Neurological recidivism refers to the patient’s nerve tissues or cells being invaded and damaged by other tissues, resulting in certain abnormalities or damage to the nerve function. Neurological recidivism is mostly seen in patients with middle to late stage malignant tumors. Malignant tumors are prone to spread and invade the whole body or the surrounding tissues and organs, and when invading the nerve-related tissues and cells, it can affect the normal function of the patient’s nerve tissues and cells, which will lead to some neurological abnormalities, such as sensory abnormalities, which is referred to as neurological recidivism. When nerve recurrence occurs, patients should go to the neurology department or oncology department of regular hospitals as soon as possible, explain their situation in detail to doctors, and cooperate with doctors to complete the necessary examinations, such as CT, blood routine, blood biochemistry, etc., so as to clarify the causes of nerve recurrence as soon as possible, and then carry out treatment in a timely manner, so as to avoid further deterioration of the condition.
