The incidence of melanoma is caused by these causes

The incidence of melanoma is relatively high in Europe and the United States, and malignant melanoma is more common in the white race. Malignant melanoma accounts for 1% to 3% of all malignant tumors. Melanoma is one of the tumors with the fastest growing incidence, with an annual increase of about 3%. In the past 50 years, its incidence has increased about six times.

1. Causes

Melanoma cause 1: air pollution. The large-scale emission of harmful substances such as Freon has destroyed 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 and triggering melanoma.

The second cause of melanoma: immune deficiency. As living standards improve, Chinese people's life expectancy has increased significantly. As we age, our 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 clinically.

The third cause of melanoma: the desire for beauty. In pursuit of clean and tender skin, many people use a large amount of chemical cosmetics, causing 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.

Cause 4 of melanoma: Lack of health knowledge. Not enough attention has been paid to moles growing on areas prone to friction, such as the feet and perineum, which have been subjected to long-term compression and friction, eventually leading to malignant transformation.

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

2. Incidence

The incidence of melanoma is relatively high in Europe and the United States, and malignant melanoma is more common in the white race. Queens-Land in Australia is a world-renowned high-incidence area of ​​malignant melanoma.

Malignant melanoma accounts for 1% to 3% of all malignant tumors. Melanoma is one of the tumors with the fastest growing incidence, with an annual increase of about 3%. In the past 50 years, its incidence has increased about six times.

Although the incidence rate in my country is relatively low, only 0.8/100,000, it has been on the rise in recent years due to factors such as air pollution. However, doctors and patients lack awareness of its seriousness, and it is often too late when they seek medical treatment. In addition, due to irregular treatment, the treatment effect of melanoma is extremely unsatisfactory. Therefore, everyone should pay enough attention to it.
