Studies examining the prevalence of mental disorders in cancer [1,2] show that most cancer patients do not meet the diagnostic criteria for any specific mental disorder; however, many patients do experience a variety of difficult emotional responses.
Psychosocial distress exists on a continuum (see figure below) ranging from normal adjustment issues through the adjustment disorders of the fourth revised edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR); to a level close to, but below, the threshold (i.e., meets some diagnostic criteria but not all) of diagnosable mental disorders; to syndromes that meet the full diagnostic criteria for a mental disorder (e.g., major depressive disorder). This summary focuses primarily on the less severe end of this continuum: the normal adjustment issues, psychosocial distress, the adjustment disorders, and cancer-related anxiety. (Refer to the PDQ summaries on Depression and Post-traumatic Stress Disorder for more information.)
Anxiety is often manifested at various times during cancer screening, diagnosis, treatment, or recurrence. It can sometimes affect a person’s behavior regarding his or her health, contributing to a delay in or neglect of measures that might prevent cancer.[6-8] For example, when women with high levels of anxiety learn that they have a genetically higher level of risk of breast cancer than they had previously believed, they might perform breast self-examination less frequently.
For patients undergoing cancer treatment, anxiety can also heighten the expectancy of pain,[10-12] other symptoms of distress, and sleep disturbances and can be a major factor in anticipatory nausea and vomiting. Anxiety, regardless of its degree, can substantially interfere with the quality of life of patients with cancer and of their families and should be evaluated and treated.[13-15]
In this summary, unless otherwise stated, evidence and practice issues as they relate to adults are discussed. The evidence and application to practice related to children may differ significantly from information related to adults. When specific information about the care of children is available, it is summarized under its own heading.
