Can removing moles cause skin cancer?

Many people are asking whether removing moles can cause skin cancer. The answer is that if you have a good physique, and the moles themselves are relatively clean, and the infection rate is low, I believe there is no problem. In fact, there are many causes of skin cancer. Let's take a closer look at them together. I hope everyone can avoid this disease in life.

1. Daily exposure to the sun and ultraviolet radiation: There is sufficient evidence to support that ultraviolet radiation, the protection of human melanin and the interaction of the immune system function lead to the occurrence 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 the specific substance or carcinogen, and its progress is irreversible, and 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 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.

3. Ionizing radiation: In the past, skin cancer occurred on the basis of radiation dry skin disease caused by radiation workers' neglect of protective measures. In recent years, due to the improvement of radiation equipment and the advancement of radiation technology, especially the strengthening of various protective measures, occupational skin cancer has basically disappeared.

4. Chronic irritation and inflammation: Malignant skin 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.

5. Others: In the immunosuppression stage, the patient's immune system is underactive and skin cancer may occur. The use of immunosuppressants can promote the occurrence of skin cancer. Viral carcinogens: Many viruses can cause cancer in animal hosts, and many subtypes of human papillomaviruses can induce skin cancer in humans.
