The cost of genetic test for stomach cancer is between 5,000 yuan and 10,000 yuan. There will be some differences in different regions, different hospitals, and different testing programs. The cost of stomach cancer genetic test is affected by the region, hospital, and specific test items. In developed areas and high grade hospitals, the cost is relatively higher; meanwhile, some genetic tests for stomach cancer only include a dozen or so basic gene tests, while others check all the genes of stomach cancer at one time (including hundreds of genes). Genetic test for stomach cancer is an important reference for judging the medication plan of stomach cancer patients, especially the treatment of targeted drugs. Because in different patients with different types of gastric cancer tumors, their sensitivity to chemotherapeutic drugs and targeted drugs is not the same, genetic testing can maximally help patients choose the right drugs for treatment, and can also help tumor patients judge recurrence, survival period and so on. Meanwhile, genetic test for stomach cancer can also find out the potential risk of having stomach cancer patients in the family, suggesting the hereditary nature of stomach cancer and guiding for eugenics. Therefore, if there are conditions, it is better to try to perfect the examination of gastric cancer gene, in order to benefit the treatment and subsequent judgment.
