The contribution of molecular genetics to the understanding and management of cancer: potential future applications and implications for nurses.
Cancer is an immense medical problem and as a cause of mortality it is second only to cardiovascular disease. Much of the current understanding of cancer is owed to epidemiologists who have discovered a number of causative factors implicated in its development. These causative factors can be divided into genetic, chemical, physical, viral, radiation, immune and hormonal factors. Further advances in understanding have been made over the past decade from contributions made by the field of molecular biology. From investigation and examination of the molecular processes involved in the development of cancer it is becoming increasingly clear that changes in the genetic material of the cell nuclei are the final common pathway to cancer, whatever the initial aetiology. This article will attempt to elucidate the contribution of molecular genetics to the understanding of the likely mechanisms of carcinogenesis, the management of cancer, potential future applications and directions and the implications for nurses arising from this relatively new and evolving field of knowledge.
