Cancer genetic testing could be considered if:
Knowing your genetic status can help with appropriate treatment plan and risk management options.
Results may help make an informed decision regarding most suitable options for individuals with particular gene faults, such as types of surgeries, chemotherapies, or on going surveillance. In some cases, they can also qualify you for clinical trials
Results may inform of your likelihood to develop cancer (a new primary) in future, enabling you to be proactive and discuss risk-reducing surgery, medicines that can prevent cancer from developing (“chemoprevention”), or vigilant screenings going forward.
If a gene fault is identified, it would enable your family members to explore their genetic status. They can get tested too and, if they also have inherited the genetic fault, they can get more frequent screenings and discuss risk management options.
