Any chemical or physical agents by which cancer can be caused are known as Carcinogens.
Based on their mode of action, carcinogens can be divided into the following main categories:-
(i) Agents that can cause alternations in the genetic material that is DNA which may resulting in oncogenic transformation that can lead to cancer like varius types of radiations and chemicals.
(ii) Cancer causing DNA and RNA viruses or tumour viruses which have been shown to be associated with oncogenic transformation.
(iii) Agents that promote the proliferation(rapid increase) of cells, which have already undergone genetic alterations responsible for oncogenic transformation. Agents of this type are known as tumor promoters like growth factors and hormones.
