The review recalls the types of carcinogenic chemicals that are used in laboratories, as well as the types of cigarettes and nicotine for smokers, which are considered essential substances for cancer. Smokers are more likely to develop lung cancer, although lung cancer can also affect people who have never smoked. The risk of lung cancer increases with the length of time you smoke and the number of cigarettes you smoke. If you quit smoking, even after smoking for many years, you can significantly reduce your chances of developing lung cancer. Inhalation of carcinogenic lab materials or smoking causes lung cancer by damaging the cells lining the lungs. When you inhale cigarette smoke that is full of cancer-causing substances (carcinogens), changes in lung tissue begin almost immediately. At first, your body may be able to repair this damage. But with each repeated exposure, the normal cells that line your lungs are increasingly damaged. Over time, the damage causes cells to function abnormally and cancer may eventually develops. Many laboratories carry specific risks, including the risk of exposure to carcinogens, and preventing accidents in the laboratory requires high care and constant vigilance. Examples of risk factors include high voltages, pressures, high and low temperatures, corrosive and toxic chemicals, chemical fumes, radiation, fire and explosions, as well as biological hazards including infectious organisms and their toxins.
