Most early stage prostate cancers can be cured by radical surgery, but are there other ways to cure early stage prostate cancer besides radical surgery? Radical prostate radiation therapy and prostate freezing can also cure early stage prostate cancer. The advantage of radical radiotherapy over radical surgery is that the patient does not have to go under the knife, but the disadvantage is the long treatment time (about 2 months) and the difficulty in dealing with distant or chronic radiotherapy reactions (radiation cystitis or proctitis) once they occur. The advantage of prostate cryotherapy is that the treatment time is short (one treatment is enough, which is shorter than the hospital stay for radical surgery), and it is a real minimally invasive treatment, so there is less trauma and less complications, especially no long-term complications, and the effect of tumor control is no less than that of radical prostate cancer surgery, so it is especially suitable for those patients who are too old and poor to tolerate surgery or radiotherapy, and also those who do not want to undergo surgery or radiotherapy. It is also an ideal treatment option for patients with prostate cancer who do not want to undergo surgery or radiation therapy. Prostate cryotherapy has been used in foreign countries for more than 10 years, but it has rarely been used in China due to equipment and technology.
