Most people have heard that an unusual mole can be a warning sign of skin cancer. But skin cancer does not always look like the dark, irregular mole you may have seen on a poster in a doctor’s office.
Sometimes it looks like a small pink bump. It may resemble a pimple that never completely disappears, a rough patch that repeatedly forms a scab, or a tiny sore that bleeds when you wash your face. In other cases, the most important clue is not what a spot looks like at all, but the fact that it has started behaving differently.
That can make skin cancer surprisingly easy to overlook.
At Wasatch Dermatology, our dermatology team evaluates suspicious lesions, performs comprehensive skin examinations, diagnoses skin cancer, and provides treatment options, including Mohs surgery. Knowing what deserves a closer look can help you recognize when it is time to schedule an examination rather than continuing to watch a spot at home.
Here are seven changes dermatologists want you to pay attention to, including several that go well beyond the traditional ABCDE rule.
1. A Mole That Is Changing
The ABCDE rule remains one of the most useful ways to remember common warning signs of melanoma:
- A: Asymmetry. One half of the mole does not resemble the other.
- B: Border. The edges appear irregular, blurred, scalloped, or poorly defined.
- C: Color. The spot contains multiple colors or develops changes in pigmentation.
- D: Diameter. Melanomas are often larger than 6 millimeters when diagnosed, although they can be smaller.
- E: Evolving. The mole changes in size, shape, color, elevation, or another characteristic.
Of these, evolving is particularly important.
Your skin naturally contains spots that look different from one another. You may have freckles, birthmarks, seborrheic keratoses, moles, and other benign growths. What deserves attention is a lesion that begins behaving differently from its previous pattern.
Maybe a mole you have had for years becomes noticeably darker. Perhaps it begins growing outward, develops a new color, changes shape, or becomes raised.
The change does not automatically mean you have melanoma. However, a changing lesion should be evaluated rather than diagnosed from photographs or monitored indefinitely at home.
Pay Attention to the “Ugly Duckling”
Another useful concept is the ugly duckling sign.
Most people’s moles tend to share certain characteristics. They may be similar in size, color, or shape. A mole that looks noticeably different from the others may therefore warrant closer attention, even if it does not perfectly meet every ABCDE criterion.
When checking your skin, do not simply ask, “Does this mole look bad?”
Ask, “Does this spot look different from the rest of my spots?”
That comparison can sometimes make subtle changes easier to recognize.
2. A Sore That Will Not Heal
One of the easiest skin cancer warning signs to dismiss is a sore that simply refuses to go away.
You may initially assume you scratched yourself, nicked the area while shaving, irritated your skin, or picked at a blemish. It forms a scab, appears to improve, and then opens again.
The cycle repeats.
A persistent or recurrent sore can be associated with certain types of skin cancer, including basal cell carcinoma and squamous cell carcinoma.
These lesions do not necessarily look dramatic. A non-healing area might appear as:
- A small open sore
- A crusted patch
- A pink or red irritated area
- A spot that repeatedly scabs
- An area that seems to heal and then returns
- A lesion that occasionally oozes or bleeds
The duration matters.
Most everyday cuts, blemishes, and minor skin injuries gradually improve. If a spot continues to break down, scab over, reopen, or remain irritated without a clear explanation, it deserves professional evaluation.
This is particularly important in chronically sun-exposed areas such as the face, ears, scalp, neck, arms, and hands.
3. A Shiny, Pearly, or Translucent Bump
Not every skin cancer is dark. In fact, basal cell carcinoma can sometimes appear as a flesh-colored, pink, pearly, or translucent bump. Because the lesion can look smooth and relatively harmless, patients may assume it is a pimple, scar, enlarged pore, or another benign growth.
A basal cell carcinoma may have a shiny or waxy appearance. Tiny blood vessels may also become visible across its surface.
These lesions frequently develop in areas that receive substantial cumulative sun exposure, particularly the face and neck.
One clue is persistence.
A typical pimple evolves. It becomes inflamed, changes, heals, and eventually disappears. A suspicious bump may remain in essentially the same location for weeks or months. It may slowly enlarge, develop a central indentation, crust, or bleed.
If you have been waiting for a “pimple” to disappear and it simply does not, especially if it is on a sun-exposed area, having a dermatologist examine it is a sensible next step.
4. A Rough, Scaly, or Crusted Patch That Keeps Returning
Skin cancer does not always form a distinct bump or mole. Sometimes the first thing you notice is texture.
