Introduction

Stomach cancer, also known as gastric cancer, is a disease where malignant (cancerous) cells form in the lining of the stomach. The stomach is a vital organ in the digestive system that breaks down food and absorbs nutrients. Stomach cancer often develops slowly over many years and can be difficult to detect in its early stages.

Studying stomach cancer is important because it is a significant cause of cancer-related deaths worldwide. Early detection and treatment can greatly improve survival rates. Recent developments in treatment, such as targeted therapies and immunotherapies, offer new hope by specifically attacking cancer cells without harming normal cells.

Statistics

Incidence: Approximately 1 in 111 people will develop stomach cancer in their lifetime.

Mortality: Stomach cancer is the fifth most common cancer and the third leading cause of cancer death globally.

Gender Disparity: Men are twice as likely as women to develop stomach cancer.

Geographic Variation: Higher rates are seen in East Asia, Eastern Europe and parts of South America.

Risk Factors and Prevention

a. Known Risk Factors

Age: Most cases occur in people over 55 years old.

Gender: Men are at higher risk than women.

Diet: Consuming a diet high in smoked, pickled, or salty foods can increase risk.

Helicobacter pylori Infection: A common stomach bacterium that can cause ulcers and increase cancer risk.

Family History: Having close relatives with stomach cancer raises your risk.

Smoking: Doubles the risk of developing stomach cancer.

Previous Stomach Surgery: Can increase risk due to changes in the stomach environment.

Certain Medical Conditions: Such as chronic gastritis or harmful anemia.

b. Prevention

Healthy Diet: Eat plenty of fresh fruits and vegetables; reduce intake of smoked and salty foods.

Treat H. pylori Infection: Seek medical treatment if diagnosed with this infection.

Quit Smoking: Stopping smoking reduces risk significantly.

Limit Alcohol Consumption: Reducing alcohol intake may lower risk.

Regular Medical Check-Ups: Especially if you have risk factors or persistent stomach issues.

Screening

Upper Endoscopy (EGD): A flexible tube with a camera is inserted through the mouth to view the stomach lining and take tissue samples.

Benefits: Direct visualization and ability to perform a biopsy.

Risks: Mild discomfort, rare complications like bleeding.

Biopsy: Tissue samples taken during endoscopy are examined for cancer cells.

Imaging Tests: CT scans, PET scans, and X-rays help determine the extent of cancer.

Blood Tests: Check for anemia or specific tumor markers.

Screening for stomach cancer isn’t common in areas with low incidence. However, in high-risk regions or individuals with significant risk factors, doctors may recommend screening.

Symptoms and Early Warning Signs

Indigestion or Heartburn: Persistent discomfort or burning sensation.

Loss of Appetite: Feeling full quickly after starting to eat.

Nausea or Vomiting: Sometimes with blood.

Abdominal Pain: Particularly in the upper abdomen.

Unexplained Weight Loss: Losing weight without trying.

Fatigue or Weakness: Often due to anemia from internal bleeding.

Blood in Stool: Which may appear dark or tarry.

These symptoms can be caused by conditions other than stomach cancer, like ulcers or infections. If you experience any of these symptoms persistently, it’s important to consult your healthcare provider.

Overview of Treatment Modalities

Comparing Treatments

Treatment	Mechanism	Side Effects	Efficacy (5-Year Survival Rate)	Notes
Surgery	Removes cancerous tissue	Pain, digestion changes	Up to 68% if cancer is caught early	Most effective for early-stage cancer
Chemotherapy	Inhibits cancer cell growth	Nausea, hair loss, fatigue	Improves survival when combined with surgery	Used for advanced or spread cancers
Radiation	Destroys cancer cells with radiation	Skin irritation, fatigue	Enhances effectiveness when combined	Often used with chemotherapy and surgery
Immunotherapy	Boosts immune response	Fatigue, rash	Varies; promising for advanced stages	Suitable for specific types of stomach cancer
Targeted Therapy	Attacks specific cancer cells	Diarrhea, hypertension	Effective for cancers with certain markers	Requires genetic testing of tumor cells
