You can send a photo to have a look. Generally, dark brown moles are directly removed by surgery. As for when to do surgery, generally, if the mole is relatively large and uncomfortable, you can wait for a while before treatment. After all, surgery requires general anesthesia, and the bigger it is, the safer it is. If the mole is big and fast, it must be treated early. The difference is that the early scar is small, but the risk of operation will be greater, and the later scar will be large, but the operation will be safer. This is a comprehensive choice.

The above suggestions are for reference only. Please go to the hospital for specific diagnosis and treatment under the guidance of a doctor! )
