Stomach cancer, also known as gastric cancer, affects the stomach lining and is one of the most common cancers worldwide. This type of cancer is often diagnosed in later stages due to its subtle early symptoms. This post will cover essential information about stomach cancer, including symptoms, risk factors, detection methods, and prevention tips.
What is Stomach Cancer?
Stomach cancer begins in the cells of the stomach lining and often grows slowly over many years. The most common type is adenocarcinoma, which starts in the cells lining the stomach’s inner layer. Other, rarer types include lymphomas, gastrointestinal stromal tumors (GISTs), and carcinoid tumors. Due to the vague nature of early symptoms, stomach cancer is often diagnosed at a later stage, highlighting the importance of understanding symptoms and risk factors.

Symptoms of Stomach Cancer
Stomach cancer symptoms can be subtle and often mimic other gastrointestinal issues. Common symptoms include:
- Persistent Indigestion or Heartburn: Chronic indigestion or burning sensation in the stomach.
- Feeling Bloated After Eating: A sensation of fullness after eating small amounts of food.
- Loss of Appetite and Unexplained Weight Loss: A significant decrease in appetite and unintended weight loss.
- Nausea and Vomiting: Frequent nausea or vomiting, especially if there’s blood in the vomit.
- Stomach Pain or Discomfort: Abdominal pain or discomfort, often in the upper part of the stomach.
If you experience these symptoms persistently, especially along with unexplained weight loss, it’s essential to seek medical advice.
How to Detect Stomach Cancer
Detecting stomach cancer early can lead to more effective treatment. Here are common methods for detection:
- Endoscopy: During an endoscopy, a thin, flexible tube with a camera is used to examine the stomach. A biopsy may be taken if abnormal tissue is detected.
- Biopsy: A sample of stomach tissue can be taken during an endoscopy to examine it for cancer cells.
- Imaging Tests: CT and PET scans provide detailed images of the stomach and can detect tumors or spread of cancer to other organs.
- Upper GI Series: Also called a barium swallow, this X-ray imaging test involves drinking a barium solution to help highlight abnormalities in the stomach.
Risk Factors for Stomach Cancer
Several factors increase the risk of developing stomach cancer:
- Infection with H. Pylori Bacteria: This bacterial infection is a major risk factor, causing chronic inflammation and potentially leading to cancer.
- Diet: A diet high in smoked, pickled, or salted foods is linked to increased risk. Low intake of fruits and vegetables also contributes.
- Smoking: Smokers have a higher risk of stomach cancer, especially in the upper part of the stomach.
- Family History: A family history of stomach cancer can increase risk.
- Chronic Gastritis or Anemia: Long-term inflammation or conditions like pernicious anemia can increase risk.
- Obesity: Excess body weight, particularly around the abdomen, is associated with higher stomach cancer risk.
Prevention Tips for Stomach Cancer
While not all cases of stomach cancer can be prevented, certain lifestyle adjustments may help reduce risk:
- Treat H. Pylori Infections: Screening and treatment of H. pylori infections can help reduce stomach cancer risk.
- Limit Smoking and Alcohol: Avoiding smoking and limiting alcohol intake are essential steps in reducing cancer risk.
- Balanced Diet: Eating a diet rich in fruits, vegetables, and whole grains provides protective nutrients. Limiting smoked, salted, or pickled foods is also beneficial.
- Healthy Weight: Maintaining a healthy weight and engaging in regular physical activity can help lower cancer risk.
Conclusion
Stomach cancer is a serious disease often diagnosed in later stages, as early symptoms can be subtle and similar to common digestive issues. Recognizing the symptoms, understanding risk factors, and taking preventive steps can help improve outcomes. If you experience persistent digestive discomfort, unexplained weight loss, or other concerning symptoms, consult a healthcare provider.
Prioritize your health with regular check-ups and a balanced lifestyle—early detection and proactive management can make a significant difference.
