When people in South Florida think about melanoma, they usually picture the same thing: a flat, discolored mole with uneven edges that gradually changes over months. That mental image comes from years of public health campaigns, and it's not wrong — it just doesn't describe every type of melanoma. Nodular melanoma is the one that tends to catch people completely off guard.
It doesn't look like what patients expect. It often doesn't follow the rules they've been taught. And in a region where people are outdoors year-round and sun exposure is essentially unavoidable, that gap between expectation and reality has real consequences for the nodular melanoma survival rate.
Most melanomas grow outward across the surface of the skin before they grow downward into deeper tissue. That horizontal phase is what gives people time to notice changes — a spot that's spreading, shifting color, or developing an irregular border. Nodular melanoma skips that phase almost entirely.
Instead, it grows vertically from the start, pushing down into the skin rapidly. That's what makes it the most aggressive subtype of melanoma. By the time it's large enough to be visually obvious, it may already be in deeper layers of tissue — and the nodular melanoma survival rate drops sharply with depth.
The survival rate for melanoma caught at stage 1, while it's still thin and localized, is over 98%. Once it spreads to distant organs, that number falls below 30%. The difference between those outcomes is often just a matter of months — sometimes less — which is why understanding the signs before a lesion becomes unmistakable is so important.
This is where patients — and even some non-specialist providers — get tripped up. Nodular melanoma frequently presents as:
That last point is worth pausing on. Amelanotic melanoma lacks the dark pigment most people associate with skin cancer. It can appear skin-toned, pinkish, or slightly reddish — and it is frequently dismissed as a cyst, a pimple, or an insect bite. By the time it's biopsied, it may already be well-advanced.
The signs melanoma has spread go beyond what you can see on the surface. Swollen lymph nodes near the lesion — particularly in the neck, armpit, or groin — unexplained fatigue, and changes in nearby skin can all indicate regional spread. These are symptoms that deserve immediate attention, not a wait-and-see approach.
One of the most dangerous locations for nodular melanoma in South Florida is somewhere most patients never think to check: the scalp.
The warning signs of stage 1 melanoma on the scalp are almost impossible to see without parting the hair carefully — or without a trained clinician doing a thorough skin check. Hair covers the lesion. Patients often don't feel it until it's raised enough to notice while washing their hair. And because the scalp has a rich blood and lymph supply, melanomas in this location have a faster route to spread.
South Florida makes this worse. Outdoor lifestyles mean constant sun exposure on the top of the head. Caps and hats help, but most people wear them inconsistently. And the idea that "I'd notice something growing on my head" is a comfortable assumption that doesn't hold up clinically — especially for patients with thicker or longer hair.
If you haven't had your scalp examined as part of a skin check, it's worth specifically asking for one. A full-body skin check should mean exactly that — including the scalp, ears, and back of the neck. Scalp sunburn is more dangerous than most people assume, and the same is true for the melanomas that can develop from cumulative damage in that area.
Florida has one of the highest melanoma incidence rates in the country. That's not a coincidence — it reflects decades of intense UV exposure in a state where outdoor activity is a way of life, not just a weekend hobby. When you factor in South Florida's specific demographics — year-round sunshine, high rates of boating and fishing, an aging population, and a significant snowbird community that may have spent decades accumulating sun damage — the risk profile becomes serious.
South Florida's boating and fishing culture puts your skin at serious risk for melanoma, and that's especially true for nodular melanoma because the cumulative, intense UV exposure that comes with time on the water accelerates the kind of DNA damage that leads to aggressive lesions.
Tanned skin, dark complexions, and spray tans can also obscure changes that would otherwise be visible. Self-tanners can hide dangerous skin changes that a dermatologist needs to catch — and nodular melanoma, especially in its early stages, is exactly the kind of change that gets buried under color.
Fast enough that waiting for a scheduled annual check isn't always sufficient if you notice something new.
Most melanomas take years to develop to a dangerous depth. Nodular melanoma can reach a clinically concerning thickness in weeks to months. Research has documented cases where a lesion went from imperceptible to millimeters deep in under three months. That timeline changes the math on "I'll get it looked at soon."
If you notice a new raised bump that wasn't there before — regardless of what color it is — that warrants a prompt dermatology evaluation. Not because it's definitely cancer, but because the cost of being wrong is too high to treat it casually.
At Dermatology Experts, a suspicious lesion gets a thorough look before any decisions are made. Dr. Ayar will examine the lesion visually, often using dermoscopy — a handheld tool that essentially lets him see beneath the skin's surface without cutting into it first. That evaluation determines whether a biopsy is warranted.
If a biopsy is needed, it's a straightforward in-office procedure. A small sample of tissue is removed and sent to a lab for analysis. The results tell us whether it's melanoma, what subtype, and how deep it is — all of which shape the next steps. Body mapping technology helps catch skin changes patients miss, and combined with a trained clinical eye, it significantly improves the odds of catching something early.
If nodular melanoma is confirmed, treatment typically involves surgical excision with margins — meaning a specific amount of surrounding tissue is removed along with the tumor. Depending on the stage, additional treatments such as sentinel lymph node biopsy, immunotherapy, or targeted therapy may be discussed. Dr. Ayar will walk patients through every step clearly, without the runaround, because that's what people deserve when they're navigating something this serious.
With nodular melanoma, the goal isn't just catching it early — it's making sure it gets caught at all. That requires a professional skin check from someone who knows what they're looking for.
Mole mapping technology is changing early detection in South Florida, and for patients with a history of significant sun exposure, multiple moles, or a personal or family history of skin cancer, it's one of the most practical tools available for staying ahead of something like nodular melanoma.
Annual skin checks are a baseline recommendation. If you have elevated risk factors — fair skin, history of sunburns, outdoor occupation, immunosuppression, or a family history of melanoma — more frequent checks may make sense. The conversation about how often is one worth having with Dr. Ayar directly.
South Florida's sun makes year-round skin cancer screenings essential — not just a once-a-year formality. The patients who do best with melanoma are the ones who treat their skin checks the same way they treat dental cleanings: a regular part of life, not something that happens only when something feels wrong.
The most important thing to understand about nodular melanoma is that it may never look like what you've been told to watch for. A raised bump that seems too small to worry about. A pinkish spot that looks irritated. Something you've been half-noticing for a few weeks and planning to mention "at your next appointment."
These are the lesions that benefit most from being seen promptly.
Dermatology Experts has three locations in Miami, Parkland, and Tamarac — which means a skin check is accessible no matter where you are in Miami-Dade, Broward, or Palm Beach County. If something on your skin is new, growing, or just not sitting right with you, that's reason enough to come in. You don't need to wait until you're sure. That's what we're here for.
Call Dermatology Experts to schedule a full-body skin check with Dr. Ayar. Early is always better — especially with this one.
