Skin cancer is one of the most common types of cancer in the UK and across the globe, but it’s also one of the most treatable if caught early enough – which is why it’s important to know the signs.
It typically develops on skin areas most exposed to the sun, emphasising the importance of checking your skin for any unusual changes after prolonged outdoor exposure.
The quickest route to diagnosis is self-detection of symptoms, making it crucial to understand what skin cancer may look like.
However, identifying these changes can be challenging if you’re unsure what to look out for.
Cadogan Clinic consultant dermatologist Dr Susan Mayou highlighted some of the potentially cancerous indicators that can be spotted on the face.
Asymmetry
The dermatologist noted this could be a primary sign of skin cancer.
She said: “This is when one half of the spot doesn’t match the other half.”
Misshapen borders
A skin spot showcasing uneven borders is another potential indicator of skin cancer.
Dr Mayou told The Sun: “Borders that are irregular, scalloped or poorly defined are another concern.”
Size
A spot larger than 6 mm in diameter could be another sign of skin cancer.
The expert added: “If the spot is larger than 6mm in diameter or shows changes in size, shape, colour or elevation over time, it may be cause for concern.”
Colour changes
Dr Mayou advised patients should seek medical advice if they notice a spot on their face experiencing colour variations.
She said: “A spot with multiple hues or uneven pigmentation can also be a red flag.”
Bleeding
Losing blood from a spot on the face is one of the clearest signs something is wrong.
Dr Mayou added: “If the spot starts to bleed, ooze or causes itching or pain, these are important symptoms to note.”
