“I believe that the information we gain from genetic testing should lay the foundation for the care we provide you and your family.”
— Dr. Dubard-Gault
Why do you study cancer genetics?

During my fellowship, I met a young mother who was a few months out of major surgery for metastatic cancer. I explained that we could use a genetic test to help inform her next steps for treatment, and she agreed it was a good idea. The test results revealed that she happened to carry a particular genetic mutation, which affected the drug therapy her doctors recommended. The results also gave her family members the opportunity to get tested for the same mutation. I really enjoy how sharing genetic information with patients can empower them to take control of their care and their future.

Metastatic A metastatic cancer is a cancer that has spread to other areas of the body by way of the lymph system or bloodstream. Mutation Any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment. Any change in the DNA sequence of a cell. Mutations may be caused by mistakes during cell division, or they may be caused by exposure to DNA-damaging agents in the environment. Mutations can be harmful, beneficial or have no effect. If they occur in cells that make eggs or sperm, they can be inherited; mutations that occur in other types of cells are not inherited. Certain mutations may lead to cancer or other diseases. A mutation is sometimes called a variant.
What do patients appreciate about working with you?

I think people value the information I can offer and the way I share it with them. Many patients aren’t aware of the ramifications of their genes — that they can affect how and when we provide care. For example, knowing the genetic profile of your cancer may help your doctors tailor a treatment plan specifically for you. More importantly, finding out that you have an increased risk of cancer could mean it’s a good idea to conduct screenings more frequently. The sooner a lesion is detected, the more likely we can remove it before it becomes cancerous. I also understand that discussing genetic information about increased risk can be stressful and that some people may need reassurance and time. I maintain an open-door policy, meaning that patients can make an appointment to discuss genetic test results when and if they are ready.

Gene The functional and physical unit of heredity passed from parent to offspring. Genes are pieces of DNA, and most genes contain the information for making a specific protein. Lesion An area of abnormal tissue. A lesion may be benign (not cancer) or malignant (cancer). Treatment plan A detailed plan with information about a patient’s disease, the goal of treatment, the treatment options for the disease and the possible side effects and expected length of treatment. A detailed plan with information about a patient’s disease, the goal of treatment, the treatment options for the disease and the possible side effects and expected length of treatment. A treatment plan may also include information about how much the treatment is likely to cost and about regular follow-up care after treatment ends.

Specialty: Genetics

Area of clinical practice

High risk prevention

Cancer genetics

I am the medical director of the Cancer Genetics Program at SCCA. The program features multidisciplinary tumor boards, which bring together experts from a variety of specialties to discuss treatment planning. Through our clinic, patients can receive genetic testing for predisposition to cancers as well as counseling and strategies to help manage increased risk. My areas of expertise include medical oncology and cancer genetics. Prior to joining SCCA, I completed a fellowship in cancer genetics at Memorial Sloan Kettering Cancer Center in New York. My main research interest is to better understand how genetic information influences patients’ decision-making about health care and life choices. I’m also interested in exploring ways to help people better access medical genetic information, talk about it with their families and use that knowledge to make decisions that fit their goals.

Genetic testing Tests that can be done to see if a person has certain gene changes known to increase cancer risk.

Clinical trials

We make promising new treatments available to you through studies called clinical trials led by SCCA doctors. Many of these trials at SCCA have led to FDA-approved treatments and have improved standards of care globally. Together, you and your doctor can decide if a study is right for you.


Many of our SCCA physicians conduct ongoing research to improve standards of patient care. Their work is evaluated by other physicians and selected for publication to the United States National Library of Medicine, the largest medical library in the world. See scientific papers this SCCA provider has written.

Your care team

At SCCA, you receive care from a team of providers with extensive experience in your disease. Your team includes doctors, a team coordinator, a registered nurse, an advanced practice provider and others, based on your needs. You also have access to experts like nutritionists, social workers, acupuncturists, psychiatrists and more who specialize in supporting people with cancer or blood disorders.
Registered nurse (RN)
Registered nurse (RN)
Your nurse manages your care alongside your physician and assists with care procedures and treatments.
Patient care coordinator
Patient care coordinator
Your patient care coordinator works closely with you and your physician and serves as your scheduler.


SCCA accepts most national private health insurance plans as well as Medicare. We also accept Medicaid for people from Washington, Alaska, Montana and Idaho. We are working to ensure that everyone, no matter what their financial situation, has access to the care they need.
