At Providence, you are treated by a multidisciplinary team of specialists involved in every aspect of your cancer care – including gastroenterologists, radiologists, surgeons, pathologists, medical oncologists, and radiation oncologists - who collaborate across multiple locations to provide convenient, connected care close to your home or work. As a patient, you will have access to:

  • World-class treatment options, including access to advanced technologies and the latest clinical trials.
  • Comprehensive care across the care continuum: continuing and supportive care including home health, skilled nursing, hospice, supportive/palliative care, in-patient/out-patient rehabilitation, nutrition, counseling, social work, wellness and support groups.
  • One of our values is to ease the way of our patients. As part of this, our compassionate, cancer navigators support and coordinate your patient care journey every step of the way.
Our approach to cancer care at Providence is to treat the whole person and not just the illness. You are at the center of a team of specialists whose common goal is to cure, reduce recurrence, and provide access to integrative medicine and supportive care services designed to improve your overall quality of life.

All cancer patients have access to have their case reviewed at a tumor board, also known as multidisciplinary cancer conference. Tumor boards provide a collaborative, multidisciplinary approach to your cancer care, bringing together oncology, radiology, pathology, interventional radiology, genetics, and ancillary specialists to aid in treatment planning and improved care coordination.

One of the most important members of your Providence cancer team is a specially trained nurse navigator, who provides compassionate support and will keep you informed and help answer your questions so you can feel confident and in control of your care.

Genetic counseling is a process of receiving risk estimates, accurate understanding, management planning and empowerment for individuals and families who are concerned about their risks. It involves meeting with a licensed certified genetic counselor to review your personal and family history, to accurately interpret genetic test results, and to receive compassionate support. Genetic counselors provide personalized recommendations for screening, prevention, and risk reduction.

Genetic testing may help to rule out an inherited syndrome, provide an explanation for the occurrence of cancer or heart disease in you or in your family and predict elevated risk of developing additional disease. For individuals with a current cancer diagnosis, genetic testing can provide valuable information to your treating physicians in developing the best treatment plan.

Genetic testing and genetic counseling testing results can provide management recommendations to help treat and prevent disease and can be used to more accurately advise family members.

  • Does insurance cover genetic testing and genetic counseling?

    Yes, the vast majority of patients have insurance coverage for genetic testing and genetic counseling testing. Our patient account specialists verify coverage prior to the consultation. Individuals may also check eligibility and co-pay information by calling their insurance provider.

    Genetic testing is billed by the third-party genetic testing laboratory directly. For most, the cost of genetic testing does not exceed $250. If the cost of the test is a barrier to you, your genetic counselor can discuss laboratory patient assistance programs and help you apply for them.

  • What is hereditary cancer and how much of cancer risk is inherited?

    Inherited cancer syndromes are typically due to inherited “errors” or mutations within specific genes that normally function to prevent cancer. These inherited mutations cause a loss of normal gene function and increased risks of developing certain types of cancer. About 5-10% of individuals have a cancer caused by an inherited cancer syndrome.

  • What is inherited heart disease and how much of heart disease is inherited?

    Hereditary cardiac conditions are typically due to inherited “errors” or mutations within specific genes that disrupt the normal growth or function of the heart and other parts of the circulatory system. These inherited mutations can cause increased risk for progressive heart disease, especially at younger ages, or even cause dangerous cardiac events and lead to sudden death. About 1 in 250 individuals have inherited heart disease.

  • Can I have genetic counseling and genetic testing for other conditions?

    Our genetic counselors are qualified genetics professionals for all types of inherited risks, and are prepared to discuss the risk of developing other disorders of familial concern, including hematologic and adult neurologic syndromes. They can also help interpret direct-to-consumer tests and provide clarity on the implications of results for you and your family members. See Genetic Services for more information.

  • How long does it take to get genetic test results?

    On average, genetic test results are available within 2-3 weeks.

