You have some risk factors. Review your lifestyle and keep regular screening in mind.
Guideline grouping based on the ABC screening concept
Grouping cannot be determined (insufficient information)
ABC screening requires both H. pylori antibody and pepsinogen tests.
Score breakdown
| Factor | Points |
|---|---|
H. pylori infection status unknown If you have never been tested, checking with an antibody test is recommended. | +1 |
Presence of atrophic gastritis unknown ABC screening (pepsinogen test) can assess the state of the gastric mucosa. | +1 |
Age 50 to 59 An age group eligible for screening. | +1 |
Slightly high salt intake Try to cut down on salt. | +1 |
Recommended actions
- Get an H. pylori test (such as an antibody test) to check for infection
- Assess the state of the gastric mucosa with ABC screening (pepsinogen test)
- Cut down on salt and avoid salted foods
- Get regular screening such as gastric endoscopy appropriate for your age
How it works
- Well-known risk factors such as H. pylori (Helicobacter pylori) infection, presence of atrophic gastritis, age, smoking, salt intake, vegetable and fruit intake, and a close relative's history of stomach cancer are scored, and the total score is used to show relative risk in four bands: lower, moderate, higher, and very high.
- The scoring weights H. pylori infection and atrophy of the gastric mucosa (atrophic gastritis) heavily, as these are considered the most important background of stomach cancer in Japanese people, and adds points for smoking, high salt intake, aging and so on, based on an original simplified rule. It does not calculate an absolute probability of onset.
- Based on the ABC screening concept (classification into Groups A to D by combining an H. pylori antibody test and a pepsinogen test), it shows a guideline for the group you are likely to fall into from your inputs. Actual group determination requires blood tests at a medical facility.
- If your H. pylori infection status or the presence of atrophic gastritis is unknown, taking an antibody test to check for infection or a pepsinogen test leads to a more accurate understanding of your risk.
- Cutting salt, quitting smoking, eating vegetables and fruit, eradicating H. pylori, and regular screening such as gastric endoscopy appropriate for your age are considered helpful for preventing and detecting stomach cancer early.
- This tool is a guide based on general risk factors and is not a diagnosis or medical service. Always consult a doctor for health-related decisions.
