1, male cancer prevention misunderstanding
1, squatting to urinate can reduce the risk of bladder cancer?
Wrong!
First of all, there is absolutely no need for men to squat and urinate. Because, for most men, the contractility of normal bladder detrusor can completely empty urine in the bladder. Only some patients with moderate or severe prostatic hyperplasia or bladder detrusor weakness need to use abdominal pressure to help urinate. If the abdominal pressure is not enough to empty the urine in the bladder when standing, it is meaningful to urinate in a squatting position.
However, if the patient's micturition symptoms have reached such a serious level, further treatment measures are often needed, such as drug therapy or surgical treatment of benign prostatic hyperplasia and indwelling catheter. Therefore, men squatting to urinate can not reduce the risk of bladder cancer.
2, urinating once an hour can reduce bladder lesions?
Wrong!
Normal adults urinate 4~6 times during the day and O~2 times at night. In clinical work, urinating once an hour can be considered as frequent urination. Especially at night, getting up and urinating once an hour greatly affects the quality of sleep and the life and work of the next day, which is not worth the candle.
Bladder is the most common part of urinary system tumor, and the long-term stimulation of urine to bladder mucosa is one of the causes of bladder cancer. However, there is an idealized model that urination every hour can reduce the risk of bladder lesions, which has not been confirmed by clinical research, and it is difficult to obtain practical application and effect.
3, sitting down immediately after urinating is easy to cause prostatitis?
Wrong!
This view has no theoretical basis. After male urinates, the internal and external sphincter of urethra will close, making the urethra of prostate form a closed cavity. If you sit down immediately at this time, the pressure in this closed cavity will not increase. In addition, the internal urethral sphincter is also a part of the bladder neck. This part of the muscle has little closing force, and the residual urine will only flow back to the bladder, not into the prostate, and will not cause prostatitis. Only when men hold their urine for a long time or stop urinating suddenly, urine will flow back into the prostate due to the increase of pressure in the prostate urethra, which will lead to prostatitis.
4. Squeezing perineum after urinating can reduce the risk of prostatitis?
Wrong!
After urination, the urine discharged by squeezing perineum is not the residual urine in the bladder, but the urine in the bulbar urethra. The bulbous urethra and penile urethra are called anterior urethra, membranous urethra and prostatic urethra are called posterior urethra, and the distal end of prostatic urethra has external urethral sphincter. After urination, the external urethral sphincter is closed. Therefore, after urination, the residual urine in the bulbous urethra cannot reach the prostatic urethra, and of course it will not cause prostatitis. Its function is only to prevent urine from flowing out of wet underwear. Doing more levator ani exercises at ordinary times can enhance the contractility of perineal muscles and urethral muscles. However, levator ani exercise is mainly to exercise the urethral sphincter, which can help some patients with urinary incontinence to control urine, but it can't help to empty the residual urine in the bladder. Therefore, squeezing perineum after urinating and doing more anal exercise can not reduce the risk of prostatitis. And squeezing perineum after urinating is also a difficult project for ordinary men.
2. Methods of preventing male prostate cancer
1, check regularly
Men's health examination, especially elderly men, should pay special attention to the examination of prostate, and carry out detailed examination by scientific means to facilitate early detection.
2. Eat enough selenium-containing food.
Studies have shown that the risk of prostate cancer in men with high blood selenium concentration will be reduced by 4-5 times, and the organic selenium in green vegetables is more conducive to human absorption, so men can eat more green vegetables, such as Chinese cabbage and cauliflower with tender stems.
Step 3 eat more soy products
Soybean contains an antioxidant called trihydroxyisoflavone, which has a strong anti-cancer effect, so it is best to eat more soy products.
4. Proper application of sex hormones
The occurrence of prostate cancer is closely related to sex hormones. If the secretion of sex hormones in men is insufficient, appropriate sex hormones can be used under the guidance of doctors, but they should not be used on their own or excessively, especially elderly men, who are at high risk of prostate cancer. Once prostate cancer is in the incubation period, the consequences of using sex hormones will be more serious, so men should not use sex hormones themselves, let alone take androgen aphrodisiacs sold in the market.
