Moles are benign growths on the skin that generally do not cause any problems. A mole is a limited area of accumulation of nevus cells with pigment, formed as a result of local disturbance of melanin metabolism and synthesis. As a rule, they protrude slightly above the skin itself or are flat, smooth, sometimes they can be covered with hair.
Unfortunately, moles are not at all as harmless as they might seem. Under the influence of certain conditions - prolonged exposure to sunlight, constant friction from clothing, moles can degenerate into malignant tumors. Also, moles can form melanomas - a rather dangerous malignant disease with rapid and early formation of distant metastases, which is why all damaged moles must be removed with mandatory histological examination. An important reason for the removal of moles is their rapid growth, increase in number, change in shape or color, the appearance of pain and bleeding. Removal of moles should be carried out only in the special conditions of a medical institution, because only a doctor can safely and efficiently perform such a procedure. Before the actual removal of moles, the depth of their occurrence is determined so that the depth of exposure and the method of removal can be correctly selected. Currently, the following methods are used to remove moles: Using a surgical coagulator - electrocoagulation. Removal of a mole is performed using local anesthesia. A high-frequency electric current flows to a thin metal loop, which coagulates the surrounding tissue of the mole, and cuts it off itself. Heating of skin tissue occurs instantly, which avoids cell proliferation and bleeding. Due to the small size of the working loop, it is possible to eliminate even the smallest moles. To remove a mole, it is also surgically excised. This method is usually required to remove the most extensive formations. Increasingly, they prefer to remove a mole using a modern laser, which processes tissue in layers for 1-2 minutes under local anesthesia. Liquid nitrogen also removes moles by freezing them at a very low temperature (from -100 ° C to -180 ° C), which causes death of tissue of moles and destruction. To remove a mole, a sufficiently long exposure is carried out for more than 30 seconds with liquid nitrogen, with the applicator firmly fixed under slight pressure perpendicularly over the mole.
