This video is an overview of genomic testing for cancer patients. Cancer genomic testing is a tool that helps doctors understand the unique genetic changes in cancer cells. This understanding allows for more personalized treatment plans, which can lead to better treatment outcomes.
First, let's answer a few key questions for genomic testing for cancer.
What is genomic testing? Genomic testing looks at the DNA of your cancer cells, not the DNA of your normal cells. It helps doctors see if there are specific genetic changes that might be causing the cancer to grow. By understanding these changes, doctors might be able to make a personalized care plan to fit your needs.
When is genomic testing used, and what is it for? Genomic testing is often used when you're first diagnosed with cancer. It can also be helpful if your cancer isn't responding to treatments or if it comes back after previous treatment. The test can give doctors insights into how the cancer is behaving and help doctors choose the right treatment based on the cancer's genetic makeup. Additionally, genomic testing can find specific genetic markers that might lead to new treatment options, such as targeted therapies or even clinical trials.
How is genomic testing done? Genomic testing is typically done using a biopsy sample taken from the tumor. Doctors can also use tissue from a prior surgery to do genomic testing. The sample is sent to a lab where special tests look for genetic changes. Once complete, the lab sends a report to the doctor who ordered it. This report and any new recommendations are then communicated back to the patient.
When might your doctor recommend genomic testing? Your doctor might suggest genomic testing if any of the following situations apply to you:
If you've been diagnosed with cancer and want to understand more about it, genomic testing can help identify specific genetic changes in your cancer. This information helps doctors understand how the cancer behaves and how it might respond to treatment, allowing them to tailor your care.
If your cancer isn't responding to standard treatments and your doctor wants to explore other options, genomic testing can reveal other possible treatments or targeted therapies that might work better based on the cancer's genetic makeup.
If you're thinking about joining a clinical trial where targeted therapies might be available, many trials offer treatments designed for specific genetic changes in cancer. Genomic testing helps your doctor determine if you're eligible for these trials and matches you with the right one.
If your cancer has returned after treatment and you want to find the best way to manage it, genomic testing can reveal new genetic changes or resistance patterns, helping doctors choose the most effective treatment for managing the recurrence.
Genomic testing can provide important information that can help guide your treatment decisions. It may not be necessary for every patient, but it's a powerful tool and can give your doctor a clear picture of your cancer.
