Many people have pigmented moles on their bodies, often without much effect, but sometimes some moles affect the aesthetics, and some so-called “crying moles and scattered moles” affect one’s psychology. Not to mention this level, if the mole does not grow in the right place or is the wrong color, then it may be a scourge: a movie “Do Not Disturb” makes many people worry that the black dots on their body will turn into melanoma. This is how the need for mole removal arises.
Laser mole removal, you’d better take it easy
Laser mole spotting, which is crowned as “simple treatment process, safe and reliable, good effect, no complications, no side effects, easy post-operative care, and does not affect normal work and life”, has blossomed in beauty salons and has a good reputation. But it is a different situation in the hospital. When a patient bluntly asks: “Doctor, I want to have a mole, I want to use laser! But the doctor is not active, looking left, looking right, even taking out high-end equipment to take a look.
In the end, most of the patients who want to have their moles spotted with laser either give up the treatment after explanation or persuasion, or are advised to have their moles surgically removed, always bypassing the trick of “laser spotting”. Sometimes patients do not understand, thinking that doctors are playing games, wanting to do more surgery, or being irresponsible, passing the buck to patients, etc. Why is that?
Why don’t dermatologists do laser mole spotting?
Laser mole spotting, easy to recur pigmented moles are divided into intradermal moles, junctional moles or mixed moles. Some moles go deep into the dermis, and if laser mole spotting does not reach the effective depth, black spots often appear again in the pits after spotting, and some of them still recur after multiple lasers.
The moles that can be completely removed by laser mole spotting are often intradermal moles, which are usually protruding on the surface of the skin, relatively large and round, mostly black, and may also have hair on them, and are safe moles that do not need treatment.
Choosing laser mole spotting method dilemma laser mole spotting can be basically divided into two categories, invasive and non-invasive, and each of the two methods has its own disadvantages.
Invasive: carbon dioxide laser is often used to carbonize and vaporize all mole cells and pigment particles, this kind of mole spotting method is more thorough and not easy to recur, but pits and scarring may appear.
Non-invasive: Using non-invasive cosmetic laser, only the pigment in the pigmented mole is removed without destroying the skin and pigment cells, which will not leave pits or scarring, but it is easy to recur. Because the mole cells in the pigmented mole still exist, it will continue to produce pigment. In time, the pigmented nevus will return to its original appearance, and repeated laser treatments will be needed to maintain its effectiveness.
Pigmented nevi cannot be prevented. Many seekers hope to remove a large mole to prevent the growth of smaller moles around it, which is impossible.
Whether or not a mole grows in a certain area depends on whether or not the pigment cells are abnormally aggregated during embryonic development.
In other words, after laser mole spotting, it cannot prevent moles from growing in other areas.
Repeated laser nevus increases the risk of cancer. Some scholars have analyzed the pathology of recurrent pigmented nevus after laser nevus, and found that nevus cells have undergone different degrees of heterotypic changes.
This suggests that it is not just a hypothesis that repeated stimulation may cause malignant changes in pigmented moles.
The basic principle of how to remove moles scientifically is that for benign pigmented moles, it is better not to dot them; for moles that can be surgically removed, it is better not to laser dot them; and for moles that can be dotted once, it is better not to dot them many times.
Some people who seek medical treatment do point moles in order to eliminate strong psychological burden, they think this mole affects their life, fortune, feelings and so on, as a doctor, it is necessary to respect their ideas.
For moles without malignant tendency, if the patient strongly refuses surgical removal, laser can be used; however, laser mole spotting is never advocated.
Surgical excision is preferred, and in most cases we recommend surgery because.
Surgical excision can achieve the ideal scope and depth of removal in one go;
The removed mole can be scientifically determined as benign or malignant through pathological testing;
If malignant lesions are present, early detection and intervention can be made.
Surgical excision is recommended in the following cases
Moles that have been irritated by friction for a long time, such as moles that grow on the bra, waist and back of the neck, are considered to have the possibility of malignant changes due to friction.
Moles in the nail groove and under the nail. The nail groove is connected to the skin under the nail and may grow under the nail and be blocked by the nail, so that changes are not easily seen, and they grow on the extremity and have a higher chance of malignant change in the future.
Moles with irregular appearance have a high possibility of malignant change, such as blue moles, very dark moles, moles with uneven color, uneven or irregular edges, unknown boundaries, asymmetric left and right, moles with diameter larger than 0.5 cm, and moles with abnormal distribution of surrounding blood vessels.
If a single mole suddenly and rapidly changes, if a single mole suddenly and rapidly changes, appears red, swollen, itchy, painful, broken and flowing, or if several new moles suddenly appear on the side of a large mole, it indicates the possibility of malignant change and should be removed by surgery in time.
For those who have recurrence of laser mole, surgical removal is also recommended.
