As part of the diagnostic process you may be expected to
undergo additional tests to determine if cancer has spread
beyond the prostate. This may include a bone scan.
A bone scan (shown at left) is an imaging technique
used to identify the presence of cancer in the bones.
A tiny amount of radioactive substance is injected
into your bloodstream and absorbed by your bones. If
prostate cancer has spread to the bones, it most often
shows up on the scan as a series of hot spots (darker
areas) along the spine and ribs.
