The incidence of prostate cancer has been increasing rapidly in recent years. With the advent of an aging society, prostate cancer should attract more public attention and men over 50 should undergo annual prostate cancer screening. The most important thing is that you should be aware of the fact that you have to be careful when you are going to be in the market. The symptoms such as difficulty in urination, increased night urination and incomplete urination may not be attributed to prostatitis and hyperplasia, but behind these symptoms, there may be prostate cancer. As one of the common malignant tumors in men, the incidence of prostate cancer has been increasing rapidly in recent years. In Guangzhou, for example, the incidence of the disease has doubled in the last decade. When the tumor grows, it can compress the urethra and cause symptoms similar to prostate enlargement such as frequent and urgent urination, straining to urinate, and excessive nocturia. In the late stages, patients may experience urinary retention or even complete inability to urinate. Some patients do not notice the abnormal urination at first, but they do not know that they have prostate cancer until they have bone pain or even pathological fracture, and then the tumor has metastasized to the pelvis and spine. The screening should be advanced to 45 years of age for those who have a family history of prostate cancer. The high risk group for prostate cancer includes those who have high prostate specific antigen (PSA) and pathological changes in the prostate. People who are over 50 years old and have a father or brother with prostate cancer also have a higher risk of developing the disease than the general population. Since prostate cancer is difficult to prevent, early detection becomes very important. Men over 50 should have a blood test for prostate-specific antigen (PSA) plus a rectal exam, and if possible, a prostate ultrasound. The most important thing is that it is a good idea to take a look at the actual results. The most important thing for men is that they should not be afraid to have a rectal exam. It is important to be aware that some prostate cancer patients do not have high PSA values, so to avoid missing out, you can add a prostate ultrasound if you are able to. The starting age of screening should be advanced to 45 years old for those with a family history of prostate cancer. If the first PSA test is low, a second test can be performed two to three years apart. If the first PSA test is high, further screening should be done according to medical advice and more frequently than in the general population.
