What is the cause of malignant melanoma?

The incidence of melanoma is increasing year by year. This disease can be divided into benign and malignant. Whether it is benign or malignant, it is caused by some adverse factors, and the body will be harmed in many ways. Therefore, it is necessary to find out the cause in time and then treat it. So what is the cause of malignant melanoma?

There are many reasons for the occurrence of malignant melanoma. It may be caused by light exposure, that is, ultraviolet radiation. Ultraviolet radiation is a major cause of malignant melanoma. Ultraviolet rays are very sensitive to DNA damage and can cause a decrease in systemic immunity. There is a lot of information proving the pathogenic effects of sunlight and ultraviolet rays. Of course, it may also be caused by racial genetics. Generally, it occurs in Caucasians. Sixty-seven percent of patients develop on existing moles. Familial malignant melanoma is increasing. Epidemiological data show that the probability of Caucasians developing malignant melanoma is much higher than that of other people of color.

Another possibility is that the original pigmented nevus has undergone malignant changes. Some people believe that patients with more than 20 moles on their skin have a three-fold higher chance of developing malignant changes. The junctional components of junctional nevus and mixed nevus can become malignant melanoma. Everyone knows this. In addition, it may be caused by dysplastic nevus syndrome or the endocrine system.
