1.What is cancer genetics?

Cancer is a genetic disease which is caused by changes to the genes which control the way our cells function (how they grow and divide).  Certain gene changes can cause cells to evade normal growth controls and become ‘cancer’.

Hereditary cancer predisposition syndromes occasionally exist within families. During a cancer genetics consultation, information is provided concerning heritable cancer-causing genes, how they are inherited and how any resulting cancer risk can be managed.

2.Is cancer inherited?

Not all cancers are inherited, however, certain cancers are caused by heritable factors.  The Cancer Genetics Departments and Services can provide genetic testing and advice on the management of cancer inheritance.

3.What are genes?

Genes are a special set of instructions inside the cells of our bodies that parents pass on to their children.  Genes contain information which tells our bodies how to grow and work. Genes are also responsible for many things, such as the colour of our eyes and the size of our feet.

4.Why have I been referred to the cancer genetics department?

You have been referred to a Cancer Genetics Department to assess your cancer family history and your potential eligibility for cancer genetic testing.  It is likely that your doctor recommended you for referral, following your consultation and discussion with them.

Diagnostic and predictive appointments to patients are made on receipt of an appropriate referral from a GP / Doctor.

5.What is cancer genetic counselling?

Genetic counselling for cancer involves the provision of verbal and written information on specific cancer syndromes.  Visual aids may be used to inform patients on their cancer risks and relevant risk-reduction strategies.

6.Who can benefit from cancer genetic counselling?

Anyone who has concerns about increased cancer risk in their family may benefit from genetic counselling.  Some concerns may be addressed by your doctor who can help decide whether a referral to a cancer genetics service is necessary.

7.‘What is the role of a genetic counsellor?

The role of the Genetic Counsellor involves the following and much more:

  • recommend genetic tests.
  • look at the results of tests.
  • explain how gene changes can cause genetic illnesses.
  • talk about how likely it is that a genetic illness will be passed to a child.
  • talk about options on what to do next.
  • provide support and resources
  • refer patients for appropriate disease screening.
  • are involved in research, policy and genetic education

8.How can cancer genetic counselling help me?

There are a number of ways in which you can be assisted through genetic counselling;

Genetic Counsellors provide information, support and counselling to both individuals and their families,

They can outline your likelihood of inheriting a cancer gene alteration (based on your family cancer history),

They can discuss cancer risk management plans with you,

They can also discuss any risks, benefits, and/or limitations of genetic testing.
