What factors are related to melanoma

The occurrence of melanoma has a great impact on the patient's life. Melanoma is a serious malignant tumor. In addition, the occurrence of melanoma has a great impact on people's appearance. So, what factors are related to the occurrence of melanoma? The following is a brief introduction.

1. Environmental factors: Exposure to ultraviolet (UV) light is an important risk factor for melanoma.

2. Atypical mole factor: Data show that the presence of atypical moles is a sign of a significantly increased risk of melanoma. About 25% of melanomas occur in the location where moles were originally present. In particular, people with atypical moles have various family syndromes, and their risk of melanoma is 100 times that of the general population.

3. Genetic factors: Family history is one of the important high-risk factors for melanoma. About 10% of patients can be found to have a family history, and the probability of melanoma in patients with a family history is twice that of those without a family history.

4. Immune factors: Experts have found that the ability of tumor cells to evade immunity is to a certain extent due to the acquisition of tolerance to natural killer cells (NK cells), thereby escaping NK killing and causing the biological behavior to deteriorate.

Warm reminder: The above is a brief introduction to the factors that cause melanoma. You should take good care of yourself in daily life. I wish you good health.
