Pay attention to the screening of prostate cancer PSA to protect men's health!

Prostate cancer is one of the common malignant tumors in male urogenital systems. Early symptoms are hidden and easily ignored, resulting in the best time to miss the best treatment. Early screening, discovery and diagnosis of prostate cancer are extremely important for patients' treatment and prognosis. Poor living habits such as high -animal fat foods, obesity, sedentary exercise habits such as high -animal fat foods are often eaten to increase the risk of prostate cancer. Professor Huang Jian, the chairman of the Chinese Medical Association's Urology Science Branch, and the director of the Department of Urology, Sun Yixian Memorial Hospital of Sun Yat -sen University, suggested: "Middle -aged and elderly men should pay attention to preventing prostate cancer and regularly conducting prostate special -specific antigen (PSA) to protect their own health. "

Prostate cancer becomes the largest male in the world

Urinary tumors, early screening is important

The incidence of prostate cancer ranks first among the global male urinary tumors, and the incidence of prostate cancer in my country has increased year by year. Compared with European and American countries, prostate cancer diagnosis is late and the survival period is not ideal. Taking the United States as an example, nearly 91%of patients with prostate cancer were found in the early stage, and the prognosis effect was better after receiving standard treatment, and the 5 -year survival rate was nearly 100%. In the first diagnosis of more than 2/3 patients in my country, it was a late or local period. The best treatment time was missed, and the prognosis was poor. 1

Prostate cancer is generally asymptomatic early. With the development of tumors, symptoms such as difficulty in urination, frequent urination, urgency, dysuria, urination, urinary retention and other symptoms are similar to the symptoms of prostate hyperplasia. 2 In the United States, 90 % of prostate cancer was found through screening, and the early screening awareness of prostate cancer in Chinese people was weak, and the awareness rate of PSA screening was low. Professor Huang Jian introduced: "In our country, prostate screening is far from sufficient, leading to the high mortality of prostate cancer in my country. At present, screening is the only effective means of early discovery of prostate cancer."

High -risk population once a year PSA screening is essential

There are two main methods of prostate cancer screening: one is the rectal test; the other is PSA screening. Relatively speaking, the degree of pain and shame of rectal fingers is strong, and many people avoid taboos. The PSA screening only needs to be drawn with blood, which is more convenient and less painful. Popularity of PSA screening helps early detection of prostate cancer, treatment as soon as possible, extend life, and improve the quality of life. Therefore, high -risk population is recommended to conduct regular serum PSA screening. If necessary, you can further do the B -ultrasound of the prostate cancer. If there are obvious abnormalities, you can do a clear diagnosis of puncture biopsy.

PSA is a lingedine protease secreted by prostate blisters and ductal epithelial cells, which directly secretes to the prostate duct system. If it is affected by tumors, hyperplasia and inflammation, the normal glandular duct structure will be destroyed, and the serum PSA concentration will different. The degree increase. Prostate inflammation, prostate hyperplasia, acute urinary retention, prostate massage, prostate puncture biopsy, etc. will increase PSA, but after symptomatic treatment such as anti -inflammatory and anti -prostate hyperplasia, PSA can tend to be normal.

Professor Huang Jian further introduced: "The Consensus of the Society of Chinese Prostate Cancer Screening recommends that men do PSA screening once a year after the age of 50. 3. Serum PSA & 4.0 μg/L (micro gram/liter) is the critical value of the PSA screening indicator.

In addition, Professor Huang Jian also introduced the method of preventing prostate cancer -pay attention to reasonable diet, try to eat low -fat diet, eat more vegetables and fruits; Lifetime.
