Prostate cancer is a disease of older men. Globally, the incidence is increasing. It is the most common cause of lethal cancer in men. Prostate cancer is curable in its early stages, but rarely causes or has no clinical symptoms. When clinical symptoms appear, the opportunity for good treatment has been lost. Although the use of serum PSA, or prostate cancer antigen, has enabled many patients to detect the possibility of prostate cancer at an early stage exists. It is possible to get early diagnosis and treatment. However, most patients with prostate cancer that develops advanced metastasis die from prostate cancer. I. First, let’s talk about PSA PSA is a glycoprotein, which is a substance secreted by the glandular cells of the prostate body and the epithelium of the glandular ducts. The relationship between PSA value and prostate cancer and prostate hypertrophy: the normal value of PSA is less than 4.0 mg/ml, and the majority of prostate hypertrophy is less than 4.0 mg/ml. The PSA value of 22.8mg/ml can be used as a diagnostic indicator of prostate cancer. If the PSA value is greater than 54.8mg/ml, it is definitely diagnosed as prostate cancer. Other diagnosis 1. When PSA is greater than 4.0-10.0mg/ml, rectal finger examination is required. 2. When the ratio of free PSA to PSA is less than 0.16, it can be considered as possible prostate cancer. 3.MRI film examination has some reference value. 4.Pathological examination of prostate puncture biopsy. Treatment 1. Vigilance concept: When the above examination results are not sure for prostate cancer, you can observe vigilantly and review the indicators regularly. It can be treated with traditional Chinese medicine. 2. In patients who are definitely diagnosed with prostate cancer, radical prostatectomy can be performed as long as the systemic condition allows. The treatment can be done by Chinese medicine. 3.Patients who are definitely diagnosed with prostate cancer and whose systemic conditions do not allow radical surgery or those who have metastasis can undergo debulking surgery or chemical debulking treatment. 4. Regardless of surgery or non-surgery, patients should be treated with traditional Chinese medicine. It can fight against tumor and metastasis, improve immunity, enhance quality of life and prolong survival rate. Preventive note 1.Living a regular life, combining work and rest, biological clock is not disrupted. 2.Reasonable and appropriate sexual life, no indulgence, no abstinence, as much as possible and in a happy mood. 3, more exercise, the appropriate way of exercise within the means, it is important to adhere to. 4, eat more tomatoes, grapes, onions or lycopene, etc.; do not eat spicy, do not smoke, do not drink alcohol, do not drink carbonated drinks, do not drink coffee. 5.People with family history of tumor should go to the hospital regularly for consultation or periodic review of comparative indicators.
