Gastric Cancer
Stomach cancer, or gastric cancer, is the abnormal growth of cells in the stomach, a key organ in digestion located just below the ribs. It can occur in any stomach region, though globally it's most common in the main body of the stomach, in some cases it may also start near the gastroesophageal junction. Treatment depends on tumor location, stage, and cell type, and may involve surgery, chemotherapy, radiation, or targeted therapy. Early detection offers the best chance for a cure, but most cases are diagnosed at advanced stages, making treatment more difficult.
Who Is Affected by Stomach Cancer
Stomach cancer can affect individuals of any age, but certain demographic groups are at higher risk:
- People aged 65 and older.
- Men, who are more frequently diagnosed than women.
- Those of South American, Central American, Eastern European, or East Asian descent.
Gastric Cancer Risk Factors
A wide range of biological, lifestyle, and environmental factors contribute to the development of head and neck cancers:
Medical and Genetic Risk Factors:
- H. pylori infection, a common stomach infection that can lead to ulcers.
- Tumors in other parts of the digestive system.
- Stomach polyps, which are abnormal growths on the stomach lining.
- Inherited genetic syndromes, such as Lynch syndrome and Li-Fraumeni syndrome.
Demographic and Lifestyle Risk Factors:
- Older age (especially 60s and above).
- Smoking and tobacco use.
- Being overweight or obese.
- A family history of stomach cancer.
- Consumption of a diet high in salty, processed foods, and red meat.
- Low intake of fruits and vegetables.
- Heavy alcohol consumption (three or more drinks per day).
- Physical inactivity.
- Poor food storage or unsafe cooking practices.
Symptoms of Gastric Cancer
In its early stages, stomach cancer rarely causes noticeable symptoms. When symptoms do occur, they are often vague and can resemble other digestive issues. Common signs include:
- Unexplained weight loss.
- Stomach pain, especially above the belly button.
- Loss of appetite.
- Nausea or vomiting, sometimes with blood.
- Heartburn, indigestion, or a bloated feeling after eating.
- Black, tarry stools.
- Trouble swallowing.
- Fatigue or general weakness.
- A sensation of fullness after eating small amounts.
Because many of these symptoms are shared with other gastrointestinal conditions, medical evaluation is important for accurate diagnosis.
