Surgery for ganglion cell tumor usually takes 3~8 hours, and the specific time is related to the size of the tumor, the location of the tumor and the tissues and organs around the tumor. Before ganglion cell tumor surgery, we need to make a comprehensive diagnosis of the patient’s specific situation and judge according to the situation. If the tumor has not invaded the surrounding tissues and organs, it is relatively easy to do the surgery to remove the tumor, which takes about 3 hours. If the tumor has invaded the surrounding tissues and organs, such as the spinal cord, liver, spleen, kidneys, etc., or has encircled the blood vessels and invaded the surrounding tissues and organs, then the surgery should be postponed, and pre-operative chemotherapy should be conducted to shrink the tumor before the surgery. Surgery can take up to 8 hours or even longer. If a ganglion cell tumor is present, choose a regular hospital for surgery and consult a neurosurgeon for specific surgery times.
