What is the link between chemicals and cancer?
Cancer, which is uncontrolled cell growth that has harmful effects on organs and other body tissues, can be associated with the exposure of certain chemicals in the environment. Cancer cells become harmful when they multiply to a point where neighboring tissue attacks and eventually spreads to other body systems. Growth outside cell control is often initiated by repeated exposure to toxic chemicals, also called carcinogen. Chemicals and cancer incidence go hand in hand. Most of the research of the etiology of cancer focuses on a specific environmental cause, such as a chemical exposure to the workplace or exposure due to a lifestyle selection, for example.
The connection between chemicals and cancer begins when chemical carcinogen initiates a change within deoxy-ribonucleic acid (DNA), a process called initiation. Under normal circumstances, the defense of the body can identify the system and overAvap damaged parts of the DNA, but if the cell begins to reproduce, while the damage is still present in the genetic code and results in an abnormal cell with cancer potential. The only or several cases of the initiation process are usually not enough to develop cancer; Other factors, usually called "promoters", are often seen which seem to be present when uncontrollable growth occurs. These promoters include factors such as the initial chemicals in large quantities for a long time, nutritional deficiency or genetic predisposition to cancer. The connection between chemicals and cancer is not fully understood, but most scientists agree that one of these promoters is usually present in the development of cancer.
Research of chemicals and cancer has been carried out for decades; Perhaps the most famous studies of industrial and tobacco smoke as a potential carcinogen began in the United States in 1930 years. Over the course of decades they were in industrial and cigaretteDozens of chemicals causing cancer, such as benzopyrene and formaldehyde, found. Another example of the common chemicals concerning is the polyvinyl chloride produced in the production of PVC pipes. Its presence in many applications used by populations makes it one of the many chemicals that scientists continue to explore to understand their specific carcinogenic mechanisms. Research of chemicals and cancer refers to the use of certain chemicals to treat cancer when it occurs, which is called chemotherapy.
Relationships between chemicals and cancer cause and effect can be observed in benzene and leukemia, asbestos and lung cancer and vinyl chloride and liver cancer. The risk of cancer becomes significantly higher when they encounter carcinogenic chemicals. An example of this concept can be seen in factory workers who are exposed to toxic smoke in the workplace every day; Workers who smoked this exhibition have a 50% higher chance of developing lung cancer.
