Overview
Stomach cancer (SC) accounts for about 4.5% of all cancer cases in India, with approximately 64,000 new cases reported each year out of
1.4 million total cancer incidences. It is more common in males than females, with a ratio of 2.3 to 1, and its occurrence is notably higher in
the southern and north-eastern regions of the country. When diagnosed at an early stage, the five-year survival rate for Stomach cancer
can reach up to 70%. As with many other cancers, early detection is vital, as it improves survival rates, expands treatment options, and
enhances the quality of life. However, because early-stage stomach cancer often presents with few or nonspecific symptoms, timely
screening and detection are crucial.
Why Screening is Essential
Early-stage stomach cancer can cause symptoms such as heartburn, indigestion, changes in appetite, nausea, or vomiting. An Early Detection Program (EDP) is essential for
identifying the disease before it advances or spreads. The primary goal of such a program is to detect stomach cancer even before symptoms appear or while it remains in a
localized, treatable stage. Early detection allows for timely intervention, which can
reduce the need for extensive surgery or prolonged treatment and ultimately improve the
patient’s quality of life.
Benefits:
- Improved Survival Rates: Early detection = higher survival rates. Early-stage stomach cancer has a much higher 5-year survival rate.
- Reduce Mortality: Risk based evaluation helps in lower deathrates from stomach cancer, particularly in high-risk populations.
- Cost-Effectiveness in High-Risk Groups.
- Some cases when detected very early might not need any systemic chemotherapy.
- Very early or precancerous lesions may be managed with endoscopy alone, without surgery or chemotherapy.
How It Works
- Physical Examination : As part of the initial evaluation, the clinician checks the abdomen for masses, examines the lymph nodes for any enlargement, and assesses general health signs such as weight loss, fatigue, or paleness.
- Upper Endoscopy (Esophagogastroduodenoscopy, EGD):
A flexible tube with a camera is inserted through the mouth to examine the esophagus, stomach, and upper part of the small intestine. This allows the clinician to:
1. Visually inspect the inner lining of the stomach for suspicious areas.
2. Directly identify early lesions
Who Should Get Screened for Stomach Cancer?
- Older Adults and Men: Individuals aged 60 years or older, and men (who are at higher risk than women)
- Infection and Inflammation Risks: Those with long-term Helicobacter pylori infection or chronic gastritis.
- Family and Genetic Factors: People with a family history of stomach cancer or genetic conditions such as Hereditary Diffuse Gastric Cancer (HDGC) or Familial Adenomatous Polyposis (FAP).
- Lifestyle and Dietary Risks: Individuals with a high intake of salty, smoked, or pickled foods, or those who smoke or are obese
- Other Risk Factors: Those with a history of stomach surgery, occupational exposure to coal, rubber, or metal industries, or blood type A, which carries a slightly higher risk.
FAQ’s
1. What is the purpose of the early detection program for stomach cancer?
The goal is to detect stomach cancer early, before advanced symptoms appear, to improve treatment outcomes, survival rates, and
quality of life.
2. Who should consider an early detection program (EDP) for stomach cancer?
EDP is generally recommended for individuals at high risk, such as those aged 60 or above, with a family history of stomach cancer,
Helicobacter pylori infection, chronic gastritis, smoking history, high-salt diet, or genetic syndromes like Lynch syndrome and HDGC.
3. Are there routine screening tests for stomach cancer?
Routine screening is not recommended for the general population, but upper GI endoscopy is advised for high-risk individuals.
4. Can stomach cancer early detection prevent stomach cancer?
Screening may not prevent the disease but helps detect it at an early stage, when it is more treatable and has a better prognosis.
5. How often should high-risk individuals be screened?
Screening frequency depends on risk factors and findings. For high-risk individuals, an endoscopy may be advised every 1–3 years,
as per a doctor’s recommendation.
6. Does early detection improve survival?
Yes, detecting stomach cancer early—before it spreads—significantly increases treatment success and long-term survival rates.
7. Is stomach cancer treatable?
Yes. With early detection, stomach cancer can often be treated effectively with surgery, chemotherapy, radiation, or a combination of
these approaches.
8. What if I have indigestion or persistent stomach discomfort?
Indigestion doesn’t always mean cancer, but persistent or worsening symptoms, especially in older individuals should be evaluated.
Your doctor may recommend endoscopy or further tests if risk factors are present.
9. Are there lifestyle changes that reduce my risk?
Yes. Quitting smoking, reducing intake of salty or smoked foods, eating a diet rich in fruits and vegetables, treating H. pylori infections,
and maintaining a healthy weight can all lower your risk..
