The incidence of prostate cancer varies around the prostate cancer prevention area

Warren Buffett, the shareholder of his company, Berkshire Hathaway, sent a letter saying that he had been diagnosed with prostate cancer, but he was still optimistic in the letter that he was feeling well now, and the doctor said that his disease was "not life-threatening at the moment."What causes prostate cancer?

The incidence of prostate cancer varies from place to place

Prostate cancer is a malignant tumor that originates from the prostate. If a gene mutation in one of the cells causes uncontrolled proliferation, it becomes cancer. In addition to enlargement or invasion of adjacent organs, malignant cells may also metastasize to other parts of the body, especially bones and lymph nodes. Prostate cancer can cause symptoms such as pain, difficulty urinating, and erectile insufficiency.

Prostate cancer occurs all over the world. Incidence varies from place to place. The incidence is highest in the world in the United States, followed by Europe (which varies across Europe) and lowest in East and South Asia. In terms of ethnicity, black people have the highest incidence of prostate cancer, and white and yellow people have the lowest incidence of prostate cancer. The incidence is lower in native yellow people than in those who move to North America. However, in recent years, the incidence rate in our country has been on the rise. Prostate cancer is the second most common cancer in men, second only to lung cancer in the number of people who kill them.

What causes prostate cancer?

(1) Age: Age is the main risk factor for prostate cancer. Prostate cancer is very rare in men younger than 45 years of age, but the incidence of prostate cancer increases dramatically with increasing age, and the vast majority of prostate cancer patients are older than 65 years old. Basically, the incidence of prostate cancer almost doubles for every 10 years of age after the age of 40, and the risk of prostate cancer in men aged 50~59 is 10%, while the risk of prostate cancer in men aged 80~89 years increases sharply to 70%.

(2) Family history: When there is an immediate male relative in the family who suffers from prostate cancer, the incidence of male cancer in the family is significantly higher. Immediate male relatives generally refer to fathers and brothers. If one of the relatives has prostate cancer, the probability of developing prostate cancer is 1 times higher than that of the general population; If there are 2, it will be 3 times higher. This suggests that the development of prostate cancer may be related to one or a group of genes in the body, although these genes have not yet been fully identified by scientists.

(3) Ethnicity: Prostate cancer has the highest incidence among African Americans (i.e., Black Americans), followed by Hispanics and Caucasian Americans, while the incidence of prostate cancer in Black Africans is the lowest in the world. The incidence of prostate cancer in Asian men living in the United States is lower than in Caucasians, but significantly higher than in native Asian men. Although the incidence of prostate cancer in yellow people has not yet reached the level of European and American countries, whether it is Chinese mainland, Taiwan, Hong Kong, Japan, South Korea, Singapore, the incidence of prostate cancer is increasing year by year.

(4) Pathological changes with abnormal cells in the prostate: the incidence of prostate cancer is significantly higher in men with high-grade intraepithelial neoplasia of the prostate. High-grade intraepithelial neoplasia is a precancerous lesion that shows abnormal cell growth morphology under the microscope, although it is not cancerous, but often indicates the presence of prostate cancer, but it has not yet been detected.

How to prevent prostate cancer?

1. Studies have shown that the increased risk of prostate cancer is related to sexually transmitted diseases, especially gonorrhea.Genital wartsWait. Although the pathogenesis of prostate cancer has not been well understood, and it is generally thought to be related to the imbalance of sex hormone regulation, some inflammation has recently been suggested to be associated with prostate cancer.

2. Eat less spicy and irritating food, eat more light and easily digestible food, eat more fresh vegetables, prohibit smoking and alcohol, and keep the stool smooth.

3. Eat more protein-rich soy products, which can significantly reduce the incidence of prostate cancer. The ratio of fat to total calories in the diet is ideally 10%-20%.

4. Avoid compression of the prostate, do not sit for a long time, take appropriate rest and change the position in time to avoid local congestion of the prostate.

5. Regular life, regular daily life, and a certain amount of each meal, which has a protective effect on the prostate. Drink plenty of fluids and urinate more often, and frequent flushing of the urethra through urine can help prostate secretions pass to prevent infection.

6. Usually drink more water and urinate more, urination has the effect of flushing the urethra, which can help the prostate discharge excessive secretions and prevent prostate infection.

7. Keep a good mood and pay attention to personal hygiene. It's important to get enough sleep, have moderated sex and have an optimistic mindset, stick to hot baths, and try not to wear jeans or pants that are too tight.

8. Proper physical exercise can enhance the body's immunity and disease resistance.Regular exercise of the abdomen, thighs and buttocks can massage the prostate, improve blood circulation and lymphatic circulation, help strengthen internal resistance and reduce the incidence of prostate cancer.

9. Tobacco is another important risk factor for prostate cancer. Medical staff should first set an example of non-smoking, advise them to quit smoking, and reduce the harm of tobacco to the human body.
