Melanoma
A serious form of skin cancer that develops from pigment-producing cells, often appearing as a new or changing mole. Caught early it is usually treatable, so prompt medical assessment of any suspicious mole is essential.
⚠ Seek medical attention if:
A mole that is asymmetrical, has an irregular border, uneven colour, is larger than about 6 mm, or is changing, itching, or bleeding (the ABCDE signs). Any new or changing mole needs prompt assessment. See a doctor urgently.
Lifestyle factors
Excess ultraviolet (UV) exposure from the sun or sunbeds, sunburn (especially in childhood), and having fair skin, many moles, or a family history increase risk; sun protection lowers risk
Nutritional factors
No supplement or diet treats or reliably prevents melanoma; a healthy diet supports general health, and sun protection is the key preventive measure
Possible medical causes
DNA damage to pigment cells, largely from UV exposure; genetic factors, fair skin, and a history of many moles or previous skin cancer increase risk
Next steps
See a GP or dermatologist urgently for any suspicious or changing mole. Melanoma is diagnosed and treated medically, and early detection greatly improves outcomes. This is not a condition to self-manage.
