Randy Cassingham gave a heads-up about this sort of technology on his page. Here’s some more of the same.
I may be looking into this, since having one form of cancer is no guarantee against developing another.
Fox Business:
Mayo Clinic developing blood test that can spot more than 50 types of cancer
Galleri, which is not covered by insurance, costs $949 and must be ordered by a licensed health care provider
…
Galleri looks for signals present in the blood stream that may be associated with cancer at the time of a blood draw.
The test uses next-generation sequencing and machine-learning algorithms to analyze methylation patterns of cell-free DNA (cfDNA) in the bloodstream, which can carry cancer-specific information. DNA methylation is a process used by cells to regulate gene expression. If a cancer signal is detected, Galleri will pinpoint where in the body the cancer is coming from to help health care providers determine the appropriate next steps for patient treatment.
