Types
We are around carcinogens every day, whether at work, at home, or at play. Carcinogens do not cause cancer in everyone who is exposed; the ability of a carcinogen to cause cancer depends on many factors, including the amount of exposure, the length of exposure, the health of the individual, and other factors in the person's life that either raise or lower the risk of cancer.
People also differ in personal susceptibility to a carcinogen based on their genetic makeup. In many cases cancer is multifactorial, meaning that there are several factors that work together to either cause or prevent cancer. Types of carcinogens include:
Chemicals/substances - Certain chemicals used the home or workplace may be carcinogenic. For example, asbestos in insulation can lead to lung cancer and mesothelioma. Many people have a sense that if a chemical could cause cancer it would not be allowed in our homes. That's not the case.
Environmental radiation – Ultraviolet radiation from the sun is a well-known cause of skin cancer. Radon emitted from the normal decay of uranium in the soil and then trapped in homes is a leading cause of lung cancer.
Medical radiation - Both radiation used medically for diagnostic tests and that used to treat cancer are considered carcinogens. For example, women who receive radiation therapy after a mastectomy for breast cancer are at an increased risk of developing lung cancer due to the carcinogenicity of radiation.
Viruses - Viruses such as human papillomaviruses which cause oral cancerand cervical cancer, and hepatitis C which can cause liver cancer are considered carcinogens. Check out the other viruses which are thought to cause cancer.
Some medications - Some chemotherapy drugs and hormonal therapy can raise the risk of cancer. For example, chemotherapy used to treat women with early stage breast cancer may sometimes lead to leukemia. Oral contraceptive use may increase the risk of breast cancer in young women.
Lifestyle factors – Smoking and obesity are both carcinogens in that they can be responsible for the mutations which result in cancer
