CEA, and high CEA levels do not necessarily mean you have stomach cancer. Fecal occult blood test: Check if there are blood stains in the feces that cannot be seen by the naked eye. This may indicate that cancer is bleeding in the stomach. Upper gastrointestinal endoscopy: A small hose with a camera at the end is inserted into the esophagus and stomach through the oral cavity. This can help your doctor look for signs of cancer. The endoscope can also be equipped with a tool to eliminate suspicious tissue samples (biopsies). Biopsy: Biopsy involves removing tissue and examining it under a microscope to determine the presence of cancer cells. Biopsy of gastric cancer is usually performed during endoscopy. Endoscopic ultrasound: The doctor inserts an endoscope equipped with a small ultrasound device into the stomach. Ultrasound uses sound waves to generate images on video screens, allowing doctors to see the depth of cancer cells infiltrating the gastric wall or to examine precancerous lesions. Imaging examination allows your doctor to see the interior of your abdomen and stomach. They can be used to confirm the location of gastric cancer and also indicate whether the cancer has spread to nearby organs. Common imaging examinations include CT or CAT (computed axial tomography) scans, positron emission tomography (PET) scans, magnetic resonance imaging (MRI) scans, and X-ray (also known as upper gastrointestinal tract) staging laparoscopy: Staging laparoscopy is a minimally invasive surgery used to determine how far the disease progresses. When the patient is under general anesthesia, the doctor will insert a thin tube containing a camera into the abdominal cavity. Then, they can carefully examine the surface of abdominal organs for signs of cancer spreading from the stomach. They can also 'flush' the abdominal cavity with physiological saline. This is called "peritoneal cleaning". The solution is removed and can be checked for the presence of cancer cells. This way, your doctor can contract cancer that is not yet visible in other imaging tests.
