* Have had ≥ 1 UC visit

Exclusion Criteria

For Galleri + UC (Galleri-Tested Arm):

* Evidence of having had a previous MCED test (including but not limited to the Galleri test, e.g. CancerSeek, PanSeer). Participation in a study such as GRAIL's STRIVE study where results were not returned is not an exclusion criterion.
* Undergoing clinical evaluation for suspicion of cancer within 6 months prior to enrollment. Personal history of hematologic malignancy and/or invasive solid tumor (excluding non-metastatic basal cell carcinoma and squamous cell carcinoma of the skin):

* Evidence of having had a previous MCED test (including but not limited to the Galleri test, eg.CancerSeek, PanSeer). Participation in a study such as GRAIL's STRIVE study where results were not returned is not an exclusion criterion.
* Undergoing clinical evaluation for suspicion of cancer.
* Personal history of hematologic malignancy and/or invasive solid tumor (not including non-metastatic basal cell carcinoma and squamous cell carcinoma of the skin):

1. Diagnosed ≤3 years before expected enrollment date and/or
