Pregnancy can affect your skin in many ways.
At Melanoma Institute Australia, we are researching how pregnancy affects moles and we would like to get you on board.

About the study



The study involves free review by a specialist Dermatologist and photographs of all your moles (you keep a copy). We need to see you twice during the pregnancy, and once 6 months after your baby is born.

To accurately determine the effect of pregnancy on moles, we need you to bring your sister. She gets a free skin check and mole photography too.

How to participate

To be able to take part of this study you need:

To be less than 26 weeks pregnant

To have a full biological sister 

To have less than 100 moles on your body (or less than 12 per arm) 

To attend 3 appointments (1 hour each) at the Institute in North Sydney.

Frequently asked questions

Why this study?

The effect of pregnancy on moles is controversial. Pregnancy may result in some changes in the appearance of moles due to hormonal factors and stretching of the skin. We are studying to determine which types of changes in moles are normal for pregnancy. We are comparing these to changes which occur in non-pregnant women.

How long does each visit take?

Each visit will take approximately one hour. You need to visit the same practice 3 months later and then 6 months after delivery.

Why do we need your sister?

We need a control to confirm that any changes in your moles are due to pregnancy. We do this by comparing the types of changes that occur in women of a similar age who are not pregnant. Your sister probably has similar risk factors for skin cancer to you, including: skin colour, number of moles, childhood sun exposure and sun burn, and family history of melanoma. Your sister will only need 2 visits, 3 months apart. She will not need to come again after the baby is born. She will have the same examination, and dermoscopic photography as you.

Is there any risk for my baby?

There is no risk for your baby if you take part in this study. All techniques used in this study are safe in pregnancy. We take close-up photographs of your moles with a regular camera and specialised magnifying glass.

Do I need a referral?

No. No referral is needed. We will send a courtesy letter to your GP and obstetrician informing them of your participation in the study.

Do I get a copy of the mole photographs?

Yes. We will share a copy via our secure app. They can be helpful in the future, if there is any concern that your moles are changing.
