Your doctor may perform additional tests to determine if the cancer has spread and how fast it is growing.

• Bone Scan. Determines if cancer has spread to the bones. A safe, radioactive liquid is injected to help show whether cancer appears in the bones.
• CAT or CT Scan. Computerized Tomography. A series of X-rays that produce cross-sectional pictures of the body that may help your doctor see if the cancer has spread.
• Magnetic Resonance Imaging (MRI). MRI is like a CAT scan except it uses magnetic fields instead of X-rays to create detailed, cross-sectional pictures of selected portions of the body.
