Analysis of the causes of melanoma

Melanoma is a common skin tumor and a malignant disease with a very high rate of canceration, which is why many people pay attention to melanoma. There is no medical consensus on the causes of melanoma. Generally speaking, the causes of melanoma can be divided into the following four aspects.

1. Race factors. The cause of melanoma may be related to race. Experts point out that the incidence of melanoma in white people is higher than that 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.

2. Immunodeficiency Immunodeficiency is also one of the causes of melanoma. With the increase of age, the immune function of the human body gradually declines. Therefore, the incidence of melanoma in the elderly is very high clinically.

3. Abuse of estrogen drugs. The occurrence of melanoma may also be related to the abuse of estrogen drugs. Studies have found that there are estrogen receptors in the cells of malignant melanoma, so people suspect that excessive estrogen will stimulate the occurrence of melanoma.

4. Air pollution. How does melanoma occur? Experts say that the occurrence of melanoma may also be related to air pollution. The large-scale emission of harmful substances destroys the ozone layer, resulting in insufficient ultraviolet filtration. Harmful ultraviolet rays and harmful substances in the air work together to act on human skin, causing abnormal expression of melanocytes, which can easily cause melanoma.

Regardless of the cause of melanoma, we need to pay enough attention to this malignant skin disease. Especially in some places, the popularization of health knowledge is not enough, and many people do not know much about melanoma, let alone do a good job of prevention based on the cause of melanoma.
