In order to take a good prevention from liver cancer and reduce the occurrence, people have contributed to finding out the causes for long. According to scientific and research data, it is thought to be the following 7 chief risk factors resulting in liver cancer.
1. Pollution of waterhead
The severe pollution of drinking water is one of the primary inducements. The chance for polluted waterheads to cause liver cancer ranges from high to low are ditch-water, river water and well water. So the villages without water supplement should have well water.
2. Viral hepatitis
The viral infection of hepatitis B and C. Especially the carriers and patients of hepatitis B, the chance for them to develop primary liver cancer is 2-10 times higher than common people. In the districts of high incidence of liver cancer, the patients or virus carriers of hepatitis B take up to 20%.
3. Aflatoxin
Aflatoxin B is a kind of important cancer-causing agent that grows in the hot and humid environment. It widely exits in the mould food, grains and fodder being polluted. If people take those polluted food for long would develop liver cancer.
4. Chemical cancer-causing agents
Nitroso-compound is the main chemical materials leading to cancer, such as nitrosamine, nitrosamide and so on. Apart from that, pesticide, alcohol and safrole can induce liver cancer too.
5. Gene mutation
Some people think the mutagens and viruses in environment stimulate the activity of reaction path in liver cell division to cause point mutation and group translocation. Those can be the possible factors accelerating the growth of cancer cells.
6. Immune state
When some other also accepted that, in the blood plasma of liver cancer patients, there is a kind of blocking factor which can inhibit the immunity of cells and protect liver cancer cells from being killed by immune cells. Researches also have proved that α-fetoprotein can inhibit the phagolysis of lymph cells and macrophage.
7. Other risk factors
Excessive or deficient nutrition (such as lack of vitamin A or B1), hematochromatosis, parasitic infection and heredity can also cause liver cancer.
*Surgery, in addition to the appropriate chemotherapy and radiotherapy, are effective in treating early cancer, but certain patients in late stage of cancer may not be tolerate surgery well as they can be relatively weak. A combination of carefully planned minimally invasive therapy, chemotherapy or radiotherapy can effectively reduce the side effects and discomfort of treatment and may help patient get better efficacy.
