Mortality rate of melanoma

Melanoma is an uncommon disease, but the mortality rate of this tumor is very high. It is called the king of cancers and is more difficult to treat than liver cancer and pancreatic cancer. This disease is difficult to detect, and once discovered, it is often in the late stage. Patients usually die within a short period of time. There are many causes of melanoma, such as frequent stimulation of pigmented moles, which is related to the body's endocrine system, and is also related to daily air pollution and diet.

Causes of Melanoma

1. Frequent stimulation of pigmented nevus

There is a certain correlation between melanoma and moles. 60% of malignant melanomas are caused by the malignant transformation of pigmented moles. Most malignant melanomas occur due to repeated friction, scratching and damage to the nevus, which causes it to become malignant. Improper excavation and drug corrosion can cause benign nevus to transform into malignant melanoma.

2. Related to endocrine

Malignant melanoma develops rapidly in women during pregnancy or childbearing age, suggesting that the disease is related to endocrine system.

3. Common in benign moles

It is reported that 84% of malignant melanomas originate from benign moles. According to Wieeio, many patients do not notice the mole in the early stages of the disease because it is so small. Some people believe that benign moles are the biggest cause of malignant melanoma

4. 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.

Large-scale emission of harmful substances such as Freon has damaged the ozone layer. 5. The desire for beauty is to blame.

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.

6. 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.

7. 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.

8. Immunodeficiency

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.

9. Benign melanin plaques

That is, black moles, among which junctional nevus are most likely to become malignant, mixed nevus are less likely, and endothelial nevus rarely becomes malignant. However, most scalp melanomas are not transformed from moles, so some people believe that this disease is not entirely related to moles.
