What are the warning signs that a mole can be cancerous?
Most moles are normal and harmless, but some can change in ways that signal a problem. Paying attention to these changes can help catch skin cancer early.
A mole may need medical attention if you notice that it:
- Starts growing or becomes noticeably larger than before
- Changes its outline, especially if the edges look rough, uneven, or blurred
- Shifts in colour, becomes darker, or develops more than one colour
- Looks uneven, means one side doesn't match the other
- Feels uncomfortable, such as itching, tenderness, pain, or bleeding
- Forms a scab, becomes crusty, or shows signs of swelling
- Displays several shades of brown, black, or other colours
- Rises above the skin or becomes thicker when it used to be flat
A good rule to remember is: if a mole looks different from your other moles or starts behaving differently, it's worth checking. Early assessment by a healthcare professional can make treatment simpler and more effective.
