Psychological aspects of oncology.

The patient with cancer presents the physician with challenging psychological issues: maintenance of an effective and understanding physician-patient relationship, in the context of optimal medical care, and alertness to signs of significant psychologic symptoms that may occur more commonly in the course of cancer. The closest relative, also under great emotional stress, must be considered in communications about the patient's clinical state and treatment. Psychological aspects of oncology are a demanding component of total care of the cancer patient, yet an integral part of optimal cancer care.
