[When evaluating health information, ask] is the information accurate? When assessing the accuracy, try to determine whether the information is supported by evidence from scientific studies, other data or expert opinion. If you receive information from a medical journal, note the size and category of the study. Read the article carefully to see if the authors discuss any limitations . . . of the study. . . .
If you receive information from a secondary source such as an Internet site or a newspaper article, keep in mind that you are relying on another person's interpretation of the data. . . . Although your local newspaper may provide excellent information on certain topics, it lacks the expertise of a medical journal or a national organization specializing in that field of cancer.
