Sun exposure can cause skin cancer

There are many types of skin cancer, and the causes of skin cancer are also different, so the symptoms of skin cancer are also various, some are erythematous skin lesions, accompanied by scaly desquamation, etc. Next, let's first understand the causes of skin cancer.

Chemical carcinogens

Experts say that workers who are frequently exposed to arsenic compounds, tar and asphalt are more likely to develop skin cancer. The carcinogenicity of chemical substances can be divided into two periods, namely the initiation period and the promotion period. The interval between the initiation period and the promotion period is very important, and there can be two results, namely the formation or non-formation of skin cancer. Therefore, some chemical substances may be the cause of skin cancer.

Chronic irritation and inflammation

Malignant skin tumors can occur and develop in areas of scars, chronic ulcers, fistulas, and sinus tracts. Some Asians are addicted to chewing tobacco or betel nut, so squamous cell carcinoma is more likely to occur in the mouth or lips.

Daily exposure to the sun and UV rays

There is sufficient evidence to support that the interaction between ultraviolet radiation, human melanin protection and immune system function leads to the occurrence of skin cancer. The carcinogenic mechanism of ultraviolet rays may be that the photochemical effect changes the structure of cell DNA, while destroying the active antigen structure on the surface of lymphocytes, reducing the body's immune function. Therefore, this is also the cause of skin cancer.
