Take a rural area in Shandong as an example. 10 years ago, there was only one cancer patient in a few years. Since 2005, there have been several cancer cases and deaths every year, most of them are middle-aged and elderly people aged 50-60, but there are almost no elderly people over 90. These deaths and the decrease of the elderly population will definitely lower the average age of the local population.
At present, it is not easy to reduce the risk of population death, because the economic development is still in a high-speed stage, the phenomenon of large-scale use of chemical fertilizers and pesticides is difficult to change in the short term, environmental pollution is temporarily out of control, and food and health risks will not be reduced; Coupled with the persistence of traffic accidents and violent crimes, the death risk of the population as a whole will remain high.
What we can do now is to strengthen the reform of the national medical system, increase the medical security of the rural population, and reduce the deaths of people who could have been prevented by treatment, but this can only be a remedial measure and it is difficult to fundamentally solve the problem.
