kantserogeenide

Kantserogeenide are substances that have been shown to increase the risk of cancer in humans or animals. The term is derived from the Greek words "kanker" (cancer) and "rog" (harm). These substances can be classified into several categories based on their mechanisms of action and the types of cancer they are associated with. Some common examples of kantserogeenide include:

1. Certain chemicals, such as polycyclic aromatic hydrocarbons (PAHs) found in tobacco smoke and grilled meats, and aflatoxins produced by mold.

2. Viruses, like human papillomavirus (HPV) and hepatitis B virus (HBV), which can cause various types of cancer.

3. Radiation, including ultraviolet (UV) light from the sun and ionizing radiation from medical treatments.

4. Certain medications, such as anabolic steroids and some chemotherapy drugs.

The International Agency for Research on Cancer (IARC) classifies kantserogeenide into three groups based on their carcinogenicity: Group 1 (carcinogenic to humans), Group 2A (probably carcinogenic to humans), and Group 2B (possibly carcinogenic to humans). The classification is based on sufficient evidence of carcinogenicity in humans or animals.

Exposure to kantserogeenide can occur through various routes, including inhalation, ingestion, and skin contact. Prolonged or repeated exposure to these substances can increase the risk of developing cancer. Therefore, it is essential to limit exposure to known kantserogeenide and follow safety guidelines to minimize the risk of cancer.
