Which of the following is cancer causing agent?
X-radiation and gamma-radiation are listed in the report as “known human carcinogens” because human studies show that exposure to these kinds of radiation causes many types of cancer including leukemia and cancers of the thyroid, breast and lung.
What is a carcinogen example?
A carcinogen is an agent with the capacity to cause cancer in humans. Carcinogens may be natural, such as aflatoxin, which is produced by a fungus and sometimes found on stored grains, or manmade, such as asbestos or tobacco smoke. Carcinogens work by interacting with a cell’s DNA and inducing genetic mutations.
Which is the best category of cancer causing agents?
Cancer Causing Agents – Carcinogens. “. The ” known ” category is reserved for those substances for which there is sufficient evidence of carcinogenicity from studies in humans that indicates a cause and effect relationship between the exposure and human cancer.
What are the different types of cancer and their causes?

What kind of chemicals can cause cancer in humans?
When some vegetables, like potatoes, are heated to high temps, they can give off a chemical called acrylamide. Studies show that rats who took in acrylamide in their drinking water got cancer, so researchers think humans might also.
What makes a person at risk for cancer?
Many factors influence whether a person exposed to a carcinogen will develop cancer, including the amount and duration of the exposure and the individual’s genetic background. Learn more about Environmental Carcinogens and Cancer Risk.
What chemicals are known to cause cancer?

What are carcinogens and what can cause them?
Carcinogens are substances or factors that can cause cancer. Examples can include chemicals, medical or environmental radiation, some viruses, lifestyle factors, and even some medications. Carcinogens are classified in a number of different ways as to the likelihood that they truly cause cancer, and whether this is known or only suspected.
What is a cancer causing agent known as?
Cancer causing agents are known as carcinogens. Through the cumulative effect, these carcinogens build up in our cells and cause them to mutate. There are known carcinogens and suspected carcinogens. Examples of known cancer causing agents are the hundreds of chemicals in cigarettes, asbestos and many others.
What are the main things that cause cancer?
Cancer is a disease caused by genetic changes leading to uncontrolled cell growth and tumor formation. The basic cause of sporadic (non-familial) cancers is DNA damage and genomic instability. A minority of cancers are due to inherited genetic mutations.
