Sexuality in cancer and palliative care 1: Effects of disease and treatment.

All cancers and related treatments have the potential to affect sexuality and sexual function. This may result from impaired body function or altered body image, or from the emotional and psychological distress that often accompany diagnosis and treatment. It is increasingly acknowledged that issues surrounding sexuality are an important factor in quality of life for patients with cancer, and that sexuality is a legitimate area of concern for nurses in oncology and palliative care. However, issues relating to sexuality remain among the most poorly addressed in cancer care--possibly owing to lack of knowledge and expertise. There are also societal norms, myths and assumptions that may prevent nurses from broaching these issues. To provide this component of care, nurses need to have good communication skills, an open and non-judgmental approach, and knowledge of the potential ramifications of disease and treatment on sexuality.
