Chronic lymphocytic leukemia is possible to cure after half a year, but the chance of cure is small, in the absence of therapeutic indications, may not be chemotherapy, when the therapeutic indications are reached, the patient needs to be actively in the physician’s guidance for drug treatment. Chronic lymphocytic leukemia generally has a slow development, after regular observation and effective treatment, can survive for a long time, the drugs include phenylbutyric acid nitrogen mustard, etc., but most of the patients are difficult to cure. So chronic lymphocytic leukemia for six months, there is still a possibility of cure. However, if the patient has obvious symptoms and does not receive timely treatment, which leads to faster progression of the disease, the prognosis is considered poor, so it needs to be actively treated under the guidance of a physician. The median survival time of most chronic lymphocytic leukemia patients is about 10 years, but some patients with severe disease have a relatively short survival period of only 2 to 3 years. Therefore, after the diagnosis of the disease, patients need to follow the doctor’s instructions as soon as possible to carry out standardized treatment, and do a good job of their own care, and some patients only need to be regularly reviewed, so as to prolong the survival time, or even to achieve a cure. It is recommended that patients with chronic lymphocytic leukemia take reasonable treatment measures under the guidance of doctors as soon as possible, so as not to delay the condition.
