What criteria are considered for staging tumors?

How is tumor staging determined?

The clinical stage is an estimate of the extent of the cancer based on results of physical exams, imaging tests (x-rays, CT scans, etc.), endoscopy exams, and any biopsies that are done before treatment starts. For some cancers, the results of other tests, such as blood tests, are also used in clinical staging.

What is TNM staging in cancer?

Why would a doctor need staging information?

Doctors may recommend a local treatment, such as surgery or radiotherapy if your cancer is just in one place. This could be enough to get rid of the cancer completely. A local treatment treats only an area of the body.
