Seven main common causes of melanoma

Melanoma can be divided into malignant and benign types, and malignant melanoma requires early treatment. So, what are the causes of melanoma ? Regarding this issue, we would like to invite experts to introduce the causes of melanoma to you, hoping that it will be helpful to you.

(1) Causes of melanoma: decreased immunity. With the improvement of living standards, the life expectancy of Chinese people has significantly increased. As people age, their immune function gradually declines. Studies have found that decreased immune function is one of the important causes of melanoma, so the incidence of melanoma in the elderly is very high.

(2) Air pollution. The large-scale emission of harmful substances such as Freon has destroyed the ozone layer, resulting in insufficient UV filtration. Harmful ultraviolet rays and harmful substances in the air work together to act on human skin, causing abnormal expression of melanocytes and triggering melanoma.

(3) The desire for beauty. The cause of melanoma is that many people use a large amount of chemical cosmetics in pursuit of clean and tender skin, causing chemical skin pollution. Some people even use chemical corrosives to remove moles on the skin, which has the opposite effect and stimulates the excessive proliferation of melanocytes.

(4) Lack of health knowledge. People do not pay enough attention to moles on the feet, perineum and other areas that are prone to friction. Due to long-term compression and friction, they eventually undergo malignant transformation.

(5) Abuse of estrogen drugs. Studies have found that there are estrogen receptors in malignant melanoma cells, so people suspect that excessive estrogen can stimulate the occurrence of melanoma.

(6) Benign melanin plaques. These are moles, of 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 this disease is not entirely related to moles.

(7) Race. The incidence rate of melanoma is higher in white people than in 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. This is one of the causes of melanoma.

The above is the introduction to the causes of melanoma, for your reference only. I believe that many people already know about the causes of melanoma. I hope the above content can help you. In addition, if you have any questions about the causes of melanoma, please consult online experts!
