What is the harm of stopping chemotherapy halfway

Stopping chemotherapy halfway can bring serious harm, including the possibility of tumor cells rebounding, increasing the risk of drug resistance, affecting the patient's chances of survival, and possibly causing new complications. 1. Tumor cells may rebound Chemotherapy inhibits or kills tumor cells through drugs, but if stopped halfway, tumor cells may re-proliferate rapidly, and the effects of previous chemotherapy may be offset, resulting in rapid progression of the disease. Irregular chemotherapy may make tumor cells more susceptible to drug resistance, making it difficult to effectively control tumor growth and spread. Complete chemotherapy courses are often carefully designed and validated, and stopping midway may not achieve the expected treatment goals, thus adversely affecting the long-term survival of patients and reducing the survival rate and quality of life of patients. Interruptions in chemotherapy that may trigger new complications may lead to changes in the controlled condition, causing new symptoms or exacerbating existing symptoms, causing more pain and discomfort to the patient. Discontinuation of chemotherapy is a cautious situation. Unless there is a very clear and necessary reason, it is necessary to follow the chemotherapy regimen prescribed by the doctor as much as possible to ensure the best treatment effect and survival prognosis.