A suspicious area may feel rough when you run your finger across it. It might appear pink or red, develop scales, or repeatedly form a crust.
Some precancerous lesions and squamous cell carcinomas can present this way.
This becomes especially easy to overlook in Utah, where dry weather can make rough, flaky skin seem completely ordinary. You may assume the spot is simply dry and continue applying moisturizer. But ordinary dryness tends to respond, at least temporarily, to hydration and changes in skincare.
A persistent isolated patch is different.
If the same small area remains rough while the surrounding skin feels normal, repeatedly scales after you remove the flaking skin, or continues returning despite moisturizing, it is worth showing your dermatologist.
What About Actinic Keratosis?
A rough or scaly area may also be an actinic keratosis, a precancerous growth caused by cumulative ultraviolet exposure.
These lesions often develop in areas that receive substantial sun exposure, including the scalp, face, ears, forearms, and backs of the hands. They may feel easier to detect by touch than by sight.
Not every actinic keratosis progresses to skin cancer, but some can develop into squamous cell carcinoma. That is one reason dermatologists evaluate and, when appropriate, treat these lesions rather than simply assuming they are harmless dry skin.
5. A Spot That Bleeds With Very Little Provocation
Healthy skin generally should not bleed from lightly washing your face, drying your face with a towel, or brushing against it.
A lesion that repeatedly bleeds with minimal contact deserves attention.
You might notice blood after shaving over the same area, while washing your face, when scratching what you thought was a dry patch, or simply when waking up in the morning.
Skin cancers can be fragile, which means the surface may break down and bleed more readily than surrounding healthy skin.
The key word is repeatedly.
Accidentally scratching a mole once does not mean it is cancerous. The concern is a lesion that seems unusually prone to bleeding, particularly when accompanied by other changes such as growth, crusting, ulceration, color changes, or failure to heal.
Spontaneous bleeding, meaning a lesion begins bleeding without any obvious trauma, should also prompt evaluation.
Rather than continuing to blame your razor, towel, glasses, or fingernail, let a dermatologist determine why the area keeps breaking down.
6. A New Growth That Is Getting Bigger
New spots appear on our skin throughout life, and most are benign.
That makes it tempting to ignore a new bump, patch, or growth, especially when it is small.
What dermatologists care about is the pattern.
A lesion that appears and then steadily grows deserves more attention than one that remains stable. Depending on the type of skin cancer, the growth may be slow and subtle rather than dramatic.
For example, squamous cell carcinoma can present as a firm red bump, a scaly patch, a crusted growth, or a sore. Basal cell carcinoma may present as a shiny bump, a scar-like area, or a non-healing lesion. Melanoma can develop within an existing mole or appear as a new pigmented lesion.
This is why waiting for a spot to become “obviously bad” is not a good screening strategy.
You do not need to know what type of lesion you are looking at before making an appointment. That is the dermatologist’s job.
Your job is simply to notice that something has changed.
What About New Moles?
New moles are common in younger people, but a new pigmented lesion developing later in adulthood may deserve closer attention, particularly when it looks different from your existing moles.
Again, a new mole does not automatically equal melanoma. Dermatologists look at the complete clinical picture, including your age, personal and family history, sun exposure, appearance of the lesion, and whether it has changed.
If you are uncertain, having the spot examined is more reliable than trying to diagnose it yourself.
7. A Spot That Suddenly Starts Itching, Hurting, or Feeling Different
Appearance gets most of the attention when we talk about skin cancer, but sensation can change, too.
A lesion that was previously unremarkable may begin to:
- Itch persistently
- Feel tender
- Hurt
- Tingle
- Become sensitive
- Bleed
- Feel different from the surrounding skin
There are many benign reasons for itching and tenderness, so these symptoms alone do not diagnose skin cancer.
The context matters.
A mole that becomes itchy and changes color or shape deserves attention. So does a growth that becomes tender while steadily enlarging or a scaly lesion that repeatedly hurts and bleeds.
The bigger lesson is to pay attention when a spot changes its behavior.
Patients sometimes hesitate to mention these subtle symptoms because they seem insignificant. From a dermatologist’s perspective, however, the history of a lesion can provide valuable information.
Skin Cancer Does Not Always Look Like the Pictures Online
Searching for images of skin cancer can be useful for general education, but it also creates a potential problem: patients begin looking for an exact match.
Real skin does not work that way.
Basal cell carcinoma, squamous cell carcinoma, and melanoma can each have different appearances. Skin cancers may also look different depending on skin tone, location, stage, and individual characteristics.
