An EGD (upper endoscopy) is a procedure that allows the healthcare provider to examine the inside of the esophagus, stomach, and duodenum with an endoscope. This is guided into the mouth and throat, then into the esophagus, stomach, and duodenum.
Symptoms may include:
- Nausea.
- Vomiting.
- Fever (sometimes very high)
- Belly (abdominal) cramping and pain.
- Diarrhea, possibly bloody.
- Dehydration.
- Electrolyte imbalance.
If the results show hypochlorhydria or achlorhydria, the doctor may take blood tests to check for a deficiency in iron or other nutrients. A doctor may prescribe HCL supplements to confirm a diagnosis. If a person feels better when taking the supplements, low stomach acid is likely the cause of symptoms.
An abdominal CAT scan can detect signs of inflammation, infection, injury or disease of the liver, spleen, kidneys, bladder, stomach, intestines, pancreas, and adrenal glands.
For example, they may order computed tomography (CT) scans, magnetic resonance imaging (MRI), or endoscopy to examine your digestive tract. They may also order blood tests. To diagnose or rule out celiac disease, your doctor may order blood tests and a biopsy of your small intestine.
Ultrasonography is the initial imaging test of choice for patients presenting with right upper quadrant pain. Computed tomography (CT) is recommended for evaluating right or left lower quadrant pain. Conventional radiography has limited diagnostic value in the assessment of most patients with abdominal pain.
Doctors may identify leukemia during routine blood tests, before a patient has symptoms. If you already have symptoms and go for a medical visit, your doctor will perform a physical exam to check for swollen lymph nodes, spleen or liver.
Blood tests aren't used to diagnose lymphoma, though. If the doctor suspects that lymphoma might be causing your symptoms, he or she might recommend a biopsy of a swollen lymph node or other affected area.
Specifically, blood tests can help doctors: Evaluate how well organs—such as the kidneys, liver, thyroid, and heart—are working. Diagnose diseases and conditions such as cancer, HIV/AIDS, diabetes, anemia (uh-NEE-me-eh), and coronary heart disease. Find out whether you have risk factors for heart disease.
The most common types of blood tests used to assess heart conditions are: Cardiac enzyme tests (including troponin tests) – these help diagnose or exclude a heart attack. Full blood count (FBC) – this measures different types of blood levels and can show, for example, if there is an infection or if you have anaemia.
Abnormal red blood cell, hemoglobin, or hematocrit levels may indicate anemia, iron deficiency, or heart disease. Low white cell count may indicate an autoimmune disorder, bone marrow disorder, or cancer. High white cell count may indicate an infection or reaction to medication.
Blood testsNo blood test can definitively prove or rule out a diagnosis of rheumatoid arthritis, but several tests can show indications of the condition. Some of the main blood tests used include: erythrocyte sedimentation rate (ESR) – which can help assess levels of inflammation in the body.
A CBC blood test can help your provider diagnose a wide range of conditions, disorders, diseases and infections, including: Anemia (when there aren't enough red blood cells to carry oxygen through the body). Bone marrow disorders, such as myelodysplastic syndromes.
In addition to a physical examination, the following tests may be used to diagnose stomach cancer:
- Biopsy.
- Molecular testing of the tumor.
- Endoscopy.
- Endoscopic ultrasound.
- X-ray.
- Barium swallow.
- Computed tomography (CT or CAT) scan.
- Magnetic resonance imaging (MRI).
Signs of Cancer
- Change in bowel or bladder habits.
- A sore that does not heal.
- Unusual bleeding or discharge.
- Thickening or lump in the breast or elsewhere.
- Indigestion or difficulty in swallowing.
- Obvious change in a wart or mole.
- Nagging cough or hoarseness.
Testing For Stomach Cancer
- Upper endoscopy.
- Endoscopic ultrasound.
- Biopsy.
- Upper gastrointestinal (GI) series.
- Computed tomography (CT or CAT) scan.
- Magnetic resonance imaging (MRI) scan.
- Positron emission tomography (PET) scan.
- Chest X-ray.
As the cancer progresses, the symptoms that do appear can be misdiagnosed as normal gastrointestinal issues. As a result, stomach cancer can go undetected for years before the symptoms become concerning enough to warrant diagnostic testing.
The most common place for stomach cancer to spread is to the liver. It can also spread to the lungs, to lymph nodes or to the tissue lining the abdominal cavity (peritoneum).
The study findings suggest that higher WBC levels are a risk factor for gastric cancer, especially in subjects with H. pylori infection.
Imaging tests usually can't tell if a change has been caused by cancer. CT scans can produce false negatives and false positives. CT scan can miss cancer, or miss tumors in other areas of the body. CT scans are proven to be less effective at diagnosing cancer than PET/CT.
Stomach cancer is a slow-growing cancer that usually develops over a year or longer. Generally, there are no symptoms in the early stages (asymptomatic). As the disease progresses, a variety of symptoms can develop.
If the tumor starts in the small intestine, it can cause the intestines to kink and be blocked for a while. This can cause cramps, belly pain, weight loss, fatigue, bloating, diarrhea, or nausea and vomiting, which might come and go.
Sometimes there are no signs or symptoms of stomach cancer or duodenal or gastric ulcers, and when they do occur, they may include nausea and loss of appetite with no clear cause. Other similar signs and symptoms of stomach cancer and stomach ulcers include weight loss and anemia.
Gas and bloating: Excessive gas and bloating can be a sign of colon cancer. However, dietary triggers (for example, carbonated beverages, dairy products, and high-fiber foods) and digestive disorders (for example, inflammatory bowel disease) are common culprits.
Most patients with early-stage stomach cancer have no symptoms of the disease. In other cases, stomach cancer patients may mistake their symptoms for a common stomach virus. When the signs and symptoms of stomach cancer are not apparent, the disease may reach advanced stages before a diagnosis is made.
Gastric cancer is often in an advanced stage when it is diagnosed. At later stages, gastric cancer can be treated but rarely can be cured. Taking part in one of the clinical trials being done to improve treatment should be considered.
Unfortunately, stomach cancer often shows no outward signs or symptoms in the early stages. However, if you experience any of the following, you should talk with your doctor: Indigestion or a burning sensation (heartburn)Discomfort or pain in the abdomen.
