Mayo Clinicians Explain the Options

摘要

If it is suspected that you have cancer, your doctor likely will order certain blood or other laboratory tests, such as an analysis of your urine or a biopsy of a suspicious area, to help guide the diagnosis, explains the staff at the Mayo Clinic, Rochester, Minn. With the exception of blood cancers, blood tests generally cannot absolutely tell whether you have cancer or some other noncancer-ous condition, but they can give your physician clues about what is going on inside your body.
