Details on demand: consumers, cancer information, and the Internet.

An increasing number of patients and their families have Internet access and use it to make sense of their cancer experience.

Several organizations have attempted to create evaluation tools for cancer information on the Internet. They are, for the most part, untested, but they can serve as a practical guide for coaching patients and family members on the use of the Internet. Evaluating Internet information with guidelines, dealing with Internet-savvy patients and families, and the use of e-mail in clinical practice are discussed.
