How to prevent prostate cancer

With the change of eating habits, the incidence of prostate cancer is getting higher and higher. So we all need to know something about the prevention of prostate cancer. So what is the prevention knowledge of prostate cancer? Let's learn about it together.

1. The currently generally accepted effective method for screening is rectal examination plus serum PSA concentration measurement.

Serum PSA levels are used to test male citizens over 40 to 45 years old, and follow-up measurements are performed once a year. This screening method is cost-effective. If PSA exceeds 4.0 ng/ml, a rectal digital examination or ultrasound examination is performed. If positive or suspicious, a needle biopsy is performed. This method can effectively detect early localized prostate cancer. Generally speaking, an increase in free PSA is seen in benign prostate hyperplasia, while free PSA decreases in prostate cancer patients. Therefore, if the free PSA is >25%, the patient is likely to have no prostate cancer (less than 10% probability), and if it is <10%, the patient is likely to have prostate cancer (60% to 80% probability), and it is very meaningful to do a prostate biopsy at this time.

2. Avoiding risk factors is difficult to do. Because there are many clear risk factors, heredity, age, etc. are unavoidable, but potential environmental risk factors such as high-fat diet, cadmium, herbicides and other undetermined factors may be avoided. It is now known that about 60% of the factors causing prostate cancer come from the living environment. Occupations with statistically significant risks are agriculture, related industrial soap and perfume and leather industries, so farmers, leather workers and management staff in these industries have a significant increase in incidence. In addition, people who are exposed to chemicals, herbicides, and fertilizers have an increased risk of prostate cancer. According to new reports, fish oil containing antioxidants in food can protect and reduce the risk of prostate cancer. The magnesium content in drinking water can prevent prostate cancer. In addition, measures such as adhering to a low-fat diet, eating more soy foods rich in plant protein, drinking Chinese green tea for a long time, and appropriately increasing the content of trace elements selenium and vitamin E in the diet can also prevent the occurrence of prostate cancer.

3. Chemoprevention According to the drug's interference method, chemoprevention can be divided into the following main categories, such as tumorigenesis inhibitors, anti-tumor growth drugs, and tumor progression inhibitors. Since the occurrence and development of prostate cancer is a long process, we can use drugs to chemoprevent or inhibit the occurrence and development of prostate cancer. It may inhibit the growth-promoting effect of testosterone on prostate cancer cells. This effect is still under clinical research observation and needs to be confirmed. Other drugs such as retinal have the effects of promoting cell differentiation and anti-tumor progression. They are also under clinical research and may become potential chemoprevention drugs.

The above is an introduction to the prevention of prostate cancer. I hope it will be helpful to everyone. If you find any abnormal symptoms, please go to the hospital in time. If you still have questions, please consult our online doctor and we will give you a detailed answer. Feihua Health Network wishes you good health!
