What is Melanoma?
Malignant Melanoma is a type of cancer that develops from melanocytes, the pigment-producing cells in your skin that give you your tan or natural skin tone. While it is less common than Basal Cell Carcinoma (BCC) or Squamous Cell Carcinoma (SCC), melanoma is significantly more dangerous because of its ability to spread (metastatic melanoma) to other organs like the lungs, brain, and liver if not treated early.
The primary driver of this disease is DNA damage to skin cells, most often caused by exposure to Ultraviolet (UV) radiation from the Australian sun or tanning beds. This damage triggers mutations that lead the skin cells to multiply rapidly and form malignant tumors.
In 2025, our understanding of melanoma has evolved. It is no longer just about “cutting it out”; it involves understanding genetic markers like the BRAF V600E mutation and utilizing advanced dermoscopy for earlier detection than ever before.
Key Takeaway: You can have melanoma for years without knowing, or it can appear suddenly. Vigilance is your best defense.
The "Ugly Duckling" Sign & Nodular Melanoma
Not all melanomas follow the ABCDE rule. This is particularly true for Nodular Melanoma, an aggressive form that accounts for about 15% of cases but a large percentage of melanoma deaths.
The Ugly Duckling Sign
Most of your moles typically look like each other (your “signature” mole type). An “Ugly Duckling” is a lesion that stands out because it looks completely different from your other moles. If you have one spot that doesn’t fit the pattern, it needs to be checked immediately via dermoscopy.
Nodular Melanoma: The Exception to the Rule
Nodular melanoma grows down into the skin (vertical growth) rather than across the surface. It is firm to the touch and typically presents with the EFG symptoms:
Elevated: Raised above the skin surface.
Firm: Feels hard to the touch (like a BB pellet under the skin).
Growing: Grows rapidly (over weeks).
Is melanoma usually itchy or painful? While many are painless, nodular melanomas may feel tender or itchy. Never ignore a firm, growing lump on the skin, even if it is pink or skin-colored (amelanotic melanoma).
Diagnosis at Sun Smile Clinic: Dermoscopy & Biopsy
At Sun Smile Clinic, we don’t just “look” at your skin; we analyze it using advanced medical technology.
1. Full Body Skin Check & Dermoscopy
We utilize high-resolution dermoscopy. A dermatoscope is a specialized handheld microscope that allows our doctors to see structures below the skin’s surface that are invisible to the naked eye. This allows us to detect Melanoma In Situ (Stage 0) long before it becomes invasive.
2. Biopsy Procedures
If a suspicious lesion is found, a biopsy is the only way to confirm a diagnosis.
