There are dozens to hundreds, depending on the level of the hospital and the method used. The method of mole removal usually depends on the type, size and location of the mole. There are methods such as resection, laser, and liquid nitrogen freezing. It is recommended that you go to a professional hospital and have a doctor look at it. In Zhangjiagang, you can go to Wuxi Tongji Plastic Surgery Hospital. One of my classmates had mole removal done there, and the results were very satisfactory. It is a relatively regular hospital, so you can feel more at ease while doing it. I suggest you go to Baidu to learn more, I hope it can help you.
