Following several tumour-specific cancer awareness campaigns, a more general cancer symptoms approach was piloted. ‘Know 4 sure’ was the headline for the campaign, which focused on four key symptoms that are indicators for a number of cancers, including less common ones. All the adverts and materials encouraged people with any of the symptoms to go to their doctor.
The ‘Know 4 sure’ cancer symptoms campaign pilots took place in five areas in England from 14 January to mid-March 2013.
