Skin Cancer Alert: How to Identify Suspicious Moles and Early Warning Signs

Thursday - 26/06/2025 09:45

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's prevalence worldwide often begins subtly, perhaps as an overlooked new mole or minor skin change. However, early detection dramatically improves treatment outcomes. Recognizing potentially cancerous spots is therefore crucial. New growths, unusual moles, or persistent sores all warrant attention. Here's expert advice on identifying early signs of skin cancer and knowing when to seek medical advice.

Understanding the first signs of skin cancer

The ABCDE Rule for Mole Assessment

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 exhibits multiple shades (brown, black, red).
Diameter: The mole is larger than 6mm (pencil eraser size).
Evolving: The mole shows changes in shape, colour, or size.

Any mole displaying these signs requires prompt evaluation by a dermatologist.

Non-Healing Sores: A Potential Warning Sign

Persistent skin sores or scabs that repeatedly heal and reappear, or simply refuse to heal, can indicate basal or squamous cell carcinoma. These sores often manifest as pink, red, or slightly scaly patches and may bleed or ooze. A sore lasting longer than three weeks or recurring in the same location shouldn't be ignored. Particularly on the face, arms, or scalp, these persistent wounds demand medical examination, as they could be a subtle indicator of skin cancer.

Examining sores that won't heal for possible cancer signs

Itchy, Painful, or Bleeding Moles: Take Note

Typically, moles are painless and stable. However, a mole that begins to itch, becomes tender, bleeds, or develops a crust warrants serious attention, as it could signal skin cancer. These symptoms often point to inflammation or structural skin changes, potentially indicating a more serious issue than a normal mole. Consulting a skin specialist is always advisable when such changes occur.

New Moles, Growths, or Bumps: Stay Vigilant

Skin cancers don't always arise from existing moles. They can also develop from new growths, such as small lumps, shiny bumps, or rough patches, particularly in sun-exposed areas. Prompt consultation with a skin specialist is crucial for evaluating any such new developments.

Pigment Spreading: A Cause for Concern

If the color of a mole abruptly changes or spreads into the surrounding skin, or if the mole develops fading edges, it could be a sign of melanoma. This irregular pigment spread suggests the mole may be growing deeper or wider, necessitating serious consideration. Regular mole comparison over time, aided by photos, can help detect changes indicative of skin cancer. Dermatological evaluation is recommended if such changes are observed.
