Squamous cell carcinoma can appear in different ways, which is why it's important to pay attention to any unusual skin changes.

It often starts as a skin-coloured or light red lump or patch with a rough or scaly surface. Some SCCs may look like a wart-like growth, while others can resemble a sore or bruise that doesn't heal. These spots may develop raised edges and can crust, scab, or bleed.

SCC usually grows slowly, but if left untreated, it can become larger and may form an open sore or ulcer in the centre.

Any skin lesion that continues to change, bleed, or fail to heal should be checked by a medical professional, as early detection greatly improves treatment outcomes.
