The campaign is inspired by the charity’s striped logo which is based on DNA gels that scientists use to find cancer cells.
People can also get involved with Stripe a Pose by posting photos of themselves in their stripey clothes on social media on 20 September and using the hashtag #StripeAPose
Adam Fletcher, Chief Executive Officer of Cancer Research Wales said:
“Cancer Research Wales is the independent Welsh cancer research charity and our mission is to unite Wales against cancer through world-class research.
“Today, we’re calling on the people of Wales to support us by joining in with Stripe a Pose at school, work or with their friends on 20 September.
“It’s easy to do - put on your best stripey socks, your favourite stripey t-shirt, your most colourful stripey jumper, your stripiest beanie hats or scarf and unite with us against cancer.
“You can also donate £1 or however much you’d like to Cancer Research Wales and join in the fun online by posting pictures of you in your favourite stripey clothes and using the hashtag #StripeAPose.
“1 in 2 of us will develop cancer and every week in Wales, 175 families lose a loved one to cancer, so please help us deliver hope to people affected by cancer in Wales by taking part in Stripe a Pose on 20 September.”
