70% of cancer deaths come from cancers with no recommended screening test. 🧬

That number stopped me cold when I read it in USA Today this week.

We talk a lot about improving lung cancer screening rates. About getting more people into the pipeline for the five cancers that already have established screening. And that work is urgent and necessary.

But 70% of cancer deaths are happening completely outside that pipeline.

This week, the FDA’s Molecular and Clinical Genetics Devices Panel voted in favor of GRAIL’s Galleri multi-cancer early detection blood test. The vote on whether benefits outweigh risks: 7 to 2, with one abstention. The safety vote was unanimous.

Here is what Galleri actually does:

🔹 It studies DNA fragments shed into the bloodstream, looking for tumor-specific markers
🔹 A single blood draw, with a prescription, at a cost of $949
🔹 In a study across 25,000 healthy adults over 50, it found cancer signals in 216 people, and 133 of them genuinely had cancer
🔹 It correctly predicted the cancer’s origin 92% of the time
🔹 The FDA’s final decision is expected in the coming months

That origin prediction matters. If the signal points to the pancreas, clinicians know exactly where to look next. That is not a small thing for a disease category that is historically caught far too late.

But here is the tension I sit with.

We already have screening tools that work. Low-dose CT for lung cancer. Colonoscopies for colorectal. Mammograms for breast. And we are still not getting them to the people who need them most. Screening rates in underserved communities remain unacceptably low for the cancers we already know how to find.

🔹 Adding a $949 blood test to the mix does not automatically close that gap.
🔹 Coverage is not guaranteed. Equity is not guaranteed.
🔹 The communities most likely to die from undetected cancer are the least likely to have a doctor who prescribes this test.

The Framework for What Happens Next:
1. FDA final approval decision, expected in coming months
2. Insurance and coverage negotiations across payers
3. Provider adoption and prescription behavior
4. Access and affordability in underserved populations
5. Integration with existing screening infrastructure

Save this if you work in screening policy, health equity, or oncology. Each of these steps is where the real fight happens.

A favorable FDA advisory panel vote is meaningful. It signals scientific credibility. But it does not move the needle on access by itself.

What changes outcomes is making sure this technology, and every other validated screening tool, reaches the people who have been historically shut out of early detection. That is the work. That is what keeps me building.
