Galleri Multi-Cancer Test

- + 1 in 20 tests results in a potentially life-saving early diagnosis.
Prenuvo MRI Scan
Prenuvo MRI is a state-of-the-art whole-body scan that captures high-quality images without radiation. The scan uses a super-conducting magnet and diffusion weighted imaging to detect abnormal tissue density across your entire body, including all major organs.
Overview
- + Detects 500+ conditions and diseases through full-body MRI scanning.
- + Identifies serious issues like aneurysms, tumors, MS, cardiac lesions, and more.
- + Leads to earlier intervention, with up to 4x higher survival rates through early detection.

cancer screening FAQs
Click the drop down for details on each question.
How much do the early cancer detection tests cost?
Galleri is $950 and Prenuvo is $2,500.
Where will the Prenuvo scan take place?
Prenovo scans are not performed at our West Village clinic. Our concierge team will coordinate your appointment at Prenovo’s Midtown Manhattan location and ensure a seamless referral experience.
Who should not get a Prenuvo whole-body MRI?
A Pet-CT scan uses Gamma and X-ray radiation and is rarely used to screen for cancer. PET has limited use in the kidneys, ureters, and bladder because the radioactive injection is excreted through the urinary system and is highly concentrated in these areas during the scan. The Prenuvo scan does not have these issues and is more sensitive than PET-CT for tumors of the urinary system.
What should I expect during my scan?
The scan takes less than an hour to complete. You'll lie on the scanner while the technician places lightweight receiver coils on your body. During the process, you can relax, listen to music, or watch a show. Once complete, the 2,000 images captured are sent to a Prenuvo radiologist for a detailed evaluation. A detailed report of your results will be uploaded to your personal dashboard on the Prenuvo app within 5 business days.
At what age should I start whole-body MRI scans?
That’s a personal choice, as a whole-body scan at any age can be helpful. However, the incidence of cancer does increase with age, starting at around 40 years.
How does the Galleri testing work?
After you submit a request for a test through Extension Health, your Extension Health provider will request a test kit from Galleri. You will then schedule a blood draw appointment at Extension Health, and our medical team will coordinate shipping your sample to Galleri’s Grail Lab and coordinating your results review.
Can the Galleri test detect all types of cancer?
Clinical studies show the test can detect cancer signals across 50+ different types of cancer. But not all cancer types can be detected by blood samples.
Can Galleri assess future risk of cancer?
No. Galleri only detects cancer signals present at the time of the blood draw; the test cannot predict your future risk of developing cancer.
Who should consider the Galleri Test?
The test is recommended for adults with an elevated risk of cancer, including adults over the age of 50 as this age group is 13x more likely to have cancer than adults under age 50.
What does it mean if a cancer signal is detected?
This result means that the test detected a signal that could indicate cancer. About 1 out of every 100 tests has a Cancer Signal Detected result. This result will also include a prediction of the tissue type or organ associated with the cancer signal, called a ​Cancer Signal Origin (CSO). This provides direction to your doctor on the cancer’s origin and can help guide the next steps for diagnosis.
