12 tests are necessary.

The 12-item tumor test is necessary.

First, the 12-item tumor test can provide comprehensive tumor-related information. By detecting a variety of tumor markers, it is helpful to detect the presence or potential risk of tumors early, especially for screening some common tumors.

Second, in patients with established cancer, the test can help assess disease progression, treatment effectiveness, and monitor for recurrence or metastasis. This is critical for adjusting treatment options and timely intervention.

It can also help target surveillance in high-risk populations. For example, people with a family history, long-term bad habits or specific occupational exposure can detect abnormalities earlier and improve the chances of early diagnosis by regularly performing the 12-item tumor test.

Finally, this test also plays a role in clinical diagnosis and treatment decisions. Although the diagnosis of tumor cannot be determined solely by the results of tumor markers, combining clinical symptoms, imaging examinations and other aspects of information can provide doctors with a more comprehensive basis for judgment, so as to formulate more reasonable treatment strategies.
