4 causes of melanoma

Melanoma is one of the most common skin tumors. If it is not treated in time, it is likely to cause skin cancer. This is one of the reasons why melanoma has received special attention in medicine. Experts have also made the following conclusions after long-term research on the causes of melanoma.

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, and people suspect that excessive estrogen will stimulate the occurrence of melanoma.

4. Air pollution. 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.

The main causes of melanoma are the above aspects. I hope that through the introduction of this article, everyone can pay attention to the causes of melanoma. While trying to avoid it, I also hope that everyone will actively seek treatment when they find symptoms of melanoma to prevent cancer.
