Leukemia, commonly known as “blood cancer”, is a malignant tumor of the hematopoietic system, with an incidence of about 3-4/100,000 people in China, with acute patients accounting for more than 70%, and children under 13 years of age are the most prevalent group of leukemia. The incidence of all types of leukemia is higher in men than in women after the age of 50, and in recent years, the mortality rate of leukemia ranks 6th in a sample survey of domestic malignant tumors, while children rank 1st.
At present, it is believed that leukemia is not caused by a single factor, but is the result of multiple factors acting together on the organism.
I. Leukemia susceptibility factors The causes of leukemia are not yet fully understood, but research data indicate that its onset is closely related to viral infections, genetic, physical and chemical factors.
1, viral infection: human leukemia only adult T-cell leukemia (ATL) is definitely caused by a virus, other types of leukemia other than ATL have not been confirmed to be infectious.
2, genetic factors: leukemia patients do not pass the disease directly to their offspring, but leukemia is aggregated in some families, and the incidence of acute lymphoblastic leukemia is 30 times higher than expected in populations with consanguineous marriages. Most patients with acute leukemia have been found to have chromosomal abnormalities through current technology.
3, physical factors: physical factors associated with leukemia, mainly radiation.
4, chemical factors: benzene and certain drugs such as methylbenzylhydrazine, Maryland, Marfan, etc. are closely related to leukemia and can cause leukemia experimentally and increase the chance of concurrent leukemia when used to treat other human tumors.
Which groups of people are susceptible to leukemia and how to minimize the possibility of developing it? Current research on the etiology of leukemia shows that whether leukemia occurs in a given individual may depend on the interaction of multiple factors, including internal and external causes. According to research, the incidence of leukemia is likely to be higher in people with the following conditions than in the general population, the so-called “high-risk group”.
1. Children born from consanguineous marriages Children born from consanguineous marriages have a higher chance of developing the disease. The incidence of hereditary diseases in the offspring of consanguineous marriages is 150 times higher than in the offspring of non-consanguineous marriages, and these patients have high-risk genetic factors.
2. People with a history of exposure to chemicals and poisons Living near oil fields and chemical plants, or people with long-term exposure to chemical agents A young worker working in a shoe factory in Wenzhou was diagnosed with leukemia. The owner of the shoe factory never provided effective labor protection measures when the workers were working in order to pursue high economic benefits, which caused the blood disease over time.
Drivers with long-term contact with gasoline Blood diseases are relatively high among automobile drivers, that is because they have long-term contact with gasoline, which contains benzene. Therefore, in order to reduce human diseases, should minimize the leakage of gasoline, if driving can often smell the strong smell of gasoline, that is very dangerous. In addition, people who have been driving for a long time may want to go to the hospital for blood tests, if the previous blood test is normal, after driving, there is a significant drop in white blood cells, and not due to viral infections or other reasons, it means that very sensitive to benzene, should be very careful.
People with long-term exposure to hair dyes It is often found in clinical practice that patients suffering from leukemia can trace out a history of long-term hair dyeing. Therefore, people should prevent harmful hair coloring materials from being absorbed into the body while pursuing beautiful and fashionable hair coloring, especially children, the elderly and pregnant women should pay more attention to reduce the use or not to use hair coloring materials. Although there are no clear statistics, but according to the survey, black hair dye contains far more harmful ingredients than other color hair dye, so try to use less.
The main ingredient of many “ancestral recipes” for the treatment of psoriasis and rheumatoid arthritis is ethyleneimine, ethylene-bis-morin, etc., which is the culprit of leukemia, and has long been listed as a prohibited drug. Many patients take the “secret recipe” many times in an unknown state, and as a result, the psoriasis is cured, but suffer from leukemia.
People who inhale a lot of decoration pollution gas According to the test, most of the materials used for decoration such as density board, plywood, particle board, laminate flooring, core board and various emulsion paints and new furniture contain chemical synthetic substances, which can gradually release toxic gases such as formaldehyde, benzene, ammonia and radon. And people living in the indoor environment or car environment of the decoration pollution for a long time will easily induce blood diseases. Therefore, while pursuing luxury and comfort in interior decoration, we should also pay attention to environmental protection, use green and benzene-free paints, and let the room be fully ventilated for 1-2 months before moving in after the decoration is completed. Special attention should also be paid to the renovation of motor vehicles, to open the windows for a long time, after evaporating all the harmful gases before use.
3, had some special needs or accidents and radiation exposure to some tumors or other diseases patients may also induce leukemia after treatment such as X-rays or Y-rays irradiation. Some of the victims of radiation accidents develop various blood disease symptoms after a latent period of several years.
4, long-term heavy smoking and depressed mood of the crowd long-term heavy smoking has absolute harm to the body, will affect the body’s indicators, the general middle-aged and elderly male patients are long-term smoking “smokers”. Not only that, long-term active or passive smoking can cause other diseases. Long-term depression and other psychological disorders are also the culprits of blood diseases.
In short, as long as people try to stay away from the environment where leukemia is likely to occur, eat a reasonable diet, and maintain an optimistic and healthy mindset, they can minimize the chances of developing the disease and have a good quality of life.
