Moles on the body largely influenced by genetics, a new study reveals – ScienceDaily

A study published this week in a journal Research on pigments and melanomas has found that genes have a greater impact than previously thought, not only on the number of moles you have, but also where they are on your body.

Survival of skin cancer affects gender, and patients show a higher survival rate related to melanoma sites that tend to occur in the lower body, rather than men affected in the upper body, neck and scalp. .

In this study, a team from King & # 39; s College London analyzed a large group of 3,200 healthy twins, predominantly females, and counted moles on the head and neck, back, abdomen and chest, upper limbs and lower limbs.

They found that:

  • In women, the smallest genetic effect on the number of patches was on the back and abdomen (26%) and the highest on the lower limbs (69%).
  • The higher number of moles on the lower limbs of women is likely to be exposed not only to the sun, but to the related genetic makeup

Lead researcher Dr Alessia Visconti, of the Twin Studies Department at King's College London, said: "For some time now, moles have been a major risk factor for melanoma skin cancer. With this research, we now know that there is not only the number and position of moles on the body is largely due to genetics.

"Our results add to previous evidence indicating that greater sun exposure is unlikely to be the reason why women have more patches on their feet.

"Although exposure to the sun adds to the number of moles and the risk of skin cancer, policymakers, campaigns and health researchers will need to consider a gender-specific genetic element when developing strategies for the prevention and treatment of skin cancer."
