Counting Right Arm Moles Reveals Cancer Risk

A study has suggested that counting the number of moles on your right arm could reveal the risk of skin cancer. 

Researchers at Kings College London have suggested an examination of their right arm to see if it reveals:

  • 11 or more moles
  • measuring at least 2mm in diameter

People with this ‘above average’ number of moles on their right arm are likely to have more than 100 moles across their whole body, which is linked to a higher risk of malignant melanoma.

How Many Moles?

  • The average Caucasian has between 20 to 30 moles
  • People with 100 or more moles are thought to have at least 5 x the normal risk of malignant melanoma
  • Those with 50 moles are thought to have 2 x the risk

Malignant Melanoma and Moles

A mole is a collection of hundreds of melanocytes – cells that contain melanin, which gives skin pigment.

Having lots of moles is a sign of particularly active melanocytes which points to a higher risk of malignant melanoma.

Malignant melanoma is the most serious form of skin cancer and is potentially fatal. However, catching it early gives the best possible outcomes, which is why the public are encouraged to be alert for worrying moles.

Veronique Bataille, a consultant dermatologist at King’s College London and one of the researchers involved in this week’s mole study, explained that the concern with moles is not just that an existing one will become cancerous. 20-40% of melanomas are thought to arise in long-standing moles. The rest develop in single melanocytes that go ‘bad’.

Worrying Moles?

Patients concerned about their moles are recommended to seek an appointment with their doctor or a mole removal specialist.

Anybody who has a ‘suspicious’ mole – whether they are generally moley or not – is advised to get it checked as soon as possible. Look for:

  • Asymmetry – uneven mole shape
  • Borders – rough looking edges
  • Colour – any unusual variation
  • Diameter – a larger mole could be a worry
  • Evolving – any mole which appears to be changing in any way should be investigated
