The World Health Organization predicts that the number of people in the world who will be newly diagnosed with cancer will increase from 18 million in 2018 to 29.5 million in 2040. It is also believed that the number of deaths will increase from 9.5 million in 2018 to 16.4 million in 2040. Cancer is a major public health problem in Croatia likewise in the rest of the world. In order to reduce the number of cancer patients and deaths caused by oncological diseases in Croatia, as well as in Europe, numerous preventive programs are implemented. Croatia has four National preventive programs covering lung, breast, cervical and colon cancer. The goal of all four programs is to detect the disease at an early stage in order to increase the possibility of treating the disease, improve survival rate and reduce mortality. Croatia has also declare National Strategic Framework against Cancer by 2030 and in Europe the European Code against Cancer was adopted. A lot of information is nowdays available in the media, including information about health. Disinformation assoiciated with healthcare undermines trust in the entire healthcare system. Although the media can convey inaccurate health information, it can be very useful in conveying true and important information about health and disease. In addition to conveying information about health, the media often report on healthcare providers. Nurses are still portrayed quite stereotypically in the media, but their media visibility is increasing and it is used for communication with patients and education of patients, but also for the purposes of mutual communication and exchange of experiences. The aim of the research part of this paper was to explore the influence of the media on the attitudes, behavior and knowledge of the general population toward oncological diseases. The great role of the media in the representation of cancer-related information was confirmed. It turned out that the most used medium for obtaining information is the Internet, where information is not always trustworthy. The great value of medical staff in providing cancer-related information has been proven. The media could be used for the purposes of cancer prevention, since interest in the existence of a show about cancer that wolud be hosted by competent healthcare professionals has been shown. The role of the nurse is very important because she can participate in stopping the spread of misinformation related to cancer within her competences, but also she directs patients to trace trustworthy sources of information. A nurse can write scientific articles based on science, knowledge and experience and work on their own knowledge and communication skills to keep up with potential new discoveries in the oncology.
