Scientists are getting very good at identifying genes that can cause diseases ranging from prostate to breast cancer. Early diagnosis is crucial and genetics is proving a powerful tool for medicine. Inherited genetic diseases are caused by faulty forms of a single or a group of genes that are passed on from one generation to the next.

Single genes that are responsible for inherited genetic diseases, such as the ones responsible for familial Alzheimer's disease and cystic fibrosis are currently under investigation with the hope of developing tests to identify faulty genes.

More complex disorders are also being investigated. Disorders that not only involve faulty genes but environmental factors as well, such as heart disease, high blood pressure diabetes and lung cancer are also being investigated using a molecular techniques.

But this new technology, raises some very difficult ethical issues.
Who should be screened and who should have access to the results are just some of the numerous and difficult questions been asked?

Insurance companies have a duty to protect the common citizen from mishaps. Or do they? What will be the impact of genetic screening and the ability to obtain medical insurance?

Should a test be conducted if there is no known cure for the disease been tested for?

What are the advantages and disadvantages for testing for a life threatening disease that as yet has no known cure?

Should insurance companies have access to people's genetic information?

Should insurance companies make it necessary for clients to undergo genetic screening before being given cover?
