The advantages of the radiofrequency knife are the simultaneous tracking of the tumor, the absence of wounds during the treatment, etc. The disadvantages are that it is more expensive and that it can only be used if there are indications. The advantage of the radiofrequency knife is that it can track the tumor synchronously. Thousands of beams of light are directed at the tumor to destroy tumor cells and reduce damage to normal tissue. Secondly, RFK can also target multiple tumors at the same time, and there is no wound or anesthesia during the treatment, which reduces the patient’s pain and shortens the recovery period. The disadvantage of Radio Wave Knife is that it is more expensive. Since this technology is more high-end, the price is around 30,000 to 60,000 RMB. Secondly, not all tumor patients are suitable for Radio Wave Knife treatment. If they suffer from esophageal cancer, intestinal cancer and other digestive tract tumors, Radio Wave Knife treatment is not recommended to prevent perforation and ulceration during treatment. If patients want to undergo Radio Wave Knife treatment, it is recommended to consult doctors in hospitals to judge whether their conditions are suitable for Radio Wave Knife treatment.