A lesion does not need to resemble the most dramatic photograph in an online image search to deserve evaluation.
This is especially important for people with darker skin tones. Although skin cancer is less common in people with more deeply pigmented skin, it can still occur and may sometimes develop in areas patients do not associate with sun exposure.
The palms, soles of the feet, beneath the nails, and other less obvious areas should not automatically be excluded from self-examination.
How Often Should You Check Your Own Skin?
Getting familiar with your skin can make changes easier to recognize.
Periodically examine areas you can see easily, but do not forget places that receive less everyday attention. That includes:
- Scalp
- Behind the ears
- Back of the neck
- Back
- Buttocks
- Backs of the legs
- Between the toes
- Soles of the feet
- Around and beneath the nails
A mirror can help with difficult-to-see areas, and a partner or family member may be able to check your scalp and back.
If you have many moles, taking clear photographs can also help you recognize whether a particular lesion has changed over time. Photos should complement, not replace, professional skin examinations when they are recommended.
Who Is at Greater Risk for Skin Cancer?
Anyone can develop skin cancer, but certain factors can increase risk.
These include a history of significant sun exposure, repeated sunburns, indoor tanning, fair skin, light eyes or hair, numerous or atypical moles, a weakened immune system, increasing age, and a personal or family history of certain skin cancers.
Living an active lifestyle can also mean accumulating more UV exposure than you realize.
In Utah, skiing, hiking, running, cycling, golfing, boating, and other outdoor activities can translate into substantial lifetime sun exposure. UV radiation also does not disappear during colder weather, and snow can reflect ultraviolet rays.
That makes year-round sun protection important, not simply sunscreen use during summer vacations.
When Should You See a Dermatologist About a Spot?
You do not have to wait until you are certain something is skin cancer.
Schedule an evaluation if you notice a lesion that:
- Is new and continues growing
- Looks noticeably different from your other spots
- Changes in color, size, shape, or texture
- Repeatedly bleeds or crusts
- Does not heal
- Becomes persistently itchy, painful, or tender
- Develops irregular borders or multiple colors
- Simply concerns you
There is no prize for successfully diagnosing a suspicious lesion on your own. The purpose of a dermatology evaluation is to determine what it actually is.
If a dermatologist identifies an area that warrants further investigation, a biopsy may be recommended. A small tissue sample can then be examined to determine whether abnormal or cancerous cells are present.
What Happens If Skin Cancer Is Found?
Treatment depends on the type, size, depth, location, and other characteristics of the cancer.
Options can include surgical excision, destruction techniques, topical treatments for selected superficial cancers, and other approaches. For certain skin cancers, particularly those occurring in cosmetically or functionally important areas, Mohs micrographic surgery may be recommended.
Mohs surgery removes skin cancer in carefully controlled layers. Each layer is examined microscopically while the patient remains at the office, allowing the surgeon to continue until no cancer cells are detected at the margins while preserving as much healthy surrounding tissue as possible.
At Wasatch Dermatology, patients benefit from an experienced team dedicated to the prevention, detection, and treatment of skin cancer. Dr. Julie A. Maughan, a board-certified dermatologist and Fellow of the American Academy of Dermatology, has continued her family’s tradition of comprehensive dermatologic care in Weber County since joining the practice in 2007.
She is joined by Dr. Emily Powell, a board-certified dermatologist and Mohs surgeon with advanced fellowship training in dermatologic oncology and micrographic surgery, and M. Elizabeth Hughes, PA-C, a certified physician assistant who contributes to the practice’s comprehensive approach to dermatologic care.
Together, the Wasatch Dermatology team provides skin cancer screenings, evaluation of suspicious lesions, diagnosis, treatment, and access to Mohs micrographic surgery when appropriate, allowing patients to receive coordinated care for their skin health in one practice.
Do Not Wait for a Spot to Look “Scary”
Perhaps the most important thing to understand about skin cancer is that early warning signs can be remarkably ordinary.
It might be the tiny scab you keep picking because you assume it is dry skin. The “pimple” beside your nose that has been there for three months. The spot on your scalp your hairstylist keeps noticing. The mole that looks just a little darker than it did last summer. Or the sore on your ear that seems to heal before opening again.
None of these signs automatically means you have skin cancer.
But they are worth paying attention to.
Skin cancer screening is not about becoming suspicious of every freckle or bump. It is about learning what is normal for your skin and recognizing when something is new, changing, persistent, or simply does not behave the way ordinary healthy skin should.
