According to the International Agency for Research on Cancer (IARC), each year there are about 870,000 new cases and 650,000 deaths from stomach cancer. There are many opinions that people with blood type A will have a higher risk of stomach cancer, so is this opinion correct or not?

Stomach cancer is a common disease, with the second leading cause of death in the world. The early diagnosis and treatment of stomach cancer will help improve the mortality rate in patients. Currently, the pepsinogen test is the noninvasive screening solution used for risk assessment and early detection of gastric cancer in at-risk patients.

Stomach cancer screening is a matter of great interest because this is the most common type of cancer among gastrointestinal cancers. Around the world, every year, about 600,000 - 700,000 new cases of stomach cancer are detected. It is the second most common cause of cancer death worldwide.

According to the World Health Organization (WHO) 2018, stomach cancer is the most common cancer, after liver cancer and lung cancer in frequency, accounting for 10% of all cancers.
