Malignant transformation of benign melanocytic nevus is a common cause of melanoma

Melanoma is a very common skin disease. Experts say that the cause of most malignant melanomas is related to repeated friction of melanin moles. What are the common causes of melanoma? The following is an introduction to the causes of melanoma.

What are the causes of melanoma in China ? The following is an introduction to the causes of melanoma:

1. The cause of melanoma from benign melanin nevus. That is, black nevus, among which junction nevus is most likely to become malignant, mixed nevus is less likely, and endothelial nevus rarely becomes malignant. Junctional nevus is mainly the phenotype of skin pigmented nevus in infants or children. After puberty, most junctional nevus have transformed into intradermal nevus.

2. Air pollution. The large-scale emission of harmful substances such as Freon has destroyed the atmospheric ozone layer, resulting in insufficient ultraviolet filtration. Harmful ultraviolet rays and harmful substances in the air work together to act on human skin. The cause of melanoma is that the human body is exposed to strong ultraviolet rays, which stimulates melanocytes to become malignant.

3. Immunodeficiency is one of the causes of melanoma. Practical tests have shown that circulating antibodies to tumor cell antigens have been detected in patients with malignant melanoma. Among patients with malignant melanoma, cytoplasmic antibodies have cross-reactions, while anti-cell membrane antibodies have stronger specificity.
