Thursday - 26/06/2025 09:30

Skin cancer is one of the most common type of cancer across the world, and it often starts with something as subtle as a new mole or a small change in your skin-- which often go unnoticed. However, if detected early, skin cancer is highly treatable. That’s why learning how to recognise suspicious spots that can possibly be due to skin cancer is important. Whether it's a new growth, an unusual mole, or a sore that doesn’t heal, early detection is key to treating skin cancer. Here wee list some expert-backed tips to help you spot the early signs of skin cancer and know when it’s time to see a doctor:

Skin cancer is a prevalent global concern, often manifesting subtly through new moles or minor skin alterations that can easily go unnoticed. Early detection is paramount, as it significantly improves the chances of successful treatment. Recognizing potentially cancerous spots is a crucial skill. Be alert for new growths, unusual moles, or persistent sores. Here's a guide to help you identify early signs of skin cancer and understand when to seek professional medical advice.

The ABCDEs of Mole Monitoring

The ABCDE method is a valuable tool for detecting melanoma, a serious form of skin cancer. Each letter represents a characteristic to watch for:

Asymmetry: One half of the mole doesn't match the other.
Border: The mole has irregular, notched, or blurred edges.
Colour: The mole displays multiple shades of brown, black, or red.
Diameter: The mole is larger than 6mm (about the size of a pencil eraser).
Evolving: The mole changes in shape, color, or size.

Any mole exhibiting these features warrants immediate evaluation by a dermatologist.

Non-Healing Sores: A Red Flag

Persistent skin sores or scabs that repeatedly heal and reappear, or sores that simply refuse to heal, can be an early indicator of basal or squamous cell carcinoma. These sores often present as pink, red, or slightly scaly patches and may bleed or ooze. It's crucial to consult a doctor if a sore persists for more than three weeks or recurs in the same location. Pay particular attention to wounds or sores on the face, arms, or scalp, as these could be subtle signs of skin cancer.

When Moles Become Problematic

Moles are typically painless and stable. However, a mole that begins to itch, becomes tender, bleeds, or develops a crust should be carefully examined. These symptoms can indicate inflammation or structural changes within the skin, potentially signaling a more serious issue than a typical mole. Consulting a skin specialist is always advisable when such changes occur.

Identifying problematic changes in existing moles

New Growths: Not Always Benign

Skin cancers can arise from new growths rather than existing moles. Be vigilant for small lumps, shiny bumps, or rough patches on the skin, especially in sun-exposed areas. Prompt evaluation by a skin specialist is crucial if you observe any such new formations.

Pigment Spread: A Cause for Concern

If the color of a mole unexpectedly changes or spreads to the surrounding skin, or if the mole develops fading edges, it could be a sign of melanoma. This irregular pigment spread suggests potential growth deeper or wider, requiring immediate attention. Regularly compare your moles over time, and consider taking photos to track any changes that might indicate skin cancer. Dermatological consultation is essential if you notice similar symptoms.
