Goal of the thesis was to find out what nutritional regime is used by oncological patients, what is the offer of information about alternative medicine and what quality are websites with information regarding nutritional regimes of oncological patients. To evaluate the influence of other nutritional regimes we looked for organization and provides who perform alternative treatment on the world wide web. During the research we discovered that there are many providers of the alternative treatments in Slovenia, but only a fraction of them in present on the world wide web. Responses of providers were poor, we only got 13 replies of 23 requests. We used Sandvik scale to evaluate the quality of the websites. The quality of these sites was socred on a point system. Most of the websites were of medium quality, which is a concern. On the online search in Google, we are looked for search phrase “alternative cancer treatment”. We reviewed first 50 links. 40 % of which were associated with article of alternative cancer treatment. During the research we discovered that there are many providers of alternative treatments who do not have any formal healthcare education. They also think that patients with cancer seek their help too late and therefore alternative treatment is not successful. Results gathered valuable information to plan following healthcare measures for treatment of cancerous disease in Slovenia.
