Analysis of the causes of melanoma

Many people may not know about melanoma. In fact, melanoma is a type of tumor, mainly distributed on the surface of the skin. What are the causes of melanoma ? The following will introduce the causes of melanoma.

The cause of melanoma is still unclear, but it may be related to the following factors:

(1) Air pollution. Large amounts of harmful substances such as Freon are emitted, which damage the ozone layer and cause insufficient UV filtration. Harmful ultraviolet rays and harmful substances in the air work together to act on human skin, causing abnormal expression of melanocytes. This is a common cause of melanoma.

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

(3) Lack of health knowledge. Another reason for melanoma is that 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.

(4) Abuse of estrogen drugs. Studies have found that there are estrogen receptors in the cells of malignant melanoma. Therefore, people suspect that excessive estrogen is also a cause of melanoma.

(5) Immunodeficiency. With the improvement of living standards, the life expectancy of Chinese people has been significantly extended. As people age, their immune function gradually declines. Studies have found that low immune function is one of the important causes of melanoma, so the incidence of melanoma in the elderly is very high.

The above is an introduction to the causes of melanoma. Understanding and recognizing the causes of melanoma can help everyone better prevent and treat melanoma.
