Changing Trends of Cancer diagnoses

1. The data presented within this article was gathered by the National Cancer Institute (NCI), the Center for Disease Control (CDC), and the American Association of American Cancer Registries (AAACR). The data related to mortality rates was provided by the National Center for Health Statistics. 2. The sponsor of this research was not explicitly stated in the article however it based on data received and analyzed each year. The compilation of this data is a group effort by the NCI, CDC, NAACR, and the American Cancer Society. The primary source of this data is the Journal of the National Cancer Institute. 3. I believe that the sponsor of this study does not have a particular result that they are trying to find that might create a bias within the data. Rather, I think that the sponsor of this research is more interested in analyzing the changes in cases of cancer incidents. The article mentions the changing trends and the decrease in cases of certain types of cancers while noting the increase in other types of data. 4. The research analyzes incidence data ranging from 1992 through 2007. Also, from the number of American medical organizations listed who collaborated on this project, i would guess that the data is a collection of cases within the United States of America, and does not include a global-wide research study, however the report does not state that assumption. 5. The results are communicated in an informative manner. However this article is a selction of the data composed in the primary source document who's title is "Annual report to the nation on the status of cancer, 1975-2007, featuring tumors of the brain and other nervous system." Thus the author of this article chose certain pieces of information to expose within his article. The title of this smaller secondary source article labels lung cancer. Thus I think that the author wants to target readers who have particular interest in lung cancer rates, particularly since lung cancer is one of the more popular forms of cancer, and thus will bring in a larger body of readers to his own internet article. In conclusion, i think that the information presented in the articel was not compiled from a biased research but i do think that the author of this article reporting on the research study presented in the Journal of the National Cancer Institute had a bias when when deciding how to taret his audience. 6. There are no graphs used in the report of this data.
