On 7th November 2017, the Marie Curie Legacy Campaign began an awareness and educational effort aimed at the public and decision-makers. Leveraging the 150th anniversary of Marie Curie’s birth, a media campaign was launched, via both social and traditional media, to attract attention to radiation treatments in cancer. To date, this awareness campaign continues to address perception and knowledge issues through national media campaigns, where issues to be targeted are selected according to the barriers in particular national contexts. With the support of the National Societies and by engaging national stakeholders, the national awareness campaigns continue to inform the public on the benefits of using radiotherapy to cure cancer, and address national concerns regarding the barriers that prevent radiotherapy being used to its optimal level so more lives can be saved.
