Genomics - The Next Step for Precise Cancer Care

Today it’s well known that a person’s genes have an impact on their health. The genes we inherit from our parents can help us understand our risks for diseases like cancer.

But not all cancers are the same, even within the same tumor site. If two people have breast cancer, they may each respond to a completely different treatment plan. It all depends on the genetic makeup of their unique tumor sites.

To take the next step for cancer care, Community Health Network leans on the latest technology in the field of oncology. It’s called genomics, and it’s leading the way for more precise, personalized treatments for cancer patients.

What is Genomics? 

Genomics is the study of the human genome, or a person’s entire genetic makeup. When we’re talking about cancer care, genomics is the study of the genetic makeup of a person’s unique tumor site.

Every case of cancer is unique, so care should never be one-size-fits-all. By looking at the genetic makeup of your tumor site, your oncology team learns how to treat YOUR cancer — not just any cancer.

Genomic testing may reveal how your cancer is likely to grow or spread. It can help your care team pinpoint a drug or treatment plan that’s more likely to succeed, all personalized to your body alone.

When you face cancer at Community, you’re not just a number. You’re an individual, and your care will always reflect it.

How is a Genomics Test Performed?

While genetic testing is used for early detection of cancer, a genomic test is only performed after cancer is detected.

At this point, the patient has already had a biopsy and received a cancer diagnosis. If the patient and caregiver agree on a genomics test, it’s a noninvasive procedure. Oftentimes the tissue sample collected from a previous biopsy or surgical procedure can be used to examine the tumor’s genetic makeup.

In certain cases where the previously collected tissue is small or its cells have been exhausted, your provider might suggest what’s called a liquid biopsy. A liquid biopsy is as simple as getting blood drawn. It’s non-invasive, and helps our lab get a good look at your cancer genomics without calling for another surgical procedure.

How to Talk to Your Provider About Genomics

During the course of cancer care, a provider will generally suggest genomic testing if they think it’s the right step for their patient. In some cases genomic testing will open the door to a new avenue of treatment, or give the patient additional options.

If your oncologist hasn’t suggested genomic testing yet, it’s always a good idea to be your own advocate. Ask your provider if genomic testing is appropriate for your diagnosis. You can even send them a message through MyChart right now.

If your provider agrees that genomic testing might be right for you, ask which specific tests you should consider. What are the benefits of each test? What are the risks, if any? Is there financial support available for the tests you’re considering?

All of these questions can help you become a more informed patient, and are well within your right to ask! Start the conversation on MyChart today, and see if genomics testing might be part of your cancer care journey.
