Why do the analysis?
Mainly, for monitoring cancer, both from the point of view of response to treatment and possible recurrences; as an indicator of tumor mass (amount of tumor) and to establish the prognosis and stage the cancer; occasionally after a cancer screening test has been positive.
When to do the analysis?
