A nevus, medically known as a pigmented mole, is a benign tumor of the skin that is differentiated from nerve cells. People often say, I have grown many nevi recently. In fact, many nevus cells, which are brought out in the fetus, are just very small, and the occasional stimulating factors make it grow up.

This includes liquid nitrogen freezing, which is also not advisable. If the mole cells are stimulated, if they do not completely die and fall off, they may become malignant melanoma and it will be too late to regret. The safest method is surgical excision with cosmetic sutures, which can remove it completely in the safest way, at a higher cost and five to seven days to remove the stitches.

If it is deeper, I certainly recommend to go to surgery, and definitely will not move. In short, the breakout becomes larger early to deal with, such as to deal with a thorough!
