The organisation is approaching agencies directly and plans to launch its ninth annual campaign in June. Last year, Delaney Lund Knox Warren & Partners created a viral, press and poster campaign starring the pop star Rachel Stevens.
In the 80-second viral, "Rachel gets fruity", a scantily clad Stevens told male viewers to put their hands down their trousers and get hold of their testicles.
She went on to explain how to detect cancerous lumps and bumps.
The press execution showed Stevens holding a plum and displayed the campaign website address, www.rachelgetsfruity.com.
