What kind of pollution increases the risk of lung cancer

September 08, 2023

1 risk of lung cancer.


Survey data from 2004 indicate that an estimated nearly 2 million people die prematurely each year as a result of indoor air pollution caused by the use of solid fuels. Of these deaths, 44 per cent died of pneumonia, 54 per cent of chronic obstructive pulmonary disease (COPD) and 2 per cent of lung cancer. About 1.5% of lung cancer deaths each year are caused by exposure to indoor air pollution carcinogens, and women are twice as likely to develop lung cancer as those who are not exposed. In addition, there is evidence that indoor air pollution is also associated with low birth weight, tuberculosis, ischemic heart disease, nasopharyngeal and laryngeal cancer. At present, some known carcinogens that pollute the atmosphere include some aromatic vertical compounds, fat soldering compounds and other oxides and arsenic, nickel, plating, chromium, asbestos, etc., and more than 30 kinds of agricultural pesticides, herbicides and some radioactive substances.

2 carcinogens that contaminate food.

Carcinogens that pollute water sources include carcinogens in waste water discharged from various industries and transportation vehicles, such as chromium, cadmium, nickel, arsenic, phenol, tar, petroleum and their products, as well as organochlorine pesticides, nitrosamines and radioactive substances. Carcinogens in contaminated soil include inorganic cadmium, arsenic, some pesticides, chemical fertilizers and scattered materials after nuclear explosion. Among these carcinogenic factors that pollute the environment, the carcinogens in the atmosphere mainly enter the body through the respiratory tract, and their relationship with human bronchogenic carcinoma is relatively clear; water and soil pollution carcinogens generally affect the human body through soil "crops". Or soil, surface, groundwater and other links have an impact on people, among which carcinogens that pollute food are the most important. In recent years, with the continuous enhancement of urban residents' awareness of environmental protection and the strengthening of urban environmental protection law enforcement, a large number of industrial factories have been transferred to rural areas, resulting in the spread of urban-centered environmental pollution to rural areas and serious damage to the rural ecological environment.

3 the second most important cause of lung cancer after smoking.

These factories and mines mainly include chemical plants, printing and dyeing factories, paper mills, pharmaceutical factories, tanneries, alcohol factories, power plants, lime kilns and so on, among which the environmental pollution caused by chemical plants is the most common and serious. In order to help prevent cancer in developing countries, wHo requires governments to ensure that workplaces meet health and safety standards, stop using asbestos and benzene-containing organic solvents, ban smoking in the workplace, and provide protective clothing for open-air workers. In many countries, radon is the second most important cause of lung cancer after smoking. The rate of radon causing lung cancer is estimated to range from 3% to 14%. The high incidence of lung cancer among miners in Gejiu tin mine in Yunnan Province of China has been proved to be related to exposure to high levels of radioactive radon and its daughters in underground operations. Sino-US bilateral cooperative studies have also confirmed that long-term living in caves in northwest China, exposure to radioactive radon is also related to the incidence of lung cancer.

Patient evaluation

The 75-year-old patients with lung adenocarcinoma survived for 5 years after taking traditional Chinese medicine, and everything was good after CT examination.

After taking 40 doses of traditional Chinese medicine, the mass shrank in 58-year-old patients with pancreatic cancer.

Patients with endometrial cancer took only 10 doses of medicine, and the pain symptoms were relieved.

After treatment, the 72-year-old patients with cardiac cancer had cold legs, soft legs and stomach distension symptoms disappeared.
