In recent years, many patients with prostate cancer have been admitted to outpatient clinics and wards, and we found that patients generally do not know much about this disease, and because it is “cancerous”, patients and their families are somewhat frightened. Prostate cancer occurs mostly in older men and is becoming more and more prevalent. In the United States, prostate cancer has been the most common visceral malignancy in American men since 1984. The most important thing is that it is the most common type of cancer in the world. The incidence of prostate cancer is getting higher and higher with the improvement of China’s economic level and the application of PSA test, and it is gradually approaching to Europe and the United States, and it has a tendency to overtake the traditional cancer dominators such as lung cancer and stomach cancer. Let’s do a simple mathematical calculation, in my city of Beijing, for example, for every 10,000 men, there are 2 new cases of prostate cancer each year, and according to the 2010 census, for example, the population over 60 years of age accounts for 20% of the total population, considering that prostate cancer hardly occurs in men under 50 years of age, that means that for every 2,000 older men, there are 2 new cases of prostate cancer each year, and this is only This is only the number of new cases each year, and counting patients who already have prostate cancer, prostate cancer can be considered extremely broad in coverage. For those of you who have been to the hospital for prostate related diseases, you know what tests are done for prostate cancer: blood test for PSA, prostate palpation by the doctor with his finger in the anus, ultrasound of the prostate by holding urine, and prostate MRI. Based on the results of these tests, we will select some patients for prostate puncture, and if the pathology of the puncture shows cancer, we will selectively give the appropriate treatment according to the patient’s different conditions: active monitoring (so-called regular review), surgery, radiotherapy, and endocrine therapy (so-called conservative therapy with injections and medication). The above paragraph almost summarizes the set of diagnosis and treatment process of prostate cancer in our usual work.
