What are the factors of prostate cancer

The causes of prostate cancer are very complex. Currently known high-risk factors include age, race, genetics, diet, vasectomy, smoking, obesity, and other prostate lesions.

Age: Elderly people are more likely to get sick

Prostate cancer mainly occurs in elderly men. A group in the United States reported that about 30% of autopsies of men over 50 years old had prostate cancer, and the rate reached 50% in those over 80 years old.

Genetics: Prostate cancer runs in families

Men with a family history of prostate cancer have a significantly increased risk of developing prostate cancer.

Dietary factors: High-calorie fatty foods are dangerous

Among the risk factors, the most preventive ones are the dietary factors that induce prostate cancer. Studies have shown that excessive intake of fatty foods will increase the incidence of prostate cancer, while a diet rich in soy protein will reduce its incidence. The incidence of prostate cancer among Chinese and Japanese immigrants in San Francisco, USA is 3-7 times that of native-born people. One of the important factors is that they eat more fatty foods than native-born people. Excessive intake of fat will lead to increased cholesterol synthesis, which will further lead to an increase in androgens synthesized based on cholesterol. An increase in the ratio of testosterone in androgens is an important factor in the development of prostate cancer. It is now believed that the ideal ratio of fat in the total calories of the diet is 10%-20%.

The lower incidence of prostate cancer in Asian countries is also related to the high intake of soy protein foods. This is because such foods are rich in phytoestrogens, whose chemical structure is similar to estrogen in the human body and have a certain inhibitory effect on androgens. Of course, there are far more dietary factors that induce prostate cancer. For example, catechins in green tea or vitamin E and selenium in fresh vegetables and fruits can inhibit the occurrence of prostate cancer.

There are five dietary measures to prevent prostate cancer: first, the proportion of fat in the total calories of food should be less than 20%; second, 20-40 grams of soy products should be consumed daily; third, 200 micrograms of selenium per day; fourth, 400-800 international units of vitamin E per day; and fifth, drinking more green tea. Items 3 and 4 can also be replaced by eating more fresh vegetables and fruits.

Others: Obesity, smoking, and surgery can increase the incidence of prostate cancer

Although a few studies suggest that people who undergo vasectomy have an increased risk of prostate cancer, most studies disagree. Other studies have shown that benign prostatic hyperplasia, excessive obesity, lack of exercise, smoking, radiation, or sexually transmitted viruses may increase the incidence of prostate cancer. Older men with relevant risk factors need to be vigilant, give up bad eating and living habits, and moderate exercise may be meaningful for the prevention of prostate cancer.
