Most of the time when a biopsy is performed, it’s to test the tumor tissue for cancer cells. However, science has evolved so that now we don’t need to take a tissue biopsy from a cancer patient in order to ensure they are getting the best possible care! Instead, we can now use a simple blood test to look for these cancerous cells and find out which mutations are making them grow.
It’s recently been discovered that every cancer tumor naturally sheds some of its mutated cell DNA into the bloodstream. Cancerous tumor cells release mutated DNA into your bloodstream in discrete packages called exosomes. These exosomes travel throughout the body and turn normal healthy cells into cancerous cells. Meanwhile, your normal/healthy cells release the normal versions of the same DNA (via exosomes) in order to counteract the cancer causing exosomes.
"Of patients with targetable mutations that were identified via liquid biopsy, 86% achieved either a complete response, partial response, or stable disease, patients whose actionable mutations were detected by the liquid biopsy responded favorably to targeted therapies." 1
A Liquid Biopsy Labs test is the only liquid biopsy test that checks your blood and measures the ratio of the key mutations that drive your cancer in these two competing exosomes (cancerous and non-cancerous) to determine if there’s an increase in the metastatic process. Other liquid biopsies only measure the total amount of circulating DNA – which can be from dead tumor cells, active tumor cells, or exosomes.
Liquid Biopsy Labs' liquid biopsy process can be used for diagnostics and early detection – and is also highly effective when the genetic sequencing of a person’s cancer has already been completed and we want to ensure their targeted therapy or immunotherapy treatment is working.
Liquid biopsies can identify cancer-causing mutations in as little as 0.02% of your total DNA. This means it can tell you when a tumor is present in your body before it shows up on even the most advanced imaging tools, such as PET/CT.
