Skin cancer, one of the most common types, develops when skin cells grow uncontrollably.
While most skin cancers are highly treatable if detected early, recognising the first symptoms can be crucial for achieving an early diagnosis and effective treatment.
What Are the Early Symptoms of Skin Cancer?
The skin, the body’s largest organ, acts as a protective barrier against external factors. However, prolonged sun exposure, genetic predisposition, and other factors can increase the risk of developing skin cancer.
Knowing how to distinguish the early signs of skin cancer from other common skin conditions can be vital for timely action and appropriate treatment. Below, we explain the most frequent initial symptoms.
- Changes in Existing Moles or Spots: Moles are typical skin growths that are usually benign. However, if you notice a mole changing in size, shape, or colour or developing irregular borders, it could be a sign of melanoma, the most aggressive type of skin cancer.
The ABCDE Rule for Evaluating Moles:
- Asymmetry: One half of the mole does not match the other.
- Borders: Edges are uneven, blurred, or jagged.
- Colour: Colour variation, including shades of brown, black, red, white, or blue.
- Diameter: Larger than 6mm (about the size of a pencil eraser).
- Evolution: Changes in size, shape, colour, or texture over time.
- New Spots on the Skin: Pay attention to new spots or changes in existing ones. Spots that itch, hurt, bleed, or fail to heal could be a warning sign.
Types of Spots to Watch For:
- Scaly patches: Red or pink, rough to the touch, and may bleed easily (squamous cell carcinoma).
- Shiny, pearly bumps: Waxy or pearlescent, often on the face, ears, or neck (basal cell carcinoma).
- Dark or brown spots: Flat or slightly raised, which can appear anywhere (melanoma).
- Sores That Don’t Heal: Sores that persist for weeks or seem to heal only to reopen may indicate skin cancer.
- Unusual Lumps: Be alert to new lumps, especially firm, shiny, or flesh-coloured.
- Changes in Skin Texture: Thickening, darkening, or redness of the skin can also be warning signs.
Differences Between Skin Cancer and Other Common Skin Conditions
While the symptoms above may suggest skin cancer, other common skin conditions can appear similar. Here’s how to tell them apart:
- Acne: Red, inflamed bumps, typically on the face, chest, or back. Unlike skin cancer, acne involves blackheads, whiteheads, or cysts and rarely becomes serious if appropriately treated.
- Eczema: Dry, itchy red patches that improve with moisturisers or topical treatments.
- Psoriasis: Red, scaly patches, often on elbows, knees, or the scalp. This is a chronic autoimmune condition, not uncontrolled cell growth.
- Benign Moles: Symmetrical, with smooth borders and uniform colour. Unlike melanomas, they remain stable over time.
Melanoma: The Most Dangerous Skin Cancer and How to Spot It
Though less common, melanoma is the most dangerous due to its spreading ability. Early recognition is critical. Look for:
- Asymmetry
- Irregular borders
- Colour variation
- Diameter >6mm (though melanomas can be smaller).
Diagnosis and Treatment of Skin Cancer

Early diagnosis is key. If skin cancer is suspected, diagnostic steps include:
- Physical examination by a dermatologist.
- Dermoscopy: A magnified view of skin structures.
- Biopsy: Tissue sample analysis.
Treatment Options:
- Surgery: Removal of the tumour and surrounding healthy tissue.
- Radiotherapy: High-energy rays to destroy cancer cells.
- Topical Treatments: Creams for early-stage cancers.
- Systemic Therapy: Immunotherapy or targeted treatments for advanced cases.
Factors Influencing Skin Cancer Risk

Uncontrollable Factors:
- Family history
- Fair skin, freckles, or red/blonde hair
- Numerous or atypical moles
- Age
Controllable Factors:
- Sun exposure (UV radiation)
- Avoidance of tanning beds
- Immune system health
Tips to Protect Your Skin:
- Seek shade between 10 a.m. and 4 p.m.
- Wear protective clothing, hats, and UV-blocking sunglasses.
- Use broad-spectrum SPF 30+ sunscreen, reapplied every 2 hours.
- Avoid tanning beds—opt for self-tanners instead.
- Check your skin monthly for new/changing moles or non-healing sores.
If you notice any concerning symptoms, consult a dermatologist promptly. Prevention and early detection save lives.
