Respiratory tract tumors account for a large proportion of occupational tumors. At present, arsenic, arsenic,
Occupational skin cancer is the earliest occupational tumor found, accounting for about 10% of human skin cancer. The relationship between occupational skin cancer and carcinogens is often the most direct and obvious, and it often occurs in the contact area of the exposed site. The main chemicals that can cause skin cancer are: coal tars, asphalt, paraffin, chloroprene, arsenic, etc. Coal tar-like substances are the most common skin cancers of workers. The coal tars mainly contain benzo (a) pyrene, which is the most carcinogenic, and a small amount of other polycyclic aromatic hydrocarbons, which are less carcinogenic.
Exposure to inorganic arsenide can induce skin cancer. The clinical manifestations were early hyperkeratosis, hyperpigmentation, and ulcer formation on the limbs and facial skin. These changes belong to precancerous lesions and further develop into squamous cell keratinoma or adenocarcinoma. According to a survey of an arsenic mine in Hunan, 16 cases of skin cancer were found between 1976 and 1998, accounting for 8% of malignant tumor cases; and about 1/4 of lung cancer complicated by skin cancer.
Epidemiological investigations indicate long-term exposure to X

Exposure to vinyl chloride can cause hepatic angiosarcoma, which is more common in cleaners exposed to high concentrations of vinyl chloride, with incubation periods ranging from 10 to 35 years.
Exposure to high concentrations of benzene can cause leukemia, most of which occur years to 20 years after exposure to benzene, the short one being only 4 to 6 months, and the elderly up to 40 years. Benzene poisoning
Occupational tumors and non-professional tumors have no difference in the course of disease development and clinical symptoms. However, occupational tumors have their specific parts, and occupational tumors are legally compensated for occupational diseases. Therefore, in April 2002, our government listed eight occupational tumors as
Occupational tumors have clear pathogenic factors, so effective countermeasures can be taken to prevent them. The main methods are: identification, identification, strict control and management of occupational carcinogens, regular medical monitoring of contacts, screening of high-risk groups, Regulations are adopted to ensure its implementation; carcinogenic occupational factors in the production environment should be monitored regularly to keep their concentration or intensity below the national occupational health standards. Secondary prevention such as regular physical examination, early detection, and timely diagnosis and treatment are proven effective measures and should be clearly defined as a prevention system for occupational tumor factor contacts. And if it is found to have occupational tumors, comprehensive treatment of tumor typing should be used in time.
