Question 85 of 433

Are there cancer blood tests besides Galleri?

The short answer

Yes, and more are coming. None is FDA approved, and none has been shown to reduce cancer deaths.

A second multi-cancer test reached the market in September 2025 at about $690. Its maker reports higher detection for some of the deadliest cancers, at the cost of a higher false-alarm rate than Galleri’s. The trade-off between catching more and frightening more is the central question for this whole class. My advice in Part 16 applies to all of them.
