Surgery is the first treatment for cervical cancer, but for early stage patients, when cancer cells have not metastasized and spread, surgery can directly remove the tumor and patients can have a longer survival period, but surgery is not suitable for patients who are old, have poor physical condition, have advanced cachexia and have multiple metastases. In clinical practice, not only surgery, but also radiotherapy and Chinese medicine are common treatments for patients. The patient’s physical condition, the treatment method used, and the development of the disease are the main factors related to how long the patient can live. Active treatment is the key for patients. Although radiotherapy is the main treatment method for cervical cancer, it has great toxic side effects, which can kill cancer cells and damage normal cells at the same time, leading to the decrease of immunity and damage of various body functions, which seriously affects the survival quality of patients. the quality of survival. Selenium supplementation is one of the ways often used in medicine to improve the side effects of radiotherapy and improve the quality of life of patients. After radiotherapy, patients can regularly and quantitatively take biological preparations such as chewable selenium tablets and organic malt selenium, which can improve the blood selenium level in a short time.
