As a predator of the body, tumor has the principle of "you are mine, I am still mine", and also gives full play to the essence of the word "grab", grabbing nutrition, energy, land, and being king all over, which invisibly harvests people's lives and makes people talk about cancer. Where there is oppression, there is resistance. Humans naturally don't want to sit still, but have been trying. Surgical resection, systemic chemotherapy, radiotherapy and other methods have indeed brought good news to tumor patients to some extent, but this single "destructive" treatment has many disadvantages, and the life and quality of life of patients can not be truly guaranteed.

In order to bring the miracle of life to cancer patients, in the process of countless times of fighting cancer, researchers who have accumulated most of their experience are slowly moving towards the general direction of tumor precision medicine. Nowadays, cancer treatment is gradually changing from "disease" treatment to "gene" treatment. In the past, the empirical and monotonous medication mode was gradually broken, and personalized medication was taking its place. Yes, accurate cancer care has entered people's field of vision. Precision medicine. Let cancer no longer be a terminal disease! Since 20 15, US President Barack Obama has vigorously promoted the concept of precision medicine, which has attracted global attention. Precision medicine comes from personalized medicine, which is based on personal genome information, combined with protein genomics, genomics and other information, aiming at the molecular bio-pathological characteristics of patients, to formulate personalized diagnosis and treatment strategies.

The molecular genetic heterogeneity of tumors is great, and the sensitivity and drug resistance of different tumor individuals are different. Sometimes, even cancer patients with the same pathological type have different reactions to anticancer drugs. In order to avoid unnecessary or destructive treatment of patients, the concept of precision oncology came into being. Precision oncology aims to solve the heterogeneity between tumors and within tumors, and uses various types of data to divide patients into groups that are most likely to respond to treatment.

The cornerstone of accurate tumor treatment is to find the biomarkers related to it, such as DNA, RNA, protein, metabolites or microorganisms, according to the differences of individual molecular genetics, and on this basis, determine the drug treatment targets and interference related ways. Many researchers are committed to discovering susceptible oncogenes, mutant tumor suppressor genes and other related tumor susceptibility factors in the process of tumor occurrence.
