Tumors considered professional in those cases when they occur in individuals exposed to prolonged exposure to specific industrial hazards, and are observed among certain professional groups are much more common than among the surrounding population.The largest share among professional has cancer tumors of various organs.It usually occurs in running after prolonged exposure to occupational factors and are often several years after the termination.However, isolated cases described in the rapid development of the tumor.
Skin cancer is the most common form of occupational cancer.It is observed in individuals exposed to ionizing radiation and X-rays, gamma rays and other types of radiation (X-ray staff rooms, staff for testing X-ray tubes, work on accelerators, betatons, gamma settings, and so on. D.).
Skin cancer also occurs in people who have prolonged contact with products of the distillation of coal, oil and shale (tar, pitch, anthracene oil, tar, wax, etc.).It is -. The workers of chemic
In establishing a professional etiology are important localization of lesion and its compliance with the place of exposure to workplace factors (professional tumors of the skin are more common in open areasthe body - the face, neck, scalp, arms).
Professional nasal cancer, paranasal sinuses
Professional nasal cancer and paranasal sinuses is observed among workers who have contact with the nickel compounds (a carbonyl, and nickel sulphate and chloride in the preparation of the latter by means of electrolysis).
Professional laryngeal cancer
Professional larynx cancer in workers dealing with coal tar.Cancer of the upper respiratory tract in both developed through many years (more than 15) after the start of the specified substances.
Lung cancer occurs in persons who are in a professional activity of respirable dust (or a couple) of radioactive ores, coal tar, nickel compounds (especially nickel carbonyl), arsenic, chromium, asbestos, beryllium, and others. (Miners onexploration, mining and processing of radioactive ores, workers, commas in loading and application of coal tar, nickel compounds, arsenic and others.).
Professional lung cancer (as well as non-professional) is more common in men;workers younger observed more often (in contrast to the non-professional nature of the cancer).
of cancer, seems to contribute to the impact of professional and other factors, as well as the presence of associated pulmonary diseases.It is known that the presence of asbestosis predisposes to the development of lung cancer.It is believed that pulmonary fibrosis is toxic to some extent, a precancerous condition.
Bladder tumors (papilloma, cancer) are found in individuals with long-term contact with amines of the benzene and naphthalene series in the chemical, textile and other industries.Routes of compounds in the body and their selection.Professional bladder tumor can be either benign (papillomas) and malignant.The general condition of the patients is often strikingly long remains intact.The main symptom of tumors of the bladder - hematuria.
tumors at other sites
tumors at other sites are much rarer.Malignant neoplasms of bone observed in individuals with long-term contact with the bone-seeking radioactive substances.It - radiochemical workers, radiological laboratories, etc.
acute leukemia, chronic myeloid leukemia and other malignant neoplasms of the blood may occur in workers exposed to ionizing radiation, benzene...
clinical and histological picture of a professional skin cancer, upper respiratory tract, lung, bladder tumors is not different from other etiologies.The etiologic diagnosis is made on the basis of carefully collected professional and proven history of patient and prolonged contact with carcinogens.
It should be emphasized that occupational cancer can also occur in a few (5-8) years after termination of contact with carcinogens.This circumstance makes it necessary for the long-term clinical observation working with a lot of professional experience, worked primarily with carcinogens.
