Chantix, a smoking-cessation treatment, got the most drug hits.

The terms “pregnancy” and “cancer” were the two most commonly Web-searched conditions in February 2008, according to a listing of the 20 most commonly searched health conditions released April 10 by comScore Inc. The terms “pregnancy” and “cancer” garnered 8.8 million and 7.7 million Internet search queries respectively.

“It’s not too surprising that some of the most common health conditions such as diabetes, depression and flu have made the list, but it’s interesting that these terms generate fewer searches than significantly less prevalent conditions like cancer and pregnancy,” said Carolina Petrini, comScore senior vice president, in a press release. “A reason for this may be the life-changing nature of a cancer diagnosis or a pregnancy.

“When facing a serious illness like cancer or after becoming pregnant or considering pregnancy, consumers often turn to the Internet to search for information and educate themselves in a private setting,” Petrini said. “comScore’s findings, along with information about the search popularity of branded terms, provide meaningful insights into the ways consumers use searches to find health information online.”
