The details of the classifications are as follows: Group 1: Carcinogenic to humans. Sufficient evidence in humans. E.g.: aflatoxins , alcoholic beverages, B[a]P , cadmium , Chinese-style salted fish , chromium (VI) compounds , dioxins and dioxins-like PCBs , and processed meat .

What are the different types of carcinogens for humans?
Category 1A: includes substances whose potential carcinogenicity for humans is known; classification in this category is primarily based on human data. Category 1B: includes substances whose carcinogenic potential to humans is presumed, classification in this category is primarily based on animal data.
How are carcinogens classified in the European Union?
Classification of the European Union (CLP) Category 1A: includes substances whose potential carcinogenicity for humans is known; classification in this category is primarily based on human data.

What kind of agent can cause cancer in humans?
Carcinogen, any of a number of agents that can cause cancer in humans. They can be divided into three major categories: chemical carcinogens (including those from biological sources), physical carcinogens, and oncogenic (cancer-causing) viruses.

Can a carcinogen cause cancer in every person?
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.

Are all carcinogens also mutagens?
A carcinogen is any agent that directly increases the incidence of cancer. Most, but not all carcinogens are mutagens. Carcinogens that do not directly damage DNA include substances that accelerate cell division, thereby leaving less opportunity for cell to repair induced mutations, or errors in replication.
