A groundbreaking blood test known as Galleri has been developed to detect over 50 types of cancer through a simple blood draw. This test identifies DNA markers shed by cancer cells into the bloodstream, enabling early detection of various cancers, including those that are typically hard to diagnose in initial stages. Currently, the Galleri test is available by prescription for individuals aged 50 and older, or for those under 50 with specific risk factors such as a family history of cancer. However, it is not yet approved by the FDA, and its $949 cost is not covered by insurance, requiring patients to pay out-of-pocket.
While the test offers promising advancements in early cancer detection, its efficacy varies depending on the cancer type and stage. A 2021 evaluation revealed that the Galleri test detected only 16.8% of Stage 1 cancers, indicating limitations in identifying very early-stage malignancies. Additionally, there are concerns about false positives, which could lead to unnecessary invasive follow-up procedures and associated stress for patients. As the test is not yet FDA-approved and lacks insurance coverage, individuals considering the Galleri test should consult with their healthcare provider to thoroughly discuss potential benefits, limitations, and financial implications before proceeding.
