Explain the causes of prostate cancer

Understanding the causes of prostate cancer is crucial to the prevention and treatment of this common and dangerous cancer. As a type of cancer, prostate cancer has many causes and different levels of danger. Below, experts will explain the causes of prostate cancer in detail.

1. Absolute risk factors:

(1) Age: Prostate cancer patients are mainly elderly men. The median age of newly diagnosed patients is 72 years old, and the peak age is 75-79 years old. In the United States, more than 70% of prostate cancer patients are over 65 years old. Therefore, age is an extremely important factor in the etiology of prostate cancer.

(2) Family history: If a direct relative has prostate cancer, the risk of the patient developing prostate cancer will double. If two or more direct relatives have prostate cancer, the relative risk will increase to 5 to 11 times. Epidemiological studies have found that patients with a positive family history of prostate cancer are diagnosed about 6 to 7 years earlier than those without a family history.

(3) Race: Although the incidence of prostate cancer in Asians has not yet reached the level of European and American countries, the incidence of prostate cancer has shown an increasing trend year by year. The cause of this prostate cancer is also related to the genetic factors mentioned above.

2. Relative risk factors:

The exact cause of these prostate cancers is still under discussion, but a diet high in animal fat is an important risk factor. Other risk factors include low intake of vitamin E, selenium, lignans, and isoflavones. Sunlight exposure is inversely correlated with prostate cancer incidence, and sunlight increases vitamin D levels, which may be a protective factor for prostate cancer. In Asia, where prostate cancer is less common, green tea consumption is relatively high, and green tea may be a preventive factor for prostate cancer.

The cause of prostate cancer is still unclear in medicine. The above is the conclusion drawn from many years of clinical experience. The cause of prostate cancer varies depending on personal life and work environment. You can consult our online experts to learn more about the cause of prostate cancer.
