"Nothing is wrong, doctor": understanding and managing denial in patients with cancer

From a psychological perspective, denial is the process by which the mind defends itself against painful or threatening thoughts, feelings, perceptions, or information and may manifest in healthy or sick persons as well as in patients or those who care for them. For someone with a possible cancer diagnosis, there are several individual steps involved in the denial process, as the threatened meaning of one or more symptoms is sculpted into a more acceptable reality. Although most often felt to be a dysfunctional response, denial of illness is widespread and may serve an important adaptive or coping function, especially in a person facing the challenge of cancer. It may help a person cope with the various stages of their illness and treatment by allowing them time to process distressing information at a manageable rate. However, denial may also be dysfunctional, especially if it causes delay in seeking treatment for symptoms that present in the context of a true malignancy. Many clinicians misdiagnose denial when avoidance, disavowal, or another coping mechanism is invoked or when cognitive impairment or sensory deficits adversely affect perception. This article discusses denial in the context of cancer diagnosis, treatment, and prognosis and strategies for managing this common condition.
