Features: The onset of prostate cancer is hidden It is understood that prostate cancer is the most common malignant tumor among men in developed countries such as Europe and America, and the incidence of prostate cancer in the United States has now surpassed that of lung cancer. In China, prostate cancer used to be a relatively rare disease, but with the improvement of people’s standard of living and medical care, and the increasing life expectancy, prostate cancer is becoming more and more common. Epidemiological data show that the incidence of prostate cancer in China has increased from 1.71 per 100,000 male population in 1993 to 7.9 per 100,000 male population in 2005, and it is surging at a rate of 10% per year. In China’s urban men, the incidence of prostate cancer has ranked among the top ten of all malignant tumors. Professor Chen Zhiqiang, vice president and director of major surgery of Guangdong Provincial Hospital, said that the onset of prostate cancer is very insidious, once the symptoms appear, it is already found to be late in hospital examination, and about 60 to 70 percent of people have cancer metastasis, at which time the treatment becomes more difficult and the efficacy is not as ideal as early treatment. Professor Zhang Yaqiang, deputy director of the Department of Urology at Guang’anmen Hospital of the Chinese Academy of Traditional Chinese Medicine Sciences, suggests that men over the age of 50 should undergo a relevant annual medical checkup. If prostate cancer can be detected at an early stage and the appropriate treatment is taken in time, a good prognosis can be achieved. So, how to detect prostate cancer at an early stage? Professor Chen Zhiqiang said, through anal finger examination, experienced doctors can detect abnormalities, and with ultrasound examination, PSA (short for prostate-specific antigen) test and then biopsy can confirm the diagnosis of prostate cancer, but the simplest method at present is PSA test. The PSA is a protein secreted by the prostate gland and duct cells, and once you have prostate cancer, the PSA value will increase. It is best for men over 50 years old, especially those with lower urinary tract symptoms, to have their PSA tested annually. If an elderly man has symptoms such as frequent urination, difficulty urinating, hematuria, hematuria, and urge incontinence, he should seek medical attention as soon as possible so that the diagnosis can be confirmed and treated early. Professor Chen Zhiqiang told reporters that if prostate cancer is detected in time, it can achieve better results through standardized treatment. At present, advanced prostate cancer can be effectively controlled by luteinizing hormone releasing hormone analogues such as goserelin acetate and anti-androgen drugs such as bicalutamide tablets.
