Gastric Cancer (Stomach Cancer): Symptoms, Causes, Diagnosis & Treatment

Introduction

Gastric cancer, also known as stomach cancer, develops when abnormal cells grow uncontrollably in the lining of the stomach. In India, including cities like Hyderabad, the number of cases is increasing due to lifestyle changes, dietary habits, and delayed diagnosis. Although its incidence has declined in some regions, this disease remains one of the leading causes of cancer-related deaths worldwide.

Early detection plays a crucial role in improving survival rates. However, many patients in Hyderabad and nearby areas seek medical help only at advanced stages because early symptoms are often mild and easily ignored.

What Is Stomach Cancer?

This condition begins in the inner lining of the stomach and may spread to deeper layers over time. The most common type is adenocarcinoma, which accounts for nearly 90% of cases. Other rare forms include lymphoma, gastrointestinal stromal tumors (GIST), and neuroendocrine tumors.

Early Symptoms

In the early stages, stomach tumors may not cause noticeable symptoms. When symptoms appear, they are often mistaken for common digestive problems.

Common Early Symptoms

  • Indigestion or heartburn

  • Bloating after meals

  • Mild nausea

  • Loss of appetite

  • Unexplained weight loss

Advanced Symptoms

  • Difficulty swallowing

  • Persistent vomiting (sometimes with blood)

  • Black or tarry stools

  • Fatigue due to anemia

If these symptoms persist for more than two weeks, medical evaluation is essential.

Causes and Risk Factors

There is no single cause, but several factors increase the risk.

Common Risk Factors

  • Helicobacter pylori (H. pylori) infection

  • Smoking and tobacco use

  • Excessive alcohol consumption

  • Diet high in salty, smoked, or processed foods

  • Family history of stomach malignancy

  • Chronic gastritis

  • Obesity

  • Age above 50 years

Diagnosis

Doctors may recommend the following tests to confirm the condition:

  • Upper endoscopy – to examine the stomach lining

  • Biopsy – to confirm the presence of cancer cells

  • CT scan or PET scan – to detect spread

  • Endoscopic ultrasound (EUS) – to assess tumor depth

  • Blood tests – to check anemia and overall health

Stages

The disease is staged from Stage 0 to Stage IV, depending on how deeply it has invaded and whether it has spread.

  • Stage 0: Cancer limited to the inner lining

  • Stage I–II: Spread to deeper layers or nearby lymph nodes

  • Stage III: Extensive lymph node involvement

  • Stage IV: Spread to distant organs such as the liver or lungs

Treatment Options

Treatment depends on the stage, tumor location, and the patient’s overall health.

1. Surgery

Surgical removal of part or all of the stomach (gastrectomy) is the most effective treatment for early-stage disease.

2. Chemotherapy

Chemotherapy uses anti-cancer drugs to destroy abnormal cells and may be given before or after surgery.

3. Radiation Therapy

Radiation uses high-energy rays to destroy malignant cells, often combined with chemotherapy.

4. Targeted Therapy

Targeted drugs attack specific tumor markers, improving treatment precision and reducing side effects.

5. Immunotherapy

Immunotherapy helps the body’s immune system recognize and fight cancer cells more effectively.

Prevention

Although not all cases are preventable, the risk can be reduced by:

  • Treating H. pylori infection early

  • Eating a balanced diet rich in fruits and vegetables

  • Avoiding smoking and excessive alcohol consumption

  • Maintaining a healthy weight

  • Regular medical check-ups for high-risk individuals

When to See a Doctor

If you live in Hyderabad or surrounding areas and experience persistent indigestion, unexplained weight loss, stomach pain, or difficulty swallowing, consult an experienced gastroenterologist or oncologist immediately. Early diagnosis at a well-equipped hospital or gastro clinic in Hyderabad can significantly improve treatment outcomes.

Conclusion

This is a serious condition, but early detection and modern treatment options available in Hyderabad have significantly improved patient outcomes. Awareness of symptoms, risk factors, and timely consultation with a specialist can make a critical difference. Do not delay seeking expert care—early action saves lives.
