1.The test is typically done on a biopsy sample of the tumor. The sample is analyzed to identify genetic mutations or alterations that are associated with the tumor.

2.The test can help determine the most effective treatment options for the patient. For example, if a particular genetic mutation is present in the tumor, the patient may be eligible for a targeted therapy that specifically targets that mutation.

3.The test can also help predict how the tumor is likely to respond to different types of treatment. For example, if the tumor has a particular genetic alteration, it may be more or less responsive to chemotherapy or radiation therapy.

4.The test can help identify possible clinical trials that the patient may be eligible for. Many clinical trials are designed to test new targeted therapies or immunotherapies that are specifically aimed at certain genetic mutations or alterations.

5.The test can also help identify possible inherited genetic mutations that may increase the patient's risk of developing other types of cancer. If an inherited mutation is identified, the patient may be referred for genetic counseling and testing.
