Know 4 sure campaign

Last reviewed: 10 July 2025

Public awareness of the signs and symptoms of cancer can support timely presentation in primary care and drive earlier diagnosis. Be Clear on Cancer (BCOC) campaigns were carried out to raise awareness of key symptoms of cancer and encourage people to go to their GP without delay.

Why were the campaigns run?

Following several tumour-specific cancer awareness campaigns, a more general cancer symptoms approach was piloted. Know 4 Sure was the headline for the campaign aimed to raise awareness of key symptoms which are indicators for cancer, including less common sites, and encourage people to visit their GP. The Know 4 Sure campaign ran from January to March 2013.

What were the aims of the campaign?

Know 4 Sure targeted people over 50 to raise awareness of unexplained bleeding, lump, weight-loss and pain. All the adverts and materials encouraged people with any of the symptoms to go to their doctor.
