Chen Yuxin also pointed out that the main cause of prostate cancer is still unknown, but there are 6 related high-risk groups, including:
- 1. Age: People over the age of 50 have a higher risk. In addition, the probability of occurrence will increase with age.
- 2. Genetic inheritance
- 3. Family history of disease: About 9 to 15% of prostate cancer patients have a family history of disease. The fathers, sons or siblings of men with prostate cancer also had a higher chance of getting prostate cancer than those with no relevant family history.
- 4. Race: African-Americans have the highest incidence, and Asians have a lower incidence.
- 5. High-fat diet: especially unsaturated fat, will increase the incidence and mortality of prostate cancer.
- 6. Inflammation and infection: It is mentioned in the literature that the development of prostate cancer is related to a history of sexually transmitted diseases or chronic inflammation of the prostate.
Improve eating habits and prevent cancer
Ye Weijin, a Hong Kong urologist, said that the increasing incidence of prostate cancer among Chinese people is not unrelated to Western food culture.

He believes that cancer prevention can be achieved by Start with a diet, including eating more antioxidant fruits and vegetables such as tomatoes. He cited the United States, Germany and the United Kingdom and other places, there are many phytotherapy proposed by experts, such as saw palmetto (Saw Palmetto), omega 3 (Omega 3) food, etc.; Chinese experts also proposed that green tea is also effective against cancer. However, Ye Weijin reiterated that in addition to diet, men are still advised to check their health every year and establish a healthy eating habit of eating more vegetables and less red meat.
Prostate Cancer Screening
According to information from the Department of Health, there are currently two types of prostate cancer screening tests, namely digital rectal examination and prostate-specific antigen blood test.
During a digital rectal exam, the doctor places a gloved finger into the patient’s rectum to determine if there is any abnormality in the prostate, which is close to the rectum.
The PSA blood test involves taking a blood sample from the patient to measure the PSA level in the blood. Prostate-specific antigen is made by the prostate and released into the blood. Several prostate abnormalities, such as prostatic hypertrophy (BPH), prostatitis, or prostate cancer, can increase PSA levels in the blood.
