Gastric (stomach) Cancer Doctor in Indore

Gastric (stomach) cancer refers to malignancies that arise from the cells lining the stomach. Most cases are adenocarcinomas, but there are other less common types. Early-stage stomach cancer is often asymptomatic, making early detection a challenge.

Common Types of Gastric Cancer

• Adenocarcinoma: More than 90% of gastric cancers, originating from the glandular tissue of the stomach lining.

• Lymphoma: Cancer of the immune system tissue found in the stomach, accounting for up to 4% of cases.

• Gastrointestinal stromal tumor (GIST): Arises from connective tissue in the stomach.

• Neuroendocrine (carcinoid) tumors: Originate from hormone-producing cells.

Symptoms

• Indigestion or heartburn (dyspepsia).

• Abdominal pain or vague discomfort above the navel.

• Feeling bloated or full after eating small amounts.

• Nausea and vomiting (sometimes with blood).

• Loss of appetite and unintentional weight loss.

• Tiredness, weakness, or anemia.

• Black or blood-stained stools.

• Trouble swallowing and swelling of the abdomen.

Symptoms often appear late and can mimic other digestive conditions.

Risk Factors

• Age over 60; most commonly diagnosed in older adults.

• Male sex (men have a higher risk than women).

• Infection with Helicobacter pylori (H. pylori) bacteria.

• Smoking and regular alcohol intake.

• Diet high in salty, pickled, or smoked foods, and low in fruits/vegetables.

• Obesity and chronic gastritis (stomach inflammation).

• Pernicious anemia, family history of stomach cancer, certain genetic syndromes (FAP, Lynch, HDGC).

Prevention

• Maintaining a healthy diet rich in fruits and vegetables, low in processed and salty foods.

• Quitting smoking and limiting alcohol consumption.

• Treating and eradicating H. pylori infection.

• Regular screening for those with a strong family history or hereditary cancer syndromes.

• Managing chronic gastritis and anemia appropriately.

Early-stage detection is key but challenging due to vague initial symptoms. Persistent digestive issues, unexplained weight loss, and abnormal bleeding warrant medical evaluation
