What Is Dermoscopy and Why You Shouldn’t Be Afraid to Get One

Imagine you have a spot on your arm that gives you a strange sensation, as if it were “vibrating” under your skin or simply causing discomfort when you touch it. This is a very common situation among my patients in Medellín. Not everyone knows exactly what is happening to them, but most feel that urgency to know or have it explained by a professional. It is frustrating to have something you do not understand and that worries you daily, especially when you see that others in your age group have already overcome those doubts.

The first thing I want to tell you is that you are not alone in that uncertainty. In my consultation, sometimes you arrive with an accelerated heart rate because the spot seems different from the ones you had last year. It is not necessary that you have panic, but rather understand what we are doing to avoid wasting time. Dermoscopy is a tool that allows us to see what is not distinguishable to the naked eye, and I will explain how it really works, without roundabout or complicated words.

How Does That Special Lens for Viewing Your Skin Work?

Think of dermoscopy as a very powerful magnifying glass with a special filter that makes blood vessels and skin texture appear much clearer. What we do is pass that light over the lesion with a 10x magnification lens, which means you see on the monitor what your eye could not capture completely. Thanks to this, we can distinguish between a benign spot, which is a joke of nature, and an alert sign that needs immediate attention.

Sometimes you wonder if it hurts or if it is invasive, but the reality is that there is no pain or needles at that moment. It is like taking a photograph of your skin with a super-detailed camera. We analyze the color pattern and the shape of the vessels to make a quick and safe decision. This allows us to identify subtle changes that could be starting to worry before the damage becomes visible to your normal vision.

Why Do These Lesions Occur and What Is Behind Them?

Suspicious spots usually appear when the skin receives too much sun, something very frequent in our city or when we travel to places with more radiation. But there are deeper causes that are not always obvious. Ultraviolet rays damage the DNA of cells, and if this happens many times, those cells can start to behave strangely and grow too fast.

Here is a very important nuance that people often ignore. Many people believe that if they find a new spot, they already have skin cancer and that nothing can change it. The reality is that treatment works better the sooner we intervene. If we detect the change in the initial stage, we can remove it with a small extraction or simple excision, without the need for long operations or complications. It is a mistake to think that it is too late; sometimes the matter lies in the first signals your body sends and that we can read thanks to dermoscopy.

In the case of melanoma, which is the most concerning type, doctors specifically look for changes in the borders of the spot or in the blood vessels within it. If we see irregular vessels or an asymmetric pattern, that indicates a cellular alteration that should not be there. It is not something that happens for nothing; it is usually a response to accumulated environmental factors over years or to genetic factors inherited from parents.

What Happens When You Call for the Consultation

When you schedule an appointment, it is normal that you first examine the spot to the naked eye to see if the spot deserves that special lens. If the suspicion is high, you go directly to dermoscopy in the consultation room. It is a quick process, it lasts a few minutes, and it does not require you to take off your entire clothes or to be placed on a large operating table.

If it turns out to be a melanoma or a malignant lesion, the next step is a biopsy, which is the extraction of a tissue sample to study it under a microscope. But we do this with all care and tranquility. If dermoscopy does not show anything serious, we simply leave you with a follow-up recommendation and give you the mental peace that everything is fine.

When Should You See a Specialist?

Do not wait for the spot to change in size or color before going to the doctor. There are concrete signs that tell you it is time to go, such as changes in the borders, which appear irregular or scalloped instead of smooth. Also if you notice that the spot has changed in shape, it is no longer round or oval as before.

Other signs are if a new bump appears on the skin, if there is spontaneous bleeding without any reason, or if you feel constant itching or pain in that area. If any of these things happen to you, do not wait for it to worsen. The best protection is prevention and early detection, and that starts by not ignoring those small signals your body shows you.

Frequently Asked Questions About the Topic

Why is dermoscopy requested if I can already see the spot with my eye? It is that to the naked eye, the microscopic changes in the vessels and in the cellular structure are not visible, which is where the real problem occurs.

Does dermoscopy hurt or leave a permanent mark after being done? It does not hurt because it does not touch the skin or make holes; it is just a light with a magnifying glass and it does not leave any visible mark at the end.

If dermoscopy says it is fine, can I have skin cancer without knowing it? It is very unlikely that you have active malignant skin cancer if dermoscopy does not show those alert signs, but it is always good to make periodic follow-ups to be at peace.
