Thursday - 26/06/2025 09:25

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 form of cancer worldwide, often manifesting initially as a subtle change, such as a new mole or a minor alteration to the skin. These early signs can easily be overlooked. However, early detection is crucial, as skin cancer is highly treatable in its initial stages. Recognizing potentially cancerous spots is therefore essential.

The following expert-backed tips will guide you in identifying the early signs of skin cancer and determining when to seek medical advice.

The ABCDE Rule for Mole Assessment

The ABCDE method is a valuable tool for detecting melanoma, a serious type of skin cancer. This acronym stands for:

Asymmetry: One half of the mole does not match the other, indicating an irregular shape.
Border: The mole has irregular, notched, or blurred edges.
Color: The mole exhibits multiple shades of brown, black, or red.
Diameter: The mole's size exceeds 6mm (the size of a pencil eraser).
Evolving: The mole demonstrates changes in shape, color, or size.

If a mole displays any of these characteristics, it warrants serious attention and a consultation with a dermatologist.

Non-Healing Sores: A Potential Warning Sign

Persistent skin sores or scabs that repeatedly heal and reappear, or sores that fail to heal completely, 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.

A sore that persists for more than three weeks or recurs in the same location should not be ignored. Such persistent wounds, especially on the face, arms, or scalp, require medical evaluation as they could be a subtle sign of skin cancer.

Itchy, Painful, or Bleeding Moles

Moles should typically be painless and stable. A mole that begins to itch, becomes tender, bleeds, or develops a crust could be a sign of skin cancer and requires prompt evaluation. These symptoms often suggest inflammation or structural changes in the skin that could signal a more serious issue than a normal mole. Consulting a skin specialist is advisable if you observe any of these changes.

Moles that cause discomfort and could indicate skin cancer

New Moles, Growths, or Bumps

Skin cancers do not always originate from existing moles. They can also develop from new growths, such as a small lump, a shiny bump, or rough patches, particularly on areas exposed to the sun. Any new or unusual growths should be examined by a skin specialist.

Pigment Spread Beyond a Mole

If the color of a mole suddenly changes or spreads to the surrounding skin, or if the mole has fading edges, it could indicate melanoma. This irregular pigment spread suggests that the mole may be growing deeper or wider, requiring immediate attention. Regular self-examinations and photographs of your moles can help you detect any changes that might point toward skin cancer. Consult a dermatologist for prompt evaluation if you observe any concerning changes.
