How often or how long is chemotherapy appropriate?

The number and duration of chemotherapy varies according to the patient's specific condition, cancer type, stage and individual differences, so there is no uniform answer.

Generally speaking, the cycle and number of chemotherapy are determined according to the doctor's advice and the patient's specific situation.

Therefore, the number or duration of chemotherapy should be determined according to the patient's specific situation. It is recommended that patients be treated under the guidance of the doctor.
