5 Warning Signs of Skin Cancer Every Floridian Should Know

Living in Florida means year-round sunshine, beautiful beaches, and an outdoor lifestyle that many of us wouldn't trade for anything. But that same glorious sunshine that makes our state so desirable comes with a serious health consideration: Florida has one of the highest rates of skin cancer in the nation. In fact, melanoma rates in Florida are significantly higher than the national average, and non-melanoma skin cancers like basal cell carcinoma and squamous cell carcinoma are even more common. At Tampa Bay Dermatology, we've seen firsthand how crucial it is for Floridians to know what to look for on their skin.

The good news? Skin cancer is highly treatable when caught early. By knowing the warning signs and scheduling regular skin examinations, you can dramatically improve your outcomes. Here are the five warning signs every Floridian should know: what we in dermatology call the ABCDE method.

Why Floridians Face Higher Skin Cancer Risk

Before we dive into the warning signs, let's talk about why Florida specifically is a hotspot for skin cancer. First, there's the obvious: our geography. Florida sits at a lower latitude, meaning the sun's UV rays hit our skin more directly and intensely than they do in northern states. We also enjoy sunshine year-round, meaning we're not protected by winter months of reduced sun exposure like people in colder climates.

Beyond latitude, there's our lifestyle. Many of us spend hours outdoors: boating, fishing, golfing, beach trips with our families. That's wonderful for our quality of life, but it's also wonderful for UV exposure. And then there's our demographics: Florida attracts retirees who spend decades soaking up the Florida sun. Cumulative sun exposure is one of the most significant risk factors for melanoma and other skin cancers, so residents who've lived here for decades face considerably higher risk.

The ABCDE Method: 5 Warning Signs to Watch For

The ABCDE method is your best tool for early detection. Think of these five letters as a self-screening checklist. If you notice any of these characteristics on a mole or suspicious spot, schedule an appointment with a dermatologist right away.

A: Asymmetry

A normal, benign mole is typically symmetrical. If you draw an imaginary line through the middle, both halves should look similar. If one half doesn't match the other (if the mole looks lopsided or unbalanced), that's a red flag. This asymmetry is one of the earliest warning signs of melanoma that dermatologists look for in practice.

B: Border Irregularity

Benign moles have clean, well-defined borders. If a mole has a jagged, notched, or scalloped border that looks irregular or blurred, it's worth getting checked. Normal moles look like they've been carefully drawn with a pen; cancerous moles often look like they've been sketched by someone who couldn't quite stay within the lines.

C: Color Variation

Most benign moles are one consistent color (usually brown or tan). If a mole contains multiple colors, that's concerning. Look for shades of brown, black, tan, red, white, or blue within the same spot. The presence of several colors, especially red or blue, should prompt you to schedule a skin cancer screening with our dermatology team.

D: Diameter

Any mole larger than the size of a pencil eraser (generally about 6 millimeters or larger) should be evaluated. While not all large moles are cancerous, size is an important factor in melanoma risk. When examining patients at Tampa Bay Dermatology, we pay special attention to larger lesions, and we encourage our patients to do the same during their monthly self-exams.

E: Evolving (Changing)

This might be the most important warning sign of all. Any mole or spot that's changing in size, shape, color, or appearance should be examined by a dermatologist. This includes moles that are becoming itchy, tender, or bleeding. Our skin naturally changes over time, but a mole that's evolving is raising a red flag. We always tell our Florida patients: if you notice a spot changing, don't wait. Call our office.

Other Warning Signs to Watch For

While the ABCDE method covers melanoma, there are other signs that warrant professional evaluation:

• A sore that doesn't heal or keeps returning
• A spot that bleeds, oozes, or becomes tender without injury
• A waxy, scaly bump that resembles a wart or mole but grows slowly
• A patch of skin that becomes rough, dry, or scaly
• A new spot appearing on sun-exposed areas

When to See a Dermatologist

If you're a Floridian, regular professional skin examinations should be part of your health routine. We recommend that patients with fair skin or a family history of skin cancer come in annually for a full-body skin exam. Those with darker skin tones and lower risk profiles might need screening less frequently, but everyone should become familiar with their own skin and watch for changes.

Don't wait for symptoms or obvious changes. Many skin cancers are caught during routine screening before patients even notice anything wrong. And if you do spot something concerning (anything that fits the ABCDE criteria or any lesion that seems to be evolving), schedule an appointment promptly. Early detection literally saves lives.

One of the benefits of working with a board-certified dermatologist is that we can use tools like dermoscopy and, if needed, biopsy to make accurate diagnoses. We're trained to spot the subtle signs that you might miss, and we know which spots truly need attention and which are benign. After performing thousands of skin exams across the Tampa Bay area, our team can tell you: catching skin cancer early transforms outcomes.

Protect Yourself While You're Still in the Sun

Of course, knowing the warning signs is just half the battle. The other half is preventing skin cancer in the first place. This means wearing broad-spectrum SPF 30 or higher sunscreen every single day (yes, even on cloudy days, and even if you're just running errands). For more detailed guidance, check out our sun protection tips for Tampa residents. It means seeking shade during peak sun hours (10 AM to 4 PM), wearing protective clothing, and considering UV-protective swimwear if you spend significant time in the water.

Sunscreen isn't negotiable in Florida. Neither are regular skin checks.

Take Action Today

If you've read through the ABCDE method and realized you haven't had a professional skin examination in the past year, it's time to schedule one. If you've spotted something on your skin that concerns you, don't delay. Early detection saves lives, and treatment is far more successful when skin cancer is caught at an early stage.
