What factors can induce the occurrence of skin cancer

Among cancer diseases, I believe everyone should be familiar with the occurrence of skin cancer. In fact, for the occurrence of skin cancer, finding the right cause is the key. Next, let's explore the causes of skin cancer .

1. Daily exposure to the sun and ultraviolet radiation: There is sufficient evidence to support the interaction between ultraviolet radiation, human melanin protection and immune system function leading to 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, and leading to the occurrence of skin cancer under the joint participation of other cancer-promoting factors. Therefore, this is one of the causes of skin cancer.

2. Ionizing radiation: In the past, radiation workers neglected protective measures, which led to radiation-induced dry skin. In recent years, due to the improvement of radiation equipment and the advancement of radiation technology, some patients who received radiotherapy still develop skin cancer in the radiation field after several years.

3. Chronic irritation and inflammation: Malignant skin cancer tumors can occur and develop in scars, chronic ulcers, fistulas, and sinus tracts. Some Asian people are addicted to chewing tobacco or betel nuts, so squamous cell carcinoma is prone to occur in the mouth or lips, leading to the cause of skin cancer.

The above are the main causes of skin cancer. I hope everyone can learn more about what causes skin cancer. If you have other questions about skin cancer, you can contact our online experts to answer your questions.
