Stomach Cancer in Young Women: More Dangerous Than Lung Cancer—Prevent It Early with a Pepsinogen Test
Stomach cancer in women under 40 is often more aggressive than lung cancer. Learn how a simple Pepsinogen II blood test can predict risk and save lives.
Hello,
This is Geomjin Gaja.
The cherry blossoms have mostly fallen, and we are entering the season of lush green leaves.
We have brought some vital health information that young women under the age of 40 must pay attention to.
Usually, when people think of stomach cancer, they assume it is a disease that affects the elderly. However, stomach cancer occurring in the younger generation, particularly in women, is notorious for having a very poor prognosis.
According to recent research in gastroenterology, it is possible to predict the probability of developing stomach cancer in advance through a simple blood test called the Pepsinogen II level.
Let’s look into the details.
Why is stomach cancer more dangerous in young women?
Stomach cancer in young women is often not the ‘intestinal type’ (which forms a distinct mass) that we commonly know, but rather the ‘diffuse type’ that spreads widely along the stomach wall.
Diffuse-type stomach cancer is difficult to detect and progresses very rapidly, spreading easily through the lymphatic system or bloodstream. Shockingly, research has revealed that for those under 40, the prognosis is even worse than that of lung cancer.
What is the Pepsinogen II test?
Pepsinogen is a precursor to an enzyme secreted by the stomach and is already a widely used diagnostic indicator in the medical community. However, this study has proven that Pepsinogen II levels are specifically and closely related to the occurrence of stomach cancer (diffuse type) in young women.
A 21-times higher risk of stomach cancer?
According to the research results, caution is required if you meet the following conditions:
Target:
Young women under 40
Conditions:
Presence of Helicobacter pylori bacteria and a Pepsinogen II level exceeding 20.
If these conditions are met, the probability of developing stomach cancer is reportedly 21 times higher than for women who do not meet them. This is analyzed to be due to a combination of genetic factors and the influence of female hormones (estrogen).
Testing Method and Cost
This test can be performed through a simple blood draw without any complicated procedures.
Where can I get it done?
It is easily available not only at large general hospitals but also at local internal medicine clinics or family medicine practices through a testing agency request.

What about the cost?
It is very affordable if covered by health insurance, and even if not covered, it can be done without much burden at around 40,000 to 50,000 KRW.
If you are a young woman who feels fearful or reluctant about undergoing an endoscopy, we recommend taking this Pepsinogen II test first. If the levels come back high, you should not hesitate to consult a specialist and undergo a gastroscopy more proactively.
Stomach cancer has a high cure rate if detected early. However, since diffuse-type stomach cancer in the youth progresses so quickly, early detection is the only way to save lives. Checking for Helicobacter pylori infection and monitoring Pepsinogen levels are small habits that can determine your healthy future.

Frequently Asked Questions
Why is stomach cancer more dangerous in young women?
Yes, it is primarily because it often manifests as diffuse-type gastric cancer. Diffuse-type gastric cancer spreads widely along the stomach wall, making it difficult to detect and progressing very rapidly. It also metastasizes easily through lymph vessels or blood, and is known to have a worse prognosis than lung cancer in women under 40.
What is the pepsinogen II test?
It is a simple blood test that predicts the probability of developing stomach cancer. Pepsinogen is a precursor to enzymes secreted in the stomach, and by checking its levels, the risk of developing diffuse-type gastric cancer, which is particularly fatal to young women, can be identified in advance.
Are there specific criteria that increase the probability of developing stomach cancer?
Yes, if a young woman under 40 has Helicobacter pylori in her body and her pepsinogen II level exceeds 20. If these conditions apply, the probability of developing stomach cancer is 21 times higher than in women who do not meet these conditions, so special attention is required.
How much does the pepsinogen test cost and where can I get it?
It costs approximately 40,000 to 50,000 won without insurance, and is cheaper with health insurance coverage. You can easily get this blood test not only at large hospitals but also at nearby local internal medicine or family medicine clinics through a referral to a testing institution.
What should I do if my pepsinogen test results are high?
You should immediately consult a specialist and actively undergo a gastroscopy. A high level indicates a high risk of stomach cancer, so it is very important not to delay endoscopy for early detection and treatment.
