If you read last month's post on hyperpigmentation, you already know the theme: Atlanta's UV index runs high for most of the year, and your skin keeps a record of every season spent outdoors. That same sun exposure is also the leading risk factor for skin cancer and Georgia consistently sees higher skin cancer rates than cooler, less sun-intensive states.
The good news is that skin cancer, when caught early, is one of the most treatable forms of cancer there is. That's the entire purpose of a skin cancer screening is catching something suspicious months or years before it becomes a more serious problem. In this post, I want to walk you through what a screening actually involves, what I'm looking for, and when you should come in.
Dr. Barnett's summer rule: If a spot is new, changing, bleeding, not healing, or simply looks different from your other moles, it deserves professional evaluation. You do not have to diagnose it yourself, that is what a skin cancer screening is for.
Why Atlanta Summers Make Skin Checks Essential
Georgia's climate creates the perfect conditions for cumulative sun exposure. Long warm seasons mean more months of outdoor activity, and high humidity can make people underestimate how much sun exposure they are getting, especially on cloudy or hazy days.
Even when the skin does not burn, ultraviolet radiation can still contribute to DNA damage, premature aging, precancerous lesions, and skin cancers over time. That is why prevention and screening go together. Sunscreen helps reduce risk, but screening helps identify problems that have already started to develop.
- More skin is exposed during pool days, beach trips, sports, and outdoor exercise
- People notice spots more easily when wearing summer clothing
- Sunburn history matters, especially blistering burns or repeated childhood burns
- UV exposure is cumulative, meaning damage builds over months and years
- Early evaluation can prevent delays when a spot needs biopsy or treatment
The ABCDE Rule: Warning Signs You Should Never Ignore
The ABCDE rule is a helpful way to remember some of the most common warning signs of melanoma. It is not a substitute for a professional skin exam, but it can help patients know when to schedule an appointment sooner rather than later.
Asymmetry
One half of the mole or spot does not match the other half.
Border
The edges look irregular, blurred, ragged, or poorly defined.
Color
The color is uneven or includes different shades of brown, black, red, white, or blue.
Diameter
The spot is larger than about 6 millimeters, though concerning spots can also be smaller.
Evolving
The spot is changing in size, shape, color, texture, or symptoms.
Did you know? Roughly one in five Americans will develop some form of skin cancer by age 70. Melanoma, the most dangerous type, is also one of the most curable cancers when it's caught at an early stage, which is exactly why annual screening matters.
Dr. Barnett's Skin Cancer Screening & Treatment Approach
A thorough screening is simple, quick, and genuinely one of the highest-value visits you can make to a dermatologist. Here's what I recommend and how I approach it for my Atlanta patients.
1. The Annual Full-Body Skin Exam
For most adults, I recommend a full-body skin exam once a year and more often if you have a personal or family history of skin cancer, a high mole count, or significant sun exposure history. I examine the skin from scalp to soles, including areas patients often forget to check themselves, like the back, scalp, and between the toes.
2. Dermoscopy for a Closer Look
When I find a mole or lesion that needs a closer look, I use dermoscopy, a handheld magnification tool that lets me examine pigment patterns and structures beneath the skin's surface that aren't visible to the naked eye. It helps me decide, often in real time, whether something needs to be biopsied or simply monitored.
3. When a Biopsy Is Needed
If a lesion looks suspicious, the next step is a skin biopsy — a quick, in-office procedure done under local anesthesia. Depending on the lesion, I'll use a shave, punch, or excisional technique to remove some or all of it for evaluation by a dermatopathology lab. Most biopsies take just a few minutes, and results typically come back within a week to ten days.
4. Treatment Options If Skin Cancer Is Found
If a biopsy comes back positive, treatment depends on the type, size, and location of the cancer. Here's an overview of the most common approaches:
Excisional Surgery
Surgical removal of the cancer with a margin of healthy tissue. The standard treatment for most basal cell and squamous cell carcinomas.
In-office · local anesthesiaMohs Micrographic Surgery
For skin cancers on the face or in cosmetically sensitive areas, I refer patients to a fellowship-trained Mohs surgeon I trust, for the highest cure rate with minimal scarring.
Referral · same-week schedulingTopical Chemotherapy
Prescription creams for certain superficial basal cell carcinomas and precancerous lesions, applied at home over several weeks.
At-home · several weeksCryotherapy
Freezing precancerous lesions (actinic keratoses) with liquid nitrogen before they have a chance to progress.
