The survey extracted 2011 articles on cancer from the databases of five companies using 1 search terms from the morning and evening articles published in the national newspaper in 5, and analyzed the articles according to the content.According to the report, 52 articles, which is about half of the articles published, listed one or more cancer-affected sites.

　The largest number of publications was 575 cases of lung cancer.This is followed by 331 cases of leukemia, 302 cases of breast cancer, 261 cases of liver cancer, and 228 cases of colorectal cancer, but these do not necessarily match the ranking of the actual number of deaths and morbidity per year.

　Next, we examined 597 articles containing pre- and post-cancer information.
Before illness, there were 86 articles on cancer prevention, 73 on symptoms, and 98 articles on screening and early detection, while 206 articles on treatment after illness and prognosis. There were 111 articles about the recovery period and 82 articles about the terminal period, and the number of articles after the illness was overwhelmingly large.

　In the theme of the article, social problems such as trials and medical malpractices were the most common, reaching 797 cases.Next, there were 762 cancer-related book publications and events, 653 articles related to the Great East Japan Earthquake that occurred this year, and 650 articles related to celebrities.

　Approximately 45% of Japanese cancers have a low rate of preventive action and screening, even though it has been shown to be due to preventable risk factors.Therefore, the population approach to cancer prevention is one of the public health issues.Oka Lab has to consider what the public can learn from the information sent by the mass media, but if the number of articles focusing on prevention and screening increases, it may actually encourage screening and preventive actions. I think there is.
