The question of how long can patients live after tumor treatment has been a concern for patients nowadays. In fact, we can take adjuvant treatment after traditional treatment can improve the effect of treatment. A successful tumor surgery can enhance the survival rate of patients or even achieve a cure, but this is not the only factor. Regarding the influence of life expectancy after tumor treatment, it is also influenced by whether it is the best time for treatment, pre-surgery and post-surgery care, patient’s mentality, patient’s physical function and other factors. Among them, the clinical manifestation of tumor is closely related to the location, size, whether it is compressing, invading the neighboring organs and whether there is metastasis. Surgery, radiotherapy and chemotherapy are known as the “killer apps” of cancer treatment, and are also the more common cancer treatment methods in clinical practice. Surgery for cancer treatment: Although local tumor tissue can be removed, metastatic cancer cells cannot be removed, and many patients find lung metastasis and bone metastasis soon after surgery, which is very painful. Radiotherapy: There are also strict constraints in treatment. Some cancers are not sensitive to radiotherapy, so the treatment is ineffective and the side effects cause serious damage to the body, destroying the immune system and giving cancer cells the opportunity to “resurface”. ”Incomplete treatment, metastasis, recurrence, pain and side effects” are the disadvantages of conventional surgery and radiotherapy, which are also the root causes of reducing patients’ quality of life and shortening their survival period. To solve the problems of tumor metastasis and recurrence, improve patients’ quality of life and reduce the toxic side effects of conventional treatment has become an urgent problem in tumor treatment.
