Among the various types of cancer, prostate cancer is very special and has a subclinical form. With the support of clinical research evidence, medical doctors have proposed that a portion of patients with early-stage prostate cancer can be treated without any treatment for the time being, just observing the changes and progress of the disease and then treating it when appropriate, and called this “treatment” without any treatment “This is called “standby treatment” of prostate cancer. What kind of early stage prostate cancer patients can be treated on a standby basis? This requires a combination of factors such as the clinical stage of the tumor, the degree of differentiation, the patient’s physical condition and life expectancy, and socioeconomic status. However, these patients should be closely followed up with a comprehensive medical evaluation every 3 months to 6 months. If tumor progression is observed, which may be potentially dangerous to the patient, timely treatment measures are still needed. The age of the tumor patient is another major factor in determining treatment options. Most patients younger than 65 years of age who are not given treatment will eventually die from prostate cancer. Therefore, radical surgery should be performed for patients with limited prostate cancer who are younger than 70 years old and have an expected survival of greater than 10 years. Radical prostate cancer treatment for early stage prostate cancer is satisfactory, but surgery is after all traumatic. Advances in radiotherapy technology have brought new options for the treatment of some patients, including three-dimensional conformal external irradiation and particle implantation radiotherapy, etc. Studies have shown that the 5-year survival rate of radiotherapy for early stage prostate cancer is comparable to that of radical surgery. For patients with advanced prostate cancer, it has been medically proven that there is no longer any possibility of a complete cure. However, fortunately, prostate cancers themselves have a very fatal weakness, which is that they depend on androgens for nourishment for their growth. Once the androgens are removed, most prostate cancers gradually shrink or even disappear and can be maintained for a long time. The most important thing is that it is not just a matter of the size of the body, but also of the size of the body.
