Most Australians have heard of melanoma, but far fewer know about its most aggressive subtype — nodular melanoma. Unlike the classic slow-growing moles that gradually change shape and colour, nodular melanoma can develop and spread within weeks. It does not follow the usual warning signs, which is exactly why it is so often caught late. Understanding what makes this cancer different could genuinely save your life.
What Is Nodular Melanoma?
Nodular melanoma is a subtype of melanoma that grows vertically into the deeper layers of the skin rather than spreading outward across the surface. This invasive growth pattern is what makes it so dangerous. While other forms of melanoma tend to show gradual changes over months or even years, nodular melanoma can reach a life-threatening depth in a matter of weeks.
It accounts for roughly 15% of all melanoma diagnoses in Australia but is responsible for a disproportionately high number of melanoma deaths. The reason is straightforward — by the time most people notice it, the cancer has already penetrated deep into the skin and may be on the verge of spreading to other parts of the body.
Why It Is So Easy to Miss
It Does Not Look Like a Typical Melanoma
Most people are taught to look for asymmetrical, multicoloured moles with irregular borders. This is the ABCDE rule — Asymmetry, Border, Colour, Diameter, and Evolution. Nodular melanoma breaks almost all of these rules. It often appears as a small, round, raised lump that looks symmetrical, has defined borders, and may be a single uniform colour — sometimes pink, red, or even skin-toned rather than the expected dark brown or black. This presentation is sometimes referred to as amelanotic melanoma, a hidden threat many people fail to recognise.
This means many people dismiss it as a harmless cyst, pimple, or insect bite. It does not look threatening, and so they wait. That waiting period is where the real danger lies.
It Grows Fast
One of the defining characteristics of nodular melanoma is the speed of its growth. A lesion that did not exist three months ago, or was barely noticeable six weeks ago, can become significantly elevated and deeply invasive within a short period. Any new lump or growth that appears suddenly and continues to grow — regardless of its colour or shape — should be assessed by a doctor without delay.
Who Is Most at Risk?
Nodular melanoma can affect anyone, but certain factors increase the likelihood of developing it:
- Age — it is most commonly diagnosed in people over 50, though it can occur at any age
- Fair skin, light eyes, or red/blonde hair — these traits reduce natural UV protection
- History of sunburn — particularly severe or blistering sunburns earlier in life
- High lifetime UV exposure — especially relevant for Queenslanders who spend significant time outdoors
- Family history of melanoma — a first-degree relative with melanoma increases your personal risk
- Weakened immune system — whether from illness, medication, or organ transplantation
- Large number of moles or atypical moles — more moles means more opportunities for abnormal cell changes
Living in Queensland already places you in one of the highest UV exposure zones in the world, which makes awareness and early detection even more critical for the local community.
How Nodular Melanoma Is Diagnosed?
What to Look For
Because nodular melanoma does not follow the classic ABCDE warning signs, doctors have introduced an additional acronym specifically for this subtype: EFG — Elevated, Firm to touch, and Growing. Any lump on the skin that is raised above the surface, feels firm when pressed, and has been visibly growing over recent weeks warrants an urgent skin assessment.
The Importance of a Professional Skin Check
Self-examination has limits. It is difficult to accurately assess a lesion on your own back, scalp, or behind the ears — areas where nodular melanoma is known to develop. A professional skin check using dermoscopy allows a trained doctor to examine the structure of a lesion beneath the surface, picking up features that are entirely invisible to the naked eye.
If a suspicious lesion is identified, a biopsy is taken and sent for laboratory analysis to confirm the diagnosis. Early detection at this stage, before the cancer spreads, dramatically improves treatment outcomes.
Treatment Options
When nodular melanoma is caught at an early stage, treatment typically involves surgical excision — removing the tumour along with a margin of surrounding healthy tissue. The prognosis at this stage is generally very good. However, when the cancer is detected at a more advanced stage, treatment becomes considerably more complex and may involve:
- Wider surgical excision
- Sentinel lymph node biopsy to check for spread
- Immunotherapy or targeted drug therapy
- Radiation therapy in some cases
This is why the timing of diagnosis matters so much. A nodular melanoma caught at 1mm depth has a very different outlook compared to one that has reached 4mm or beyond.

When Should You See a Doctor?
Do not wait for a lesion to look ‘bad enough.’ Book an appointment at our skin cancer clinic Ipswich if you notice:
- A new lump or growth that has appeared within the last few weeks
- Any existing spot that has changed in size, shape, or texture
- A raised, firm bump that is growing — regardless of its colour
- A sore that bleeds easily or does not heal within a few weeks
- Any skin change that simply does not feel right to you
Your instincts about your own skin matter. When in doubt, get it checked.
