Stomach Cancer Risk Blood Test

What is Stomach Cancer (Gastric Cancer)?

Stomach cancer is a malignant tumor that develops in the lining of the stomach, also called gastric cancer. It is caused by chronic infection with Helicobacter pylori bacteria, which creates ongoing inflammation that can lead to cancerous changes in stomach tissue. The H. Pylori Antigen Stool test is the most important test for identifying this major risk factor and enabling early intervention.

What causes stomach cancer?

Stomach cancer is caused primarily by chronic infection with Helicobacter pylori bacteria, which infects the stomach lining and causes long-term inflammation. This persistent inflammation can lead to changes in the stomach tissue that may eventually become cancerous. Other contributing factors include smoking, a diet high in salty and smoked foods, family history of stomach cancer, and certain genetic conditions, but H. pylori infection remains the most significant preventable risk factor.

What is the best test for stomach cancer risk?

The H. Pylori Antigen Stool test is the most important test for assessing stomach cancer risk because it detects the presence of Helicobacter pylori bacteria, the leading preventable cause of gastric cancer. This non-invasive stool test identifies active H. pylori infection, which causes chronic inflammation that can progress to cancer over time. Early detection allows for antibiotic treatment to eradicate the bacteria and significantly reduce your risk of developing stomach cancer. While stomach cancer diagnosis itself requires endoscopy and biopsy, identifying and treating H. pylori infection is a crucial preventive step.

When should I get tested for stomach cancer risk?

You should get tested if you have persistent stomach pain, unexplained weight loss, frequent indigestion or heartburn, nausea or vomiting, or a family history of stomach cancer. Testing is especially important if you experience ongoing stomach discomfort that doesnt improve with over-the-counter medications, or if you have blood in your stool or black tarry stools. Early detection of H. pylori infection allows for treatment that can prevent the development of stomach cancer.

What are the symptoms of stomach cancer?
Stomach cancer symptoms include persistent abdominal pain or discomfort in the upper abdomen, feeling full after eating small amounts of food, heartburn or indigestion, nausea and vomiting, unexplained weight loss, and blood in the stool. You might also notice loss of appetite, weakness and fatigue, or swelling in the abdomen. Early-stage stomach cancer often causes no symptoms, which is why screening for risk factors like H. pylori is important for those with family history or other risk factors.
Who is at risk for stomach cancer?
People at higher risk for stomach cancer include those with chronic H. pylori infection, individuals over age 50, men more than women, and people with a family history of stomach cancer. Your risk increases if you have a diet high in smoked, salted, or pickled foods, if you smoke tobacco, if you have pernicious anemia or chronic gastritis, or if you have had stomach polyps or prior stomach surgery. Certain genetic syndromes and ethnic backgrounds, particularly Asian, Hispanic, and African American populations, also have higher stomach cancer rates.
What happens if stomach cancer risk factors are left untreated?
Untreated H. pylori infection can lead to chronic gastritis, stomach ulcers, and eventually stomach cancer over many years of persistent inflammation. The bacteria cause progressive damage to the stomach lining that can develop into precancerous changes and ultimately malignant tumors. Stomach cancer that develops and goes undetected can spread to other organs, making it much harder to treat. Early identification and treatment of H. pylori infection can prevent this progression and significantly reduce your cancer risk.
Can stomach cancer be diagnosed with a blood test?
Stomach cancer itself cannot be diagnosed with a blood test alone and requires endoscopy with tissue biopsy for definitive diagnosis. However, blood and stool tests play a crucial role in identifying major risk factors like H. pylori infection that increase your chances of developing stomach cancer. The H. Pylori Antigen Stool test detects the bacteria responsible for most stomach cancers, allowing for early intervention before cancer develops. If risk factors are identified or symptoms persist, your doctor will recommend imaging studies and endoscopy.
How is stomach cancer treated?
Stomach cancer treatment depends on the stage and location of the cancer and typically involves surgery to remove part or all of the stomach, along with nearby lymph nodes. Chemotherapy and radiation therapy are often used before surgery to shrink tumors or after surgery to kill remaining cancer cells. Targeted drug therapy and immunotherapy are newer options for advanced stomach cancer. For H. pylori infection, a combination of antibiotics and acid-reducing medications can successfully eradicate the bacteria and reduce cancer risk when caught early.
How can I prevent stomach cancer?
You can reduce stomach cancer risk by getting tested and treated for H. pylori infection, eating a diet rich in fresh fruits and vegetables, limiting smoked and heavily salted foods, and avoiding tobacco use. Regular screening is important if you have a family history of stomach cancer or other risk factors. Maintaining a healthy weight, treating stomach conditions like chronic gastritis promptly, and limiting alcohol consumption also help lower your risk. Early detection and treatment of H. pylori infection is one of the most effective preventive measures.
What can I do at home for stomach health?
You can support stomach health by eating smaller, more frequent meals, avoiding foods that trigger discomfort like spicy or acidic items, and staying hydrated throughout the day. Reducing stress through relaxation techniques, getting adequate sleep, and maintaining a healthy weight all benefit digestive health. Avoid smoking and limit alcohol, which irritate the stomach lining. While these lifestyle measures support overall stomach health, they cannot replace medical testing for H. pylori or other risk factors, so get tested if you have symptoms or risk factors.
