Assessment of Inherited Risk
- Family Tree/ Pedigree drawing
- Risk Assessment
- Hereditary Cancer Syndromes
Drawing a family tree or “pedigree” can provide clues to whether or not your family has a higher risk of cancer than the general population. If an important gene isn’t working properly because of an inherited change (referred to as a mutation), then the risk of certain cancers may increase.
We use information that you provide to draw and analyse your pedigree. We can also help you track down important medical information about your family. It remains confidential.
You can download the Sydney Cancer Genetics Family History Questionnaire and discuss the completed form with your doctor.
Genetic Counselling and Testing
- Initial Mutation Search eg BRCA1
- Predictive Genetic Testing
- Founder Mutations
- Tumour Testing
Not everyone wants or even needs a genetic test. However, for some families a genetic test, performed on a simple blood sample, can provide important, useful information.
At Sydney Cancer Genetics, genetic testing is organised separately from your medical consult and there is never any obligation to have a genetic test. We make no money from any testing ordered so you know we are always acting in your interest. Personalised screening advice and risk reducing strategies can be provided, even if no genetic testing is done.
Cancer Prevention and Risk Management
- Personalised screening advice
- Options to reduce risk
- Family Planning Support
Most cancers occur by chance. Mistakes get made in the DNA when a cell copies itself. If these mistakes are in growth genes or cancer protection genes, a cancer can occur. This kind of cancer is not inherited and tends to occur at an older age. We can discuss strategies to screen for and reduce your risk of this kind of cancer.
For some families, their risk of a particular cancer may be quite high. In these circumstances, screening should be personalised and should start at an earlier age. At times, specific surgery or medication may be the best option to reduce cancer risk.
Sometimes a gene with a fault in it is identified as causing the high rate of cancer in a family. Some families may choose to use techniques such as IVF and PGD to ensure that only the gene without the fault is passed on to the next generation.
We can determine together what options suit you best.
