The main danger of stopping chemotherapy is that the condition will easily deteriorate further, and a small number of patients will easily induce drug resistance. Chemotherapy is a common treatment method in clinic, which helps to eliminate cancer cells in the body, so as to control the condition and prolong the survival time. If a patient stops chemotherapy in the middle of the treatment, the ideal effect of chemotherapy cannot be achieved, and the cancer cells in the patient’s body are prone to further increase in value or metastasize, which will lead to further deterioration of the condition and lower the survival rate. For a small number of chemotherapy patients, those who stop treatment in the middle of the course are prone to drug resistance, which also affects the effect of chemotherapy and needs to be taken seriously. As chemotherapy also causes damage to normal cells, inducing nausea and vomiting, hair loss and other symptoms, chemotherapy patients should adjust their mindset and actively cooperate with doctors to use chemotherapy drugs throughout the treatment in order to control the progress of the disease. It is recommended to consult regular hospitals for chemotherapy, and during the chemotherapy period, it is necessary to strengthen the skin and dietary care to ensure a balanced intake of nutrients to meet the needs of the body and improve immunity.
