In addition to aesthetic factors, in order to avoid turning into malignant melanoma, the following moles should be removed:

1). Moles that will be stimulated by long-term friction, such as when wearing a bra Moles on the buttocks and waist.

2). Moles with atypical changes. Moles with atypical appearance may become malignant, such as very dark moles with uneven pigmentation (variegated colors), uneven or irregular edges, unclear boundaries, left and right asymmetry, and statistically greater than 5 mm in diameter.

3). A single mole changes suddenly and rapidly. If the moles all over the body change at the same time due to changes in hormones, there is no doubt. If a single mole changes suddenly and rapidly, it is worth noting.

4) Moles growing in special parts. For example, moles that grow on the extremities (hands and feet) must be carefully observed, because moles in these places have a greater chance of becoming malignant melanoma than moles in other places.

5). Moles on the mucous membrane. Moles on the oral mucosa, conjunctiva, vagina, and foreskin.

6). Moles in nail grooves. The nail groove is connected to the skin under the nail. It may grow under the nail and be blocked by the nail. It is not easy to see the change. Moreover, if it grows on the extremity, it will have a greater chance of becoming malignant in the future.

7). Some moles themselves are inherently high-risk moles. Moles that are visible when a baby is born are called congenital moles. There are not many congenital moles. According to statistics, 1% of newborns have moles. Not all congenital moles are dangerous at birth. Size is an important factor. Generally speaking, larger moles have a greater chance of becoming malignant in the future, so doctors recommend that they be removed as soon as possible.

Some people have a constitution with swollen feet (that is, a scar constitution). Scar tissue will proliferate abnormally, resulting in hypertrophic scars. Crabfoot is common in earlobes, shoulders, upper arms, chest and back, and is not a common site on the face. If people with this kind of constitution want to remove moles for cosmetic purposes, they should inform the doctor about their constitution first to prevent moles from causing big scars.

3. What are the commonly used methods to remove moles?

The method of mole removal usually depends on the type, size and location of the mole.

1). Excision

As long as it is suspected to be malignant, it must be excised and biopsied. Laser may not be able to clean it completely. Compound nevus and dermal nevus are too deep and protruding. If they want to be removed, excision is required. Larger moles need to be sutured after being removed, and even skin grafting (transferring a piece of skin from elsewhere) and skin flap transfer (taking over the adjacent flesh) are required.

2).Laser

Laser is a treatment method that converts electrical energy into light. It is suitable for smaller and shallower moles, such as flatter moles.

3). High frequency electrocautery

Use heat energy to destroy cells.

4). Liquid nitrogen freezing

It can be destroyed by the low temperature of minus 196 degrees Celsius, but it is rarely used.

5). Drug mole removal

There are two types. One is to use biotechnology to remove moles with traditional Chinese medicine such as Tianjian Mole Meijing. It has good effect, fast speed and is not easy to leave. Remove scars; one is chemical etching to remove moles. The disadvantage is that it is difficult to control the depth and range of the burn. If the spot is damaged, holes will appear, and some holes are very deep;

So you need to be careful when choosing the medicine. Identification;
