What factors are related to the increase in the incidence of prostate cancer in China?

1. Possible reasons related to the increasing incidence rate include: the popularization of the concept of routine physical examinations; the continuous promotion of the concept of PSA screening for prostate cancer-related tumor markers; the improvement of diagnostic technology; and the impact of environmental changes and changes in eating habits on the incidence of tumors.

Second, the aging of the population also plays an important role in the increase in the incidence of prostate cancer. In recent years, the aging trend of China's population has become increasingly obvious. It is estimated that by 2040, the proportion of the elderly population aged 65 and above will exceed 20% of the total population. At the same time, the trend of the elderly population is becoming increasingly obvious: the number of elderly people aged 80 and above is increasing at a rate of 5% per year, and will increase to more than 74 million by 2040. As a disease that elderly men are prone to, it can be expected that the incidence of prostate cancer in China will continue to increase in the future.

3. The significant imbalance in the incidence rate between urban and rural areas and between different regions reflects the differences in the level of medical care in different regions, which may lead to differences in the understanding of the disease and the importance of early screening. On the other hand, it also suggests that living environment factors may play an important role in the development of prostate cancer. The evidence in this regard comes from two aspects:

1. Many studies have shown that compared with traditional Eastern eating habits such as vegetables, tofu, and tea, a Western diet high in sugar, fat, and caffeine is more likely to increase the incidence of tumors.

2. Research data show that the incidence of prostate cancer among Chinese people living in the United States is significantly higher than that among Chinese residents living in mainland China. This also shows that in addition to racial differences, the dietary environment is also an important factor closely related to the incidence of prostate cancer.
