This is a huge disease that is killing people all over the world. The field of cancer study is called Oncology. The government has spent billions of dollars on research of this fatal disease.

Carcinogens are generally classified into three groups- chemical, biological, and physical. Chemicals that cause cancer have many different molecular structures and can be just about any type of c hemical. Some substances that cause cancer are complex chemicals and gases, certain metals, drugs, hormones, substances in molds and plants and many more. Many nitrosamines, or simple organic oxides of nitrogen, are carcinogenic. That and hydrocarbons are carcinogens in cigarette smoke and increase the risk of lung cancer. Also another chemical gas, vinyl chloride, gas has been found to be an agent of sarcoma of the blood vessels in the liver. Many drugs as well as alkylating agents used to treat cancer are carcinogenic. Even though these chemicals break the DNA of cancerous cells, which kills them, it also induces cancer in normal cells. Some hormones created in humans can also cause cancer. High levels of estrogen, which is marked as a female hormone, can increase the chances of getting a cancer of the uterus (in women). Aflatoxin B is a substance produced by the mold Aspergillus that causes a number of cancer, but generally liver cancer. Many carcinogens have not been discovered but research is being done to discover other carcinogens to keep people aware and safe. There are also many different biological agents which cause cancers.
