Analysis of the common causes of skin cancer

Many people may have heard of skin cancer. In fact, skin cancer is a relatively common oncology disease. What are the causes of skin cancer ? Here are some common causes of skin cancer.

Common causes of skin cancer include:

1. Daily exposure to the sun and ultraviolet radiation: There is sufficient evidence to support that ultraviolet radiation, the interaction between human melanin protection and immune system function are the main causes of skin cancer. When measuring human skin in sunlight, the parts of the skin that receive the most ultraviolet radiation are the head, face, back of the neck, and hands, and squamous cell carcinoma almost all occur in these parts. 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, and leading to the occurrence of skin cancer with the participation of other cancer-promoting factors.

2. Chemical carcinogens: About 100 years after Percivall first described the report of chimney sweeps being prone to scrotal skin cancer, people discovered that workers who frequently come into contact with arsenic, tar and asphalt are prone to skin cancer. Chemical carcinogenesis can be divided into two periods, the initiation period and the promotion period. The initiation period to the induced results are closely related to the exposure limit of special substances or carcinogens, and its progress is irreversible. Cell changes are related to genetics. The promotion period requires repeated exposure to the contact material, which is related to the interval time. If there is no exposure for a long time, it can still be reversed and no cancer will occur. The interval time 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. This is also a common cause of skin cancer.

3. Ionizing radiation: It is also a common cause of skin cancer. In the past, skin cancer was caused by radiation workers who neglected protective measures, which led to radiation-induced dry skin. In recent years, due to the improvement of radiation equipment and radiation technology, especially the strengthening of various protective measures, occupational skin cancer has basically disappeared. However, some patients who have received radiotherapy may still develop skin cancer in the radiation field after several years.

The above is an introduction to the common causes of skin cancer. I hope it will be helpful to everyone. Understanding and recognizing the causes of skin cancer can help everyone receive better treatment and effectively delay the disease.
