Usually, patients need to wait until their wounds are completely healed before they can undergo postoperative chemotherapy, which is usually about 3-4 weeks after surgery, but each person’s situation is different and it is not possible to make a generalization. As there are many toxic side effects of chemotherapy drugs, and many systemic discomfort symptoms may occur during chemotherapy, which may also affect the effect of surgery and recovery, it is usually chosen to recover for a period of time after surgery before chemotherapy is administered. In most patients, chemotherapy can be administered about one month after surgery, when the wound has basically healed. However, the duration of chemotherapy varies depending on a number of factors, including the patient’s specific physical condition, and cannot be generalized. It may be extended for some people. Patients receiving chemotherapy after surgery should actively cooperate with the treatment and maintain a good psychological quality, which is also conducive to the recovery of the disease.
