The Melanoma Foundation ambassador said she was 25 and with no history of skin cancer when she was diagnosed with melanoma.
A small freckle on her arm had changed colour and become itchy when she finally had it checked.
She was shocked to be given the diagnosis. Wilson is now clear of cancer but still checks her skin regularly and has yearly checks with a dermatologist.
She knows her childhood spent outdoors unprotected from the sun played a large part in her cancer.
"I don't ever remember covering up against the sun or using sunscreen."
Wilson is now extremely careful to protect herself and 18-month-old son Harper from the sun.
"You can have fun outdoors and still be safe from sunburn by following the slip, slop, slap and wrap rules."
SunSmart Week runs until Saturday.
