This works when conditions are clearly distinguishable to a particular gender or age, such as prostate cancer or circumcision. It's more difficult to search for a subject such as colon cancer with such divisions. In this case, look for an alphabetical list of the contents to browse. For Internet sites that have a search feature, keywords or subject terms can be used to locate information within that site on a given topic.

Most will have a help section. If unexpected results show up, consult the help section to improve the chances of finding relevant information. They may go from very broad topics, such as women's health, to narrower topics, such as pregnancy, deeper in the site. If there is no search feature, several broad topics must be reviewed to find the specific information needed. As an alternative, some sites offer an alphabetical list of all topics to browse.
