Four common causes of melanoma

Although the incidence of melanoma is not very high in clinical practice, the harm of melanoma to patients is not small. What are the causes of melanoma ? Here are some common causes of melanoma.

Common causes of melanoma include:

1. Insufficient UV filtration causes skin damage. Air pollution and large-scale emissions of harmful substances such as Freon have destroyed the ozone layer, resulting in insufficient UV filtration. Harmful UV rays and harmful substances in the air work together to act on human skin, causing abnormal expression of melanocytes, which is the most common cause of melanoma.

2. Malignant transformation of moles Benign melanin plaques are moles, among which junctional moles are most likely to become malignant, mixed moles are less likely, and endothelial moles rarely become malignant. However, most scalp melanomas are not transformed from moles, so some people believe that the cause of melanoma is not entirely related to moles. Lack of health knowledge has not caused enough attention to moles growing on the feet, perineum and other parts that are prone to friction. Due to long-term compression and friction, they eventually undergo malignant transformation.

3. Abuse of estrogen drugs is also a common cause of melanoma. Studies have found that there are estrogen receptors in the cells of malignant melanoma. Therefore, people suspect that excessive estrogen will stimulate the occurrence of melanoma. The incidence rate of white people is higher than that of people of color. For example, the annual incidence rate of white people in the United States is as high as 42/100,000, while that of black people is only 0.8/100,000.

4. Chemical skin pollution and the desire for beauty. Many people use a large amount of chemical cosmetics in pursuit of clean and tender skin, which causes chemical skin pollution. Some people even use chemical corrosives to remove moles on the skin, but the result is counterproductive and stimulates the excessive proliferation of melanocytes, which is also a common cause of melanoma.

The above is an introduction to the common causes of melanoma. I hope it will be helpful to everyone. Once you have melanoma, you must go to a regular hospital for treatment immediately to avoid delaying the disease.
