cancerogena

Cancerogena is a term used to describe any substance, organism, or phenomenon that has the potential to cause cancer. This means it can increase the risk of developing cancerous cells or promote their growth. The classification of something as cancerogena is typically based on scientific evidence gathered from laboratory studies, animal experiments, and epidemiological data in humans.

The International Agency for Research on Cancer (IARC), part of the World Health Organization (WHO), is a leading authority in evaluating carcinogenicity. IARC categorizes agents into different groups based on the strength of evidence for their cancer-causing potential. These categories range from Group 1, meaning carcinogenic to humans, to Group 4, meaning probably not carcinogenic to humans.

Examples of known cancerogena include certain chemicals like asbestos and benzene, some viruses such as human papillomavirus (HPV) and hepatitis B virus, and exposure to ionizing radiation like X-rays and gamma rays. Lifestyle factors such as smoking, excessive alcohol consumption, and obesity are also considered cancerogena. Understanding what is cancerogena is crucial for public health initiatives aimed at prevention and control of cancer. Public health policies often focus on reducing exposure to known cancerogena through regulations, public awareness campaigns, and promoting healthier lifestyles.
