Asia (mainly China) has the highest number of registered gastric cancer cases (approximately 820,000 new cases and 580,00 deaths), with less than 20% survival rate in 5-yearan as estimated.

Tumor markers are specific substances that can reflect the occurrence and development of tumors and tumor marker level helps to monitor patient’s response to treatment.Tumor markers are present in the tissues, body fluids and excreta of tumor patients, and can be detected by immunological, biological and chemical methods.

Precision medicine is a medical model based on individual-specific data such as genetics, biomarkers, and environmental factors, combined with advanced scientific and technological means (such as gene sequencing, biochip technology, data mining, artificial intelligence, etc.) for the prevention, diagnosis, treatment, and monitoring of diseases to be personalized, precise and customized. Compared with the traditional patient treatment mode, it pays more attention to the influence of individual factors, provides more accurate, more effective, and safer treatment programs, and has the advantages of strong guidance, high effectiveness, and high resource utilization rate.

Chronic disease and its ongoing condition usually lasts for months or years and cannot be completely cured. They include heart disease, diabetes, high blood pressure, asthma, and cancer.

The last week of April is the World Immunization Week, which aims to promote vaccination and protect people of all ages from disease. Vaccination saves countless lives and is recognized as one of the most successful and cost-effective health interventions.

Point-of-care testing (POCT) is the rapid testing of biological samples (such as blood, urine, saliva, breath gas, etc.) at the patient's side, using simple instruments or reagents, and results can be obtained within minutes to hours. The test can help physicians make timely diagnosis and treatment plans, and provide important information to improve treatment outcomes in an emergency setting.

According to the global cancer data of 2020, released by the International Agency for Research on Cancer (IARC) of the World Health Organization, China had 4.57 million new cases and 3 million deaths in 2020, ranking No.1 in the world. Lung cancer, colorectal cancer, stomach cancer, breast cancer and liver cancer are the most common cancers in China. According to statistics, one third of cancers can be prevented by keeping good living habits and early screening. "Early detection, early diagnosis and early treatment" might reduce the incidence and mortality of cancer, and save lives.
