Can a physician can check a tumor to see if it is bi non or beligment?

Yes, a physician can check a tumor to determine if it is benign or malignant. This is typically done through imaging tests, such as MRI or CT scans, and by performing a biopsy, where a sample of the tumor is examined under a microscope. The characteristics of the cells and surrounding tissue will help the physician make an accurate diagnosis. Additional tests may also be conducted to assess the tumor's behavior and potential for spreading.
