Melanoma is a malignant tumour arising from melanocytes — the pigment-producing cells of the skin — and represents the most aggressive form of skin cancer. When detected at an early stage, treatment success rates exceed ninety percent; in advanced stages, however, survival rates drop dramatically. Awareness of risk factors and recognition of early warning signs is therefore of critical importance.
Melanoma Risk Factors
Genetics and Family History
Individuals with a first-degree relative diagnosed with melanoma face a two- to three-fold increase in risk. Mutations in genes such as CDKN2A and CDK4 have been linked to familial melanoma syndromes. People with a hereditary predisposition are advised to undergo dermatological check-ups more frequently.
Skin Tone and Phenotypic Features
Fair skin, light-coloured eyes, red or blonde hair, and a tendency to freckle significantly elevate melanoma risk. Individuals classified as Fitzpatrick skin type I or II represent the highest-risk group.
Sun Exposure and History of Sunburn
Severe sunburns — particularly those occurring during childhood and adolescence — substantially increase the likelihood of melanoma developing in later years. Intermittent intense UV exposure is considered more hazardous than chronic low-level exposure. The use of tanning beds is also recognised as an independent risk factor.
Number of Moles and Atypical Moles
Individuals with fifty or more melanocytic naevi on their body carry an elevated melanoma risk. In the condition known as dysplastic (atypical) naevus syndrome, numerous irregularly structured moles are present, and the lifetime probability of melanoma developing in these individuals is high.
Immunosuppression
Patients receiving immunosuppressive therapy following organ transplantation, HIV-positive individuals, and those whose immune system is suppressed due to autoimmune conditions face a significantly higher melanoma risk compared with the general population.
Early Warning Signs
Early signs of melanoma most commonly present as changes in an existing mole or as newly appearing pigmented lesions on the skin. The principal warning signals to watch for are:
- Rapid growth: A mole or lesion that enlarges noticeably within a matter of weeks or months.
- Colour heterogeneity: Multiple shades of colour visible within a single lesion.
- Irregular borders: Lesion margins that become rough, notched, or poorly defined.
- Itching and tenderness: The onset of itching, burning, or pain in a mole that was previously symptom-free.
- Bleeding or ulceration: A lesion that bleeds spontaneously without trauma, or a wound that fails to heal.
- Satellite lesions: The appearance of new small pigmented spots around the primary lesion.
Prevention and Early Detection Recommendations
Regular use of sunscreen, physical barriers, and avoidance of peak sun hours are the fundamental prevention strategies. Individuals in high-risk groups are advised to have a dermatological examination every six months; all other individuals should do so at least once a year.
