Many people are worried that the moles on their faces are too obvious. Why not find a hospital to get rid of them? Zhu Mingang, chief physician of the Department of Dermatology of the First People's Hospital of Jiashan County, Zhejiang Province, answered this question.
In fact, moles are also called mole cell moles. Everyone will have a few or dozens of moles on their body, some are congenital, and more are gradually grown out of the day after tomorrow.
Some people worry that if the mole on their face is too dark, will it happen to change? In fact, malignant melanoma is more common in Westerners, and the probability of conversion from pigmented moles to cancer is very low. However, if the mole is strongly stimulated or chronically rubbed for a long time, it may become abnormal and begin to proliferate, even spread to the whole body through the blood and lymph, and eventually become a malignant melanoma.
So, how should we distinguish between moles?

At this time, it should be noted that laser spot must not be done again. If melanoma has already occurred, laser spot will cause cancer cells to spread.
How should we prevent melanoma in daily life? The first step is to do sun protection. Ultraviolet light is an important cause of melanoma, so remember to hold an umbrella when you go out in summer, use sunscreen, wear a sun hat, etc. for protection. Secondly, don't over-contact your moles. Don't pick, rub, or stimulate. Observe at any time and go to the hospital if you find any changes. Finally, don't spot moles at will.
