It is normal for many small moles to appear on the body and patients do not need to be particularly alarmed. Moles are benign skin tumors formed by the aggregation of nevus cells in clinical practice, and moles will slowly increase with age. Many times, the local occurrence of pigmented moles may be related to genetic or hormonal changes or trauma. If there are many small moles growing on the body, patients are usually not recommended to deal with them because even after removing the moles, they can occur again, possibly reappearing on top of the original moles or occurring new ones in other areas. Therefore, it is generally impossible to remove moles from the whole body in clinical practice. If patients look closely at the people around them, they will find that there are more or less moles on other people.
