In short
India has no national stomach cancer screening programme. A check is offered to people with a named reason. It is not offered by age alone.
Korea and Japan check whole populations with a scope because the disease is common there. Indian numbers do not support the same plan.
Treating H. pylori is the one step that lowers the risk itself. Everything else finds a cancer early. It does not stop one from starting.
The check is a scope test with biopsies from set places in the stomach. Not only from the areas that look wrong.
A clear scope test is reassuring, not an all-clear. New weight loss, vomiting or food sticking needs a fresh look. Whatever the last report said.
Screening is the first step of the stomach cancer pathway. What happens when a check does find cancer, from staging to the operation, is on the main stomach cancer treatment in Ahmedabad page.
Screening means testing people who feel well. It earns its place only when the disease is common enough to be worth looking for on a large scale.
Two countries do it. Korea offers a scope test, or an upper-gut barium study, every second year from the age of forty. Japan offers the same from the age of fifty. In both, most stomach cancers are now found early.
| Country | What is offered |
|---|---|
| Korea | A national programme since 1999. A scope test or a barium study every second year, from the age of forty. |
| Japan | A national programme since 2016. A scope test or a barium meal every second year, from the age of fifty. |
| United States and Europe | No population screening. Checks are offered only to named high-risk groups. |
| India | No national programme. Most stomach cancer here is found after symptoms have begun. |
Three things hold those two programmes up. The disease is common in both countries. There are enough scope units to test a whole country. Testing at work is an old habit there. None of the three holds across India.
Parts of north-east India, Mizoram and Manipur among them, carry as much stomach cancer as East Asia. Small trial programmes have run there. None has yet been scaled up.
Instead of screening everyone, a check is offered to people with a named reason. Six groups account for almost all of them.
Dr Harsh Shah explains what screening means, and why it is offered by reason and not by age alone.
Alarm symptoms are a separate matter. They are not screening at all. Weight loss, a low haemoglobin, food sticking, or new acidity after the age of forty-five mean a scope test now. Which tests follow once something is seen is set out on the page about the tests in order after an endoscopy.
This germ lives in the stomach lining of a large part of India. A long infection inflames the lining and thins it. Over decades that can end in cancer. Clearing the germ lowers the risk.
Anyone with acidity for years should be tested once. A parent, brother, sister or child of a stomach cancer patient should be tested too. Symptoms or no symptoms.
| Test | What it involves |
|---|---|
| Stool antigen test | A stool sample. No scope test is needed. |
| Urea breath test | Breathing into a tube before and after a drink. |
| Biopsy taken at the scope test | A small piece of the lining, tested in the same room. |
| Blood antibody test | Not used to decide treatment. It stays positive long after the germ has gone. |
Treatment is two antibiotics with an acid-reducing medicine. All three are taken together for two weeks. The germ resists one of those drugs often in India. So many centres start with a four-drug course that adds bismuth. Finish the course exactly as written. A half-taken course leaves a harder germ behind.
Clearance is then confirmed, usually about a month later. The acid-reducing medicine is stopped two weeks before that test. A treatment never checked is not a treated infection.
These are changes in the lining of the stomach, not cancer. They sit on a slow road towards it. They are the commonest reason a well person is put on a set of timed checks.
How often depends on two things. How much of the stomach is involved, and whether a close relative had stomach cancer.
| What the biopsy showed | What follows |
|---|---|
| Mild change in one part of the stomach only | No repeat check is needed. |
| Wide change, in both the lower and the upper stomach | A check about every three years. |
| Wide change, with stomach cancer in a close relative | A check every one to two years. |
| A flat area of low-grade change | A repeat check, with the area photographed and mapped. |
| A visible lesion, or a high-grade change | Removal through the scope, or an operation where that is not possible. |
The report usually grades this change in stages. Only the top two stages need a set of timed checks. The lower ones do not.
In pernicious anaemia the body attacks its own stomach lining. The lining is thin in everyone who has it. A check about every three years is reasonable.
A stomach whose lower part was removed for an ulcer, decades ago, is different. What remains is bathed in bile from the small bowel. The lining changes slowly.
Checks on a stomach that was cut begin ten to fifteen years after that surgery. They then repeat every one to two years, going by how the rest of the lining looks.
A few families carry a gene change that lifts stomach cancer risk far above usual. The commonest is CDH1. It causes a family form of diffuse stomach cancer. Others come packaged with bowel syndromes.
| Gene or syndrome | Checks start | How often |
|---|---|---|
| CDH1 | Age eighteen to twenty | Every year, with many biopsies, while the choice about an operation is made. |
| CTNNA1 | Age twenty to thirty | Every one to two years. |
| Lynch syndrome | Age thirty to thirty-five | Every three to five years, at the same time as the bowel scope. |
| The family bowel polyp syndrome (FAP) | Age twenty-five to thirty | Every one to three years. The first part of the small bowel is looked at too. |
| Peutz-Jeghers syndrome | Age eight to ten | Every two to three years. |
| Juvenile polyposis | Age fifteen | Every one to three years, with the bowel scope. |
Who should be offered a gene test, how the counselling runs, and when a risk-cutting operation is discussed: all that sits on the page about hereditary gastrointestinal cancer syndromes. This page is about the check itself.
It is done under light sedation. It takes longer than a routine scope test for acidity. That extra time is the whole point of it.
This matters most in CDH1 families. Their cancer grows as scattered specks under a lining that looks normal. Random biopsies miss the great bulk of early disease. A normal report is reassuring about that visit. It does not say the stomach is free of disease.
So the check in a CDH1 carrier is a bridge. It is not a stand-in for removing the stomach. It is used while the choice is being made, or when a person has said no to the operation.
In every other group, a new symptom between two checks outranks the date. Weight loss, vomiting or food sticking means a scope test now, not at the next due date.
| Step | Why it matters |
|---|---|
| Get tested for H. pylori | It is the one step that lowers the risk itself. The rest only find a cancer early. |
| Write the family history down | Two generations. Which cancer each relative had, and at what age. That decides whether a gene test is offered. |
| Find the old biopsy report | A thin or changed lining on that report alters the whole plan. |
| Ask whether any check is needed at all | Most people who are worried do not need timed checks. Being told so plainly is a result. |
| Agree the interval in writing | A date in the file is what makes a check happen. A spoken plan rarely lasts three years. |
Not on its own. A check is offered when there is a named reason: a positive H. pylori test, a close relative with stomach cancer, a family gene, an odd past biopsy, pernicious anaemia, or a stomach that was cut long ago.
Get tested for H. pylori, and treated if it is positive. Then write the family history down and bring it. A scope test may follow. That depends on how many relatives were affected, and at what ages.
It lowers the chance of a late diagnosis. It does not remove the risk. A new symptom between two checks needs a scope test then, not at the next due date.
No blood test finds stomach cancer early. The antibody blood test for H. pylori shows only past contact with the germ. It stays positive long after the germ has gone.
Stomach cancer is far commoner in Japan and Korea. Both have enough scope units to test a whole country. Indian numbers, outside a few north-eastern states, do not support the same plan.
