Liver cancer is called poor people’s cancer, which may be related to the dietary habits, regional development and economic conditions of most of the affected people. The dietary conditions and habits of people in underdeveloped areas may be relatively poor, thus increasing the chance of developing the disease. However, the incidence of the disease is related to a number of factors, and all kinds of people are at risk of the disease: 1. Dietary habits: Some people in poor areas have the habit of eating overnight food, and food storage conditions are poor, and food stored for a long time and under poor storage conditions is prone to deterioration, which may produce aflatoxin, which will have toxic effects on the human body and become a precondition for liver cancer. In addition, in some poor areas, the chemical industry is more serious pollution, long-term drinking water sources are contaminated, or water purification measures are not in place, resulting in abnormal algae reproduction, will have an impact on water quality. Long-term drinking of polluted water containing a lot of toxic and harmful substances can damage human liver cells and easily induce liver cancer. 2. Regional development: In China, the main cause of liver cancer is viral hepatitis, and hepatitis, cirrhosis and liver cancer are called the trilogy of liver cancer patients. In regions with poor economic development, the degree of medical education is also relatively low, and the overall medical knowledge and literacy level of the population may be relatively low, so they do not understand the causes of liver cancer. They may not have timely treatment and protection after toxic hepatitis, and lack of awareness of relevant treatment and review after cirrhosis, resulting in continuous progress of the disease and eventually liver cancer. In addition, the vaccination rate in poorly developed areas may be low and the prevention of infectious liver diseases is not yet perfect, resulting in a relatively high incidence of liver cancer. 3. Economic conditions: People with poor economic conditions may not pay attention to early symptoms and refuse to spend money on physical examination when they are not diagnosed, resulting in missing the opportunity of early liver cancer treatment. As liver disease patients have long treatment cycles and large treatment expenses, families with poor economic conditions can hardly bear the huge financial burden, which leads to liver disease patients not being able to receive periodic and effective treatment, resulting in aggravation of the disease. In addition, heavy drinking habits and long-term exposure to chemicals such as vinyl chloride and nitrosamines are also important factors that induce liver cancer. The right way to prevent and treat liver cancer is to pay attention to good dietary habits, quit smoking and drinking, and seek medical treatment in time after discovering uncomfortable symptoms. Patients who have been diagnosed with liver cancer must take active treatment measures to improve the quality of life and prolong the survival period.
