Cancer staging is very important for planning the best treatment for that patient.
Staging helps describe where a cancer is located, if or where it has spread, and whether it is affecting other parts of the body. Doctors often use diagnostic tests to determine a cancer’s stage. Staging may not be complete until all of these tests are finished. Knowing the stage helps the doctor:
1.Plan treatment, including the type of surgery and/or whether chemotherapy or radiation therapy are needed
2.Predict the chance that the cancer will come back after the original treatment
3.Predict the chance of recovery
4.Talk about the diagnosis in a clear, common language with the entire health care team
5.Determine how well the treatment worked
6.Compare how well new treatments work among large groups of people with the same diagnosis
The doctors commonly use the TNM staging system for many types of cancers and according to the staging, they determine the viable treatment options for that particular cancer patient.
