A member asked:
Could i possibly have cancer and not know it? would there be detectable traces on cancerous dna in my blood?

Yes: This is the point of screening, to detect cancers in asymptomatic patients. There are new tests to look for cancer cells in the blood but these tests are still in the experimental phase.

Yes to both: You may have cancer and not know it. Cancer dna is probably present, but there are no easy, reliable, useful tests for detection.
