Germ cells, such as testicular cancer and ovarian cancer.
Analysis of tumor cells in circulation. Newly developed blood tests are used to detect cells that have detached from the original site of cancer and circulate through the bloodstream.

This analysis is not usually used in clinical settings.
While blood and urine tests can help give clues to the doctor, other tests are usually needed to reach the diagnosis. For most forms of cancer, it is generally necessary to perform a biopsy (a procedure to obtain a sample of suspicious cells for analysis) to arrive at a definitive diagnosis.
In some cases, the indexes of tumor markers are controlled over time. The doctor may schedule a follow-up analysis in a few months. Tumor markers are very often useful after receiving a diagnosis of cancer. The doctor can use these tests to determine if the tumor responds to treatment or if it is increasing in size.
In most cases, after finishing cancer treatment, the use of blood tests is not useful to discover if cancer returns. Analyze the specific aspects of the type of cancer you have with the doctor.
