About hereditary gastric cancer

About 2% to 5% of gastric cancers are hereditary. 1

If you have 1 close relative with gastric cancer, your chance of getting gastric cancer is 3 times higher than the general population. 2

If you have tested positive for a gastric cancer gene mutation, it does not mean you definitely will have gastric cancer. However, your chance of getting gastric cancer will be higher than the general population.

What can you do if you belong to the high-risk population?

  • Start gastric cancer screening tests as soon as possible
  • Screen for gastric cancer more frequently
  • Closely watch out for any gastric cancer symptoms
  • Learn about options that reduce gastric cancer risk

The survival rate of gastric cancer be increased two-fold by early diagnosis.
