Mole Check 101: When a Spot Needs a Dermatologist and Why Skin Exams Matter
An annual skin exam is one of the simplest ways to stay proactive about your skin health. For most patients, the appointment takes about 15 minutes and is designed to identify concerning spots before they become larger problems. Whether you've noticed a new mole, have a changing spot, or simply want peace of mind, a skin exam is a routine part of preventive dermatologic care.
Many people delay scheduling because they aren't sure what to expect. Fortunately, the process is straightforward, comfortable, and focused on helping you better understand your skin.
What Happens at a Skin Exam?
If you've never had an annual skin exam, you may be surprised by how simple it is.
Your dermatologist will review your medical history, discuss any personal concerns, and ask whether you've noticed any new or changing spots. You'll change into a gown so your skin can be examined from head to toe, including areas that aren't regularly exposed to the sun.
Using a specialized handheld instrument called a dermatoscope, your provider will closely evaluate moles and other pigmented lesions that may not be fully visible to the naked eye. This noninvasive tool helps provide a more detailed mole assessment and guides decisions about whether a spot appears harmless or should be evaluated further.
If a lesion deserves a closer look, your dermatologist may recommend a biopsy. This doesn't necessarily mean the spot is cancerous. In many cases, it's simply the best way to make an accurate diagnosis and determine whether any treatment is needed.
Most appointments last around 15 minutes, and many patients leave feeling reassured knowing exactly what was found.
When to Get a Mole Checked
While many moles remain unchanged throughout life, there are certain situations that warrant an evaluation by a dermatologist.
Schedule an appointment if you notice:
A new mole appearing
A mole that changes in size, shape, or color
A spot that looks noticeably different from your other moles
A mole that itches, bleeds, or becomes irritated
A spot that doesn't heal
It's important to remember that not every changing spot is skin cancer, and some skin cancers don't cause any obvious symptoms. When something looks or feels different, it's worth having it examined by a dermatologist rather than trying to determine what it is on your own.
The ABCDE Signs
The ABCDE rule is a helpful way to recognize changes that may deserve a closer look by your dermatologist. It is not a way to diagnose skin cancer, and many harmless moles may meet one or more of these criteria.
A. Asymmetry
One half of the mole doesn't match the other.
B. Border
The edges appear irregular or uneven.
C. Color
The mole contains multiple shades of brown, black, tan, red, white, or blue rather than one consistent color.
D. Diameter
The spot is larger than about 6 millimeters (roughly the size of a pencil eraser), although smaller moles can also warrant evaluation.
E. Evolving
The mole changes in size, shape, color, or symptoms such as itching, bleeding, or tenderness over time.
These are common signs of skin cancer mole changes that dermatologists evaluate, but they don't tell the whole story. Some harmless moles may meet one of these criteria, while some skin cancers may not. If a spot looks different from your other moles or has changed in any way, it's worth having it examined by a dermatologist.
Who Should Be Getting Checked, and How Often?
Skin exams aren't just for people who have noticed a suspicious mole.
Regular screenings are especially important for individuals who have:
Fair skin or light colored eyes
A history of frequent sun exposure or blistering sunburns
Numerous moles
A personal or family history of skin cancer
Living in Louisiana also plays a role. With year round UV exposure, your skin experiences cumulative sun damage throughout every season, making regular skin evaluations an important part of preventive care.
Your dermatologist can recommend how often you should schedule an annual skin exam based on your personal risk factors.
What Happens if Something Looks Suspicious
If your dermatologist identifies a spot that needs further evaluation, the next step is often a small biopsy performed in the office. The sample is sent to pathology, and the results are typically available within several days.
If the biopsy confirms skin cancer, your dermatologist will discuss the most appropriate treatment based on the diagnosis and location.
For many common skin cancers, Mohs surgery offers the highest cure rates while preserving as much healthy tissue as possible. Other skin cancers may be treated with different surgical or nonsurgical approaches depending on the individual case.

The most important takeaway is that finding something suspicious doesn't automatically mean the worst. Many skin conditions are benign, and when treatment is needed, having an experienced dermatology team helps ensure the best possible outcome.
