A campaign against cancer has been launched by Atomic Kittens singers Liz McClarnon and Natasha Hamilton.
The singers teamed up with Boots to launch its "mole mates" campaign and urged Britons to call up a friend to help check their moles, which may turn out to be melanoma.
The move came after the high street chemist found that almost half (45percent) of people found it difficult to check their moles properly when they were in hard-to-reach places.
The singers claim its better to get friends to help out - even if the moles are in a private place.
The study also found that 13percent said they did not check their skin for warning signs of melanoma because they had too many moles to look at.
"I have a few moles on my back and I'm really aware of the importance of getting them regularly checked out by my doctor, just for peace of mind," the Daily Star quoted Natasha, as saying.
"As well as the professional checks, I get my mate Liz to check them on a more regular basis, as they are so difficult to see yourself. Liz just keeps an eye out for any changes in appearance to the moles.
"It only takes a few minutes to do, it's so quick and easy that it can be done when you're getting ready before a girly night out," she added.
Boots Scientific Suncare Advisor Mike Brown said friends or partners should look out for the following warning signs on moles - steady growth, uneven dark colour or darkening in colour, irregular, often changing outline, or a large size of a quarter of an inch or more across.
