Brain lymphoma may affect speech function. If the condition of brain lymphoma is more serious, it will often lead to the damage of brain nerve function, which may easily lead to edema of brain cells, thus affecting the language function, vision and memory and other functions to a certain extent, leading to language dysfunction, and may also cause the danger of memory loss, vision loss or even blindness. Once the brain lymphoma is diagnosed, the patient should cooperate with the doctor to take treatment in time. If the patient is able to take surgical treatment, he should try his best to take further chemotherapy or radiotherapy after surgical resection. If surgery is possible, try to have further chemotherapy or radiotherapy after surgery. Some patients who cannot be treated with surgery can be treated with chemotherapy or targeted drug therapy, and the symptoms can be improved through the treatment.
