junction mole
is usually smaller, with a diameter of 1mm~6mm, smooth, hairless, flat or slightly higher than the skin surface, hazel or dark brown spots.
Any part of the body can occur. Pigmented nevus in the palms and soles and genital areas often belong to this category, and there is no gender difference.
Mixed mole
Appearance is similar to the junction mole, but may be higher and sometimes have hair to wear.
Intradermal mole
Common in adults, papules or nodules with hemispherical shapes, diameters of several millimeters to several centimeters, smooth or papillary, or pedicle, can contain hair.
Intradermal moles generally do not enlarge. Most common on the head and neck.
Common methods for removing moles
1, surgical removal of
Generally speaking, we also recommend to remove by hand, which can reduce adverse stimulation to moles and completely remove pigmented moles.
Especially for moles with cancer risk, choose the appropriate surgical removal of (for example, the A-T flap in this figure), which can not only be completely removed, but also not easily recurrence and leave too many postoperative scars. Achieve better beauty effects.
2, laser/freeze mole
This method is more suitable for moles that are smaller and have no risk of cancer , but laser and freezing have a problem. If the depth of moles is not enough, it will easily recur or leave scars , the scars will fade slowly in the later stage.
3, chemical mole spot
Every time I go out on the street, I can see many small shops with signs for mole removal and mole removal hanging at the doors, but we do not recommend this.
First, it does not have the professional ability to judge the type and depth of mole; second, it is more likely to recur, increasing the risk of mole cancer; third, it will leave concave scars, and even larger areas than the mole itself.
Moreover, the hygiene condition of the store is unclear. If the mole removal products are not clean, it is easy to cause facial infection and affect beauty.
In recent years, the incidence of melanoma in China has shown an upward trend.
Most malignant melanomas originate from melanocytes on normal skin, and some originate from pigmented nevus.
Melanoma is the most malignant tumor among skin tumors.
How to judge whether my mole should be treated
We can judge by the ABCDE principle of melanoma.
1, Asymmetryasymmetry, ordinary black mole is round or oval, and the structure is relatively symmetrical. The black moles that may become malignant are usually irregular and asymmetric.
2, Borderline borders are irregular , and may become a black mole with melanoma. The boundaries may appear jagged or map-like changes, which suggests that the black mole may be infiltrating and invading the surrounding tissues.
3, Color Color is uneven . The color distribution of ordinary black moles is relatively uniform, but the color of melanoma is usually uneven and shows a mixture of multiple colors. It is mainly manifested as dirty black, and there may also be brown, brown, and brown. Black, blue, pink, and even white.
4, Diameter Diameter with a larger diameter , and a black mole with a diameter of more than 6mm should be closely observed.
If the mole grows further and exceeds 1cm, you should seek medical treatment in time.
The possibility of malignant changes in moles with larger diameters is significantly increased. When a doctor encounters a mole with a larger diameter, he will usually remove it completely and send it to the pathology department to diagnose benign and malignant.
5, Evolving local bulge or gradually growing . If the mole grows rapidly within a few months or six months, you need to find a specialist for further investigation.
Most moles generally do not require treatment except for beauty needs. Usually, they should reduce irritation and damage caused by external factors such as friction.
pigmented moles that occur in easily rubbed areas such as palms, waist circumference, armpits, inguinal , shoulders, etc. should be closely observed.
If moles are found with the above changes, you should go to a regular hospital for treatment in time. These symptomatic moles are no longer suitable for laser freezing and other methods to remove.
