Abstract
The internet has given rise to an information revolution of unprecedented magnitude. However, cancer information on the internet is not always correct. We had evaluated the top 50 sites by searching “Hai-gan” in Kanji, and found that less than 50% of those sites are posting the acceptable information about the treatment. To improve this disastrous situation, we are now trying to make the web site with the links to the reliable cancer information which we can recommend to patients and their families.
