what if

we found cancer early enough to make a difference

Finding cancer early can improve survival

The earlier that cancer is diagnosed, the greater the chance of successful treatment and survival.1 Often, symptoms of cancer may not appear until later stages when treatment options may be more aggressive and less effective, and the chances of survival are lower.2

Introducing the Galleri test

The Galleri multi-cancer early detection test detects more than 50 types of cancer through a routine blood draw with a low false-positive rate of 0.5%.3

When a cancer signal is detected, the Galleri test predicts the origin of the cancer signal with high accuracy to help guide the next steps to diagnosis. Using the Galleri test alongside existing screening tools is expected to improve early cancer detection for patients at an elevated risk of cancer, such as those aged 50 or older.

Performance supported by large clinical studies

The Galleri test’s performance is supported by rigorous clinical studies with more than 20,000 participants representing diverse populations.3 – 5

  5. The PATHFINDER study is a prospective, multi-center study to evaluate the implementation of the Galleri test into clinical practice. A total of 6,662 participants without clinical suspicion of cancer have been enrolled with results returned to a study investigator. The study included men and women 50 – 79 years of age with and without a history of cancer.
