Cancer (oncology)

Occupational cancer

Occupational cancer is defined as a blastomogenic reaction that occurs as a result of a person’s professional activity with regular, usually long-term, contact with certain exogenous chemical and physical agents that act quite intensively.

Carcinogenesis: theories and stages

It has now been established that cancer, or malignant neoplasm, is a disease of the cell's genetic apparatus, which is characterized by long-term chronic pathological processes, or, more simply, carcinogenesis, which develop in the body over decades.

Carcinogens: what are they and what are they?

The development of tumors is the result of the interaction of carcinogenic factors and the body. According to the World Health Organization (WHO), cancer is 80-90% related to environmental factors. Carcinogens constantly affect the human body throughout life.

The role of hormones in cancer development

Hormones, like carcinogens, affect the cell both through the body (indirectly) and directly, exerting a direct effect on its genetic apparatus. Hormones help reduce antitumor immunity, which creates favorable conditions for the development of malignant neoplasms.
