Many people have moles on their bodies. Some people don’t take it seriously, while others are worried about them. Should these moles be removed? If I want to go, how to get there?

Nevus is formed by the accumulation of melanocytes located at the junction of the epidermis and dermis of the skin. Depending on the number of nevus cells, it can be higher than the skin surface or level with the skin. It can vary in size and location. If they are not consistent, they can grow first and later. There is a folk theory about mother and child moles, but in fact there is no scientific basis.

Since it is difficult to judge the depth of a mole from its appearance, you have to be careful when removing it. The so-called one-time mole spotting method introduced by some beauty salons is risky. Although very shallow moles can be removed, the epidermis is very thin. If you are not careful, it is easy to remove the entire epidermis, leaving scars, and the scars are permanent. The scars are not as effective as the advertisement says, and they will disappear as soon as they are removed. However, if the mole is deep, it is not easy to remove it by the above method. It will grow back after the treatment, or even become larger. The result will be scars and lingering moles, which will make it more unsightly. What's more serious is that if the mole is repeatedly stimulated or infected, it can easily induce malignant transformation and become a highly malignant tumor.

Of course, moles are not impossible to remove. Moles that are higher than the skin surface can be removed by freezing, surgery or laser. These methods also have the risk of leaving scars. Nowadays, there is a laser emitted from a gemstone. Use it to illuminate the area where the mole is. When it reaches a certain energy, the mole will explode like a hot air balloon. We call it biological detonation treatment. The cells or pigment particles turn into tiny pieces. The particles will be removed by the body's tissue cells, so the color will slowly fade or disappear. Although this method does not damage the epidermis and has a small chance of leaving scars, it needs to be done several or more than a dozen times, with an interval of more than three months each time. The entire treatment takes a long time and costs a lot.

Mole that need to be vigilant and removed

Generally speaking, the chance of malignant transformation of moles is still very small, but if the skin is white and often exposed to the sun, the malignant transformation of moles will increase. opportunity. There are also some signs of malignant transformation of moles: For example, a mole suddenly becomes larger, becomes darker in color, has itching or pain, or has local ulcers, or small moles grow around the mole. These are undesirable phenomena and you should go to the hospital as soon as possible. Moles on the palms and soles of the feet increase the chance of malignant transformation due to frequent friction and should be removed as soon as possible.

But before mole removal, it is best to conduct a pathological examination and observe whether there are malignant cells under a microscope. If there is no malignant change, it can be surgically removed. If there are signs of malignant change, large-area dissection and other operations should be performed. treat.

If the mole is smaller, use laser to remove it. If the mole is deeper, minor surgery will be required!

Comprehensive methods of removing moles:

1. Chemical drugs

There are strong acid or alkali chemicals on the market for cauterization, while hospitals use trichloroacetic acid to spot moles. It is more effective for newly appeared and relatively shallow combined moles, which are often caused by excessive cauterization. Depressed scars, or raised scars due to scar constitution.

2. Electric cautery

It is effective for superficial combined moles and deeper and raised compound moles.

The operation is difficult to control and can easily cause scars.

3. Freezing

Freeze moles with liquid nitrogen.

It can effectively remove protruding and flat moles.

Because it is difficult to control the depth and often causes damage, dermatologists currently do not use it to treat moles.

4． Surgical excision

can be removed once and for all. If there is a mole that may become malignant, pathological tissue examination can be performed after the removal.

Resection is a type of surgery, so it requires anesthesia and suturing, and the wound is difficult to take care of.

5. Laser vaporized nevus

Except for spot bleeding that may occur after some laser surgeries, there are no traces after demobilization.

Only suitable for shallow moles, because residual melanocytes under the skin will surface again and again, requiring multiple laser treatments

It is a bit difficult to save eyebrows

There are many plastic surgery methods at present, and each method has its own advantages and disadvantages. You should first let the doctor examine the condition of the mole and make suggestions before making a decision.

Electric cautery method

Method: Apply the principle of electric high-temperature burning to remove moles due to cauterization and carbonization.

Advantages: Easy to operate, even some beauty salons can operate it.

Disadvantages: Difficult to control the degree of burning and easy to leave scars. Indications: Moles with a diameter of 0.3-0.5 cm.

Laser mole spotting method

Method: At present, superficial moles can be removed using laser, such as ruby ??laser, chromium laser or dye laser; Deep moles should be removed using carbon dioxide ultra-pulse laser.

Advantages: Laser mole removal can control the size and depth of the optimal light spot, and is less likely to leave scars and infections.

Disadvantages: Moles that are too deep may still need to be treated in separate treatments. Indications: Most can be used, including dark and light moles.

Surgical excision method

Method: Surgically remove the diseased tissue around the mole.

Advantages: This method can choose to partially or completely remove the diseased tissue, and different treatment methods can be carried out depending on the nature of the mole.

Disadvantages: It is difficult and takes a lot of time. This method is rarely used for general moles.

Indications: Large and raised moles with a diameter of more than 0.6 cm.

Chemical etching method

Method: Generally, a 50% trizocarbonate solution or an alkaline agent such as sodium hydroxide is applied to the mole.

Advantages: trizocarbonate solution is not easy to burn the skin and cause scars; alkaline solution is highly corrosive and may be effective quickly.

Disadvantages: The effect of trizocarbonate solution is slow, and it may be applied up to 10 times for darker moles; sodium hydroxide is not easy to control the depth of corrosion and may cause deep scars.

Indications: Moles that are lighter in color and lighter in location.

Freezing method

Method: Freeze with liquid nitrogen to freeze the nevus tissue very quickly, causing the cells around the nevus to form water sores and then fall off on their own.

Advantages: The depth of damage is relatively easy to control, it can usually be done in one go, and it is not easy to cause obvious scars.

Disadvantages: Large and thick moles need to be frozen several times before they can be removed, and special equipment is required. The doctor's skills are also very important.

Indications: Flat moles with a diameter of 0.3-0.5 cm, including freckles.
