What are the causes of prostate cancer

Prostate cancer refers to an epithelial malignant tumor that occurs in the prostate gland. The incidence rate increases with age. Male friends should pay more attention to it, learn more about the causes of the disease, take preventive measures, and reduce the incidence rate. Let's learn about the pathogenic factors of prostate cancer.

1. Age: The incidence of prostate cancer is positively correlated with age. 95% of prostate cancer patients are aged between 45 and 90, with an average age of 70. From 50 to 85 years old, the incidence rate increases by 21% to 65% for every 5-year increase in age. Prostate cancer is becoming younger.

2. Sexual activity: Those who start sexual activity early and frequently during puberty have a greater risk of developing prostate cancer, and the later they lose their sexual ability, the greater the risk. Masturbation is also related to prostate cancer. In addition, those who have sexually transmitted diseases or too many sexual partners have a higher risk of developing prostate cancer.

3. Chemistry: Prostate cancer is related to cadmium. Cadmium is a common heavy metal in industrial pollution. The main causes of prostate cancer are smoking and occupational exposure. People who have been engaged in chemical, dye, rubber and printing occupations for a long time have a greater chance of being exposed to cadmium and are at greater risk of developing prostate cancer.

4. Nutrition: A high-fat diet is a risk factor for prostate cancer, especially red meat. Linoleic acid is often associated with prostate cancer, while fat from fish and dairy products has less impact. There is a dose-response relationship between prostate cancer and total fat, carotene, selenium, saturated fatty acids, and animal fat intake. Retinol, in particular, can increase the incidence of prostate cancer.
