The Moles, that according to medical term are called Nevus, are groups of pigment cells that are appeared as dark and small points in different size and colors on the skin. Moles are generally appeared on the face, arms, legs and torso but can be present anywhere of the body. Although most of skin moles are harmless and innocuous, in some rare cases change to pre-cancerous ones and they should be removed by surgery. Some patients prefer to remove their benign nevus because of aesthetics reasons using natural or surgical methods or laser to remove their face and body moles.
RF device, a type of electrosurgical or electrocautery device with high frequency is a radio frequency device that performs the surgery of different skin lesions without scars because of its specific mechanism in removing lesions and its high quality.
RF device is suitable for all aesthetics surgeries such as plastic and beauty surgery, small surgeries such as circumcision, removal of moles, warts and freckles.
What are the advantages of a real radio frequency?
Because of stopping benefit of radiofrequency waves in surface cells and at the depth of several angstroms (which are dehydrated by the waves and do not transmit the waves from itself same as hair and other dry tissues) the following positive results are obtained:
- Because the waves do not reach underlying layers of the skin such as the basal layer, probability of scar, hippo or hyperpigmentation is reduced significantly.
- The operation on skin is very comfortable, enjoyable and with the lowest pain.
RF in this clinic has the highest medical standards in the world and is designed and produced in the most reputable company with the latest technology in the world.
The cause of moles
A mole creates when melanocyte cells (the skin pigmentation cells) grow in a cluster like frame instead of spreading over the surface of the skin and come off the skin. Mole may become dark over time through exposing to sunlight during teenager period and pregnancy. During pregnancy the number of moles is often higher and the previous moles become bigger and darker.
Factors that create moles:
- Environmental factors
- Genetic background
- Sex hormones, especially estrogen and progesterone in women
Different kinds of moles:
One in 100 people has birthmark. These moles are more likely to change into melanoma (a kind of skin cancer) than others, we should be careful about them.
If the birthmark is bigger than one centimeter, it should be investigated by the doctor and removed if needed.
If the birthmark is big, hairy and thick, or if it has unnatural color, it should be removed at once.
- Awkward moles
These kinds of moles are bigger than pencils’ eraser and have irregular form. They don’t have uniform color; their center is dark brown and their edges are lighter and uneven. These moles are more likely to become cancerous. Any change in these moles should be reported to dermatologist to do the needed action if it’s necessary.
- Doubtful moles:
- Asymmetric Moles: if we draw a hypothetical line from the mole we can see that two halves do not fit exactly.
- Margin of the mole: Any uneven condition, darkness, blurry or irregularity at the edge of mole
- Color: The mole color is not uniform in all parts and they have some bronze, brown, black, blue, white and red shades.
- Diameter: The mole diameter is more than diameter of the eraser on top of a pencil.
- Transformation: the size, shape or color of mole is changing.
These kinds of moles are dangerous and should be investigated by a physician as soon as possible.
How to deal with different moles:
In suspicious moles: after investigating the mole, doctor will define that your mole doesn’t have any problem or give more medical checkups. In this case doctor remove whole the mole or at first takes a small part of it and as a sample of tissue observes it under microscope. This is biopsy as doctor said. If the mole is a cancerous one its removal will not cause cancer.
If the patient wants to remove it, doctor can remove them from the surface of skin using different methods.
Will the number of moles increase?
Some people believe that moles are male and female and can reproduce. This belief is not scientific.
Some others believe that mole removal will increase the number of them that is not true. It may reoccur after removal but removing will not cause proliferation.
Will the scars remain after removal?
Some dermatologists try to burn the moles by some special chemical substances and claim that the scar of mole will not remain on patient skin. None of the affiliated dermatologists can claim that they will perform the excision without skin scars but if during treatment the initial principles follow correctly, the scar will be faded over time for several months using topical treatments. This is a general principle but always there are some exceptions in medical science. The scar of the mole may remain after excision. In these cases, scar of surgery can be disappeared by special medical lasers.
Why some moles grow larger after removal?
Stimulation and injury of body tissues cause secretion of growth hormones and the cells in that area begin to duplicate and grow so resulting in larger moles.
Using different methods of mole removal depend on the age of patient, big or small mole, depth of mole or even its location.
Birthmarks are better to be removed by surgery because they are so deep. Small and surface moles can be completely removed by laser or even by cauter.
Complaints of mole excision
Removing the moles located on the neck and chest is likely to leave hypertrophic scar or publicly so-called Keloids. If the dermatologists follow all necessary principles to prevent this complication, it will be less probable to happen.
Usually after surgery or laser of mole, redness occurs in mole place and some days later will fade completely. In the case of mole surgery by inexperienced people, appearing scar or pore in the place is probable.
Growing back of moles is another complication that should be referred to the dermatologistand removed again.
Recurrence and return of moles:
Recurrence and return of the mole depends on the depth of mole. Deep moles usually grow back again. Recurrence of moles is related to the age of patient. Under 30 years old moles have active cells and if they do not remove completely, it is likely to grow back. In this case, doctor has to repair the returned mole. But at older ages, the chance of returning of moles is usually lower.
RF laser has higher preference in surface moles than cauter because it is much less probable for a hole to be created at the place of mole.
Does mole removal result in malignancy?
No. we rarely observe some people who get skin cancer after removing the moles in the place; this happens because some skin lesions removed by physicians as moles, are diagnosed mistakenly and are removed by a special name but they have been tumors since the first time; because these lesions are usually deep relapse and if we ignore them, they will grow back and become deeper. Therefore mole removal (if it is a real mole) will not cause any problem for the patient to be cancerous. Usually the expert dermatologist can easily identify the suspected moles before their excision and if necessary, take samples and test them.
