Genetic screening is the analysis of your DNA or genes to identify if you have gene mutations that are associated with certain diseases or cancers.
These tests are performed using a sample of your saliva or blood. These screening tests are helpful if you are concerned about your risk of developing a specific disease or cancer.
When you have a genetic screening test it can help you whether the result is negative or positive. If the results are negative, there is some reassurance that you are not at a higher risk of developing the specific condition or cancer. Should the result be positive, you will be able to take action and seek advice to reduce risks, help your family learn about their risks and undergo further investigations if necessary to identify conditions earlier.
All of us have a 1 in 2 lifetime risk of cancer. There many different risks such as environment, lifestyle and hereditary factors. About 10-15% of most cancers are due to hereditary genetic mutations. If you can identify this risk it can allow development of plans to help detect and treat any conditions earlier. You can also share information with relatives so that they can learn if they are also at higher risk of specific cancers or conditions.
The cancer screen analyses 30 genes known to increase the risk of specific cancers. These cancers include:
Cardiac Screen (Heart)
This screening test analyses 77 genes related to inherited heart conditions such as:
- Blood pressure
- High Cholesterol
