Tests used to diagnose and stage breast cancer include:
• Blood tests
• Advanced imaging tests, including: Computed tomography (CT) scans, which use low-energy X-rays to produce 3D images of tissues and organs; Bone scans, which use a radioactive tracer that can highlight areas of cancer; Magnetic resonance imaging (MRI), which uses a strong magnet to produce detailed pictures of organs and other parts of the anatomy; Positron emission tomography (PET) scans, which use a radioactive substance to uncover cancer cells in the body
• Biopsies, which are procedures to remove small tissue samples of your tumor
