No, we don't have the technology. Once cancer cells are systemic (metastatic), they can end up in bone or brain, where it can be extremely difficult to detect or treat. Cancer cells only need one rogue cell, and takes about 2 years to grow to a size that appears in tests.
Sadly, cancer can also mutate to avoid the PD-L1 pathway.
