Black mole on body

It is very common to have moles on the body. Most moles are related to genetics and are often located under the epidermis of the skin. Some are relatively flat, while others are higher than the skin. This type of mole needs to be noticed for changes. Although it is normal to have black moles on your body, you should also be careful to watch for malignant changes and choose to go to the hospital to remove them. It is recommended that you do not go to small beauty salons to avoid infection or unclean removal.

1. What kind of moles will grow on the body?

1. Intradermal nevus

Mole cells are located in the dermis, just below the epidermis, and often rise above the surface of the skin. The surface is smooth and may grow hair (many people call it hairy mole). This type of mole rarely becomes malignant.

2. Junctional nevus

This type of mole is flat and dark in color. The mole cells are afraid of irritation and are prone to malignant transformation if there is local trauma or infection. Junctional nevi are mostly located on the hands, feet and other parts. Be cautious about this type of mole and never blindly go to a beauty salon or small clinic for incomplete excision or laser cauterization.

3. Mixed mole

Intradermal nevus and junctional nevus coexist. This type of mole must be carefully observed. If the mole is found to become darker or larger, or to be itchy, painful, or ulcerated, you should go to a specialist hospital for regular surgery and send it for pathological examination in time. Be highly vigilant against malignant transformation into malignant melanoma.

2. Early symptoms of skin melanoma

A: Asymmetry

Ordinary moles are often round or oval, with two symmetrical halves; while malignant melanomas are often irregular in shape, and when they are divided into two, the two halves appear asymmetrical.

B: Irregular edges

Normal moles have smooth round or oval outlines. The edges of malignant melanoma are irregular or have notches or are jagged.

C: Color change

Normal pigmented moles are usually solid in color, while melanoma mainly appears as a dirty black color, but can also be brown, brown-black, blue, pink, or even white. Mixed colors are often a sign of malignant lesions, especially blue, which is an ominous sign.

D: Larger diameter

Common moles are usually smaller than 5 mm. Pay attention when the diameter is larger than 5~6 mm, or the pigmentation spot grows significantly. Pigmented nevus with a diameter larger than 1 cm is best removed for pathological examination.

E: Elevation

Some early melanomas have a slightly raised (raised above the skin's surface) appearance throughout the tumor.

In addition, early-stage melanoma may further develop into ulcers and ruptures that may not heal repeatedly; late-stage melanoma is prone to metastasis to the lungs, liver, bones, or brain, and melanoma originating from the eyes and rectum is prone to liver metastasis.