  • What are the possible test results?
    • Positive: A harmful mutation identified that may increase risk of developing certain conditions.
    • Negative: No mutation identified.
    • Variant of Unknown Significance: Genetic alteration identified, but our understanding of it is limited at this time.
  • I just want genetic testing, why would I want genetic counseling too?

    Genetic testing is just one tool that genetic counselors use to provide you with the very best in personalized medicine that genetic testing alone cannot provide. Genetic counselors are genetic experts and remain up to date on the constantly changing field of genetics. They are trained to tailor, translate, and communicate complex genetic information into practical, accurate, and understandable decision-making information that you, your relatives, and your healthcare team can use to provide the best in individualized healthcare management. They help to insure the very best outcomes for you and your relatives.

  • I’ve already had genetic counseling, when should I come back?

    Continued contact with genetic professionals is advised for many individuals who have undergone genetic counseling and/or genetic testing. Over time, new technologies are developed, new genes become available for testing, insurance criteria for testing may change making testing more accessible and management updates for mutation carriers become available. Additionally, family histories change over time making reassessment of the family history beneficial. We recommend having genetic counseling if you have significant family history and you previously had genetic testing without seeing a genetic counselor. In addition, we recommend contacting your genetic counselor every few years.

    • If you previously had genetic counseling but genetic testing was not done: If you underwent genetic counseling without genetic testing, you may benefit from meeting with a genetic counselor again. The criteria for genetic testing have expanded, insurance companies are much more likely to cover genetic testing, and the cost of genetic testing has decreased significantly. A genetic counselor can help you review your options, order the appropriate test, and review your results and their implications.
    • If you previously had genetic testing which identified a pathogenic mutation (positive results): With time, more information becomes available regarding specific hereditary cancer syndromes. If your previous genetic testing identified a mutation, it is important to keep in touch with your genetic counselor periodically to review the most up to date information regarding cancer risks and management guidelines and to make sure that your previous genetic testing was comprehensive.
    • If you previously had genetic testing which did not identify any mutations (negative results): With time, more hereditary cancer genes are being identified, comprehensive genetic testing is becoming more accessible, and genetic technologies are advancing. If your previous genetic testing was uninformative because it did not identify any mutations, updated genetic testing may be indicated.
    • If you previously had genetic testing which identified a variant of unknown or uncertain significance (VUS): With time, more information becomes available and variants of uncertain significance may get reclassified. A genetic counselor can review the current literature and data regarding your VUS, discuss what is known, what steps may be taken to reclassify it, and recommend further genetic testing if indicated.
  • My doctor already did genetic testing on my cancer tissue, do I need more testing?

    Genetic testing for tumor molecular profiling (somatic) is different than genetic testing for inherited cancer risk (germline). Genetic testing of cancer tissue helps to characterize the tumor while genetic testing for inherited risk helps to estimate and reduce familial cancer risk. A genetic counselor can review tumor genetic test results in conjunction with your personal and family history to help you understand your results and your risk for an inherited cancer susceptibility syndrome.

  • I already did direct to consumer (DTC) genetic testing, how is this different?

    Some DTC companies, such as 23andMe and Ancestry, offer "health" tests. These tests are not diagnostic and should not be used to make medical decisions. If you previously had DTC genetic testing and were told you had an increased risk of developing a certain condition, such as cancer, a genetic counselor can review these results with you and, if indicated, order diagnostic confirmatory testing.

    In addition, DTC testing is very limited, looking at a few mutations while clinical genetic testing fully analyzes those and other relevant genes. Therefore, "normal" DTC testing results do not actually rule out hereditary cancer syndromes or other hereditary risks.

  • Can my genetic results be used against me?

    Federal and state laws provide protection against genetic discrimination. The Genetic Information Nondiscrimination Act (GINA) of 2008 is a federal law that protects people from health insurance eligibility discrimination including additional fees or costs and also protects from employment discrimination. GINA does not protect against all forms of genetic discrimination and does not specify protection from other insurance discrimination such as life, disability, and long-term care. Learn more about GINA. Our genetic counselors can discuss any concerns you may have regarding genetic testing and privacy.
