CHESS is an interactive, internet-based computer program that will provide information, social support, and skill-building techniques. CHESS provides the latest medical, social, and legal information about prostate cancer (such as information on symptoms and treatments). It also provides help in deciding what treatment to choose, advice on where participants can go for help, information on how participants can make the best use of health and human services, and a way for participants to share concerns with cancer information specialists and other survivors of prostate cancer. Participants who take part in the CHESS interactive services will not need to give their names. Participants can talk with other people by sending anonymous (your identity will be unknown) messages through the CHESS computer network.
