Understanding Hereditary Cancer Risk Screenings

  • While there are still many unknowns in relation to cancer, we do know that certain types are hereditary, which is why some families seem to have a higher incidence than others. These hereditary genes carry markers that can be detected in blood and saliva through a simple test, then analyzed to indicate an increased risk of developing cancer. Though impossible to predict outcomes with absolute certainty, hereditary cancer risk screenings provide crucial patient information that is otherwise invisible and undetectable. Once a patient is tested, medical providers can use results to manage patient care more effectively in order to provide better health outcomes. 


  • Looking closely at a patient’s family history is often helpful, and even crucial, in preventative care. It can provide warnings about potential health problems and concerns. Testing for hereditary cancer markers can help individuals take action. If a patient is found to have increased risk for cancer, medical providers can adjust their monitoring accordingly. Implementation of improved monitoring can catch cancer in an earlier stage, leading to better prognosis and patient outcomes. 


  • There are many factors that might recommend a patient for testing. According to the National Cancer Institute, some of these factors include: 

    • A family member with an early onset of cancer, generally before 50 years of age. 

    • A person in your family who has had multiple cancers.

    • Family members with rare cancers, such as pancreatic or ovarian.
