To examine the various concerns of patients after being diagnosed with cancer as well as the availability of information to address concerns from the time of diagnosis to the completion of treatment, we analyzed data from a longitudinal study of 731 adults recently diagnosed with cancer. Concerns about the effectiveness and side effects of treatment and family stress were most common after diagnosis. Information about the diagnosis and treatment plan was readily available to patients, but information addressing social, lifestyle, and financial concerns was less available. Significantly more information was desired regarding the long-term implications of treatment and disease.
