Saturday - 26/07/2025 04:15

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 represents one of the most prevalent cancer types globally. Its onset can be subtle, often manifesting as a seemingly innocuous new mole or a minor skin alteration, easily overlooked. However, early detection significantly enhances the treatability of skin cancer. Therefore, understanding how to identify potentially cancerous spots is crucial. From new growths and unusual moles to persistent sores, prompt recognition is key to effective intervention. Here are expert-recommended strategies to assist you in identifying early indicators of skin cancer and determining when to seek medical advice.

Examining skin for early signs of cancer

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: Does one half of the mole differ from the other?
Border: Are the edges irregular, notched, or blurred?
Color: Does the mole contain multiple shades (brown, black, red)?
Diameter: Is the mole larger than 6mm (the size of a pencil eraser)?
Evolving: Has the mole changed in shape, color, or size?

Any mole exhibiting these signs warrants serious consideration. Consult a dermatologist for evaluation.

Non-Healing Sores: A Red Flag

Do you have skin sores or scabs that repeatedly heal and reappear, or persist without healing? This could indicate early-stage basal or squamous cell carcinoma. These sores often present as pink, red, or slightly scaly patches and may bleed or ooze. A sore lasting more than three weeks or recurring in the same location should not be ignored. Persistent wounds, particularly on the face, arms, or scalp, require medical examination, as they can be subtle indicators of skin cancer.

When Moles Cause Discomfort

Moles are typically painless and stable. However, a mole that begins to itch, becomes tender, bleeds, or develops a crust could signal skin cancer and requires careful attention. These symptoms often point to inflammation or structural changes in the skin, potentially indicating a more serious condition than a normal mole. If you observe such changes, seeking advice from a skin specialist is advisable.

New Skin Growths: Stay Vigilant

Skin cancers don’t always arise from pre-existing moles. They can also develop as new growths, such as a small lump, a shiny bump, or rough patches, particularly on sun-exposed areas. If you detect any unusual formations on your skin, consult a skin specialist promptly.

Pigment Spread: A Cause for Concern

If the color of a mole starts to shift or spread into the surrounding skin, or if the edges become indistinct, it could be a sign of melanoma. This type of irregular pigment dispersion suggests that the mole may be expanding deeper or wider, which is a serious concern. Regularly compare your moles over time and take photos if necessary to help detect changes that could indicate skin cancer. If you notice anything unusual, consult a dermatologist for evaluation as soon as possible.
