Mole, commonly known as “mole”, I believe that the first reaction of people who have seen “Do Not Disturb 2” is to point off, because the classic line of Li Xiangshan “got a black mole hurry to point to go, do not think that represents good luck and sexy.” The impact is far-reaching. People who have “moles” pay attention to the black moles that Li Xiangshan said, even to the extent of talking about “moles”, which made people panic. The following knowledge about “moles” may help to relieve your doubts: 1. Moles, also known as pigmented moles, can appear in any part of the body, mostly on the body surface, with a small portion growing in the nasal cavity, external ear canal, lid margin, and oral mucosa; some can be benign for life and will not become malignant, while others can become malignant. Moles growing on the face have various beautiful names, such as “beauty mole”, “lucky mole” and “hidden pearl in the eyebrow”. The black mole mentioned by Li Xiangshan is a kind of malignant tumor, also called malignant melanoma, malignant black, and we often say “mole” are two different diseases, but “mole” may become malignant black if you are not careful. 2.Do all moles need to be removed to prevent malignant transformation? (1) Moles that grow on the palms of the hands, fingers, soles of the feet, heels, toes, and the roots of the thighs and other parts that are often subject to friction are recommended to be removed surgically. (2) Moles in other areas that do not change in color, size, or shape can be removed without surgery, and frequent observation of changes in moles is sufficient. (3) If you feel that it affects the beauty or worry about malignant change, it can be removed by laser or surgery, and the treatment method should be judged by professional doctors. 3.Under what circumstances are moles prone to malignant changes? (1) It is often stimulated by artificial friction, squeezing, picking, scraping, etc. (2) Moles that recur even after repeatedly treated with potion or laser. (3) Huge moles, such as those with a diameter of more than 10cm. Almost everyone has a mole. If the color, size and shape of a mole change within a short period of time, please consult a doctor promptly; do not pick or scrape moles on purpose, and surgical removal is recommended for moles that recur even after repeated medication or laser mole spotting treatment.
