How is melanoma diagnosed?

A diagnosis of melanoma begins with an examination of your skin

Our skin check leaflet can help you monitor your moles. Speak to your GP immediately if you notice any changes.

  • Initially you might be asked to take a picture of the area to send to your GP. This may be sent through a secure messaging system to a specialist dermatology team for review. This pathway is called Teledermatology.

  • Your GP or a specialist dermatologist may take digital photos of your mole or lesion. They may use a dermatoscope, a type of magnifying tool, to enable them to view deeper layers of your skin
  • If your GP has some concern that you may have melanoma, you may be referred for an urgent review. This does not mean you have a melanoma, it just means you will be reviewed urgently. 
  • If a skin lesion or mole appears suspicious, it may be removed, or alternatively a biopsy taken for further evaluation. This is usually done with a local anaesthetic, so you shouldn’t feel any pain.
  • If melanoma is confirmed, you may require further tests and treatment.
  • We’ve put together some frequently asked questions (FAQs) and useful tips to help you know what to expect if you have been diagnosed with melanoma. Click here to read more
  • Remember if you have an early-stage melanoma (stage 1 or 2), you are unlikely to feel unwell or have any additional symptoms other than the appearance, or change in appearance, of your mole or lesion. This is why you must contact your GP if you notice a new mole, lesion, nail streak or a change in a pre-existing area. It is always better to get checked out early. Melanoma is easier to treat and potentially curable if picked up early.
  • If diagnosed with a later stage melanoma (stage 3 or 4) you may experience other symptoms, for example at stage 3 some people experience swollen lymph nodes. Find out more.
