1. What happened if several black moles suddenly appeared on my neck?

Moles are very common and are generally caused by an excess of local melanocytes. It is generally benign. The commonly used methods of mole removal are as follows: laser method, freezing method, electrocautery method, spot removal machine method and chemical agent method.

2. Several common methods of removing moles

1. Chemical etching method

Indications: Moles with lighter color and shallow location.

Method: Apply 50% trinitrocarbonic acid solution or alkaline agents such as sodium hydroxide on the mole.

Advantages: Trinitrocarbonic acid solution is not easy to burn the skin and cause scars; sodium hydroxide alkaline solution is highly corrosive and takes effect quickly.

Disadvantages: The effect of trinitrocarbonic acid solution is slow, and deeper moles may need to be treated 10 times; the corrosion depth of sodium hydroxide is not easy to control and may cause deep scars.

2. Electric burning method

Indications: Moles with a diameter of 0.3 to 0.5 cm.

Method: Use the principle of electric high-temperature burning to remove the mole by burning and carbonization.

Advantages: Easy to operate.

Disadvantages: It is difficult to control the degree of burning and it is easy to leave scars.

3. Freezing method

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

Method: Use liquid nitrogen to freeze the cells around the mole, causing them to form blisters and then fall off on their own.

Advantages: The depth of destruction is relatively easy to control, it can usually be cured in one treatment, and it is not easy to cause obvious scars.

Disadvantages: Large and thick moles need to be frozen multiple times to be cured, and special instruments must be used. The doctor's skills are also very important.
