What does a hot spot on a bone scan mean?
An abnormal scan will show “hot spots” and/or “cold spots” as compared to surrounding bone. Hot spots are areas where there is an increased collection of the radioactive material. Cold spots are areas that have taken up less of the radioactive material.
Does a hot spot mean cancer?
Cancer mutations that are recurrently observed among patients are known as hotspots. Hotspots are highly relevant because they are, presumably, likely functional.
What does spot on bone mean?

What hot spots on a bone scan may mean?
Generally, there are two types of spots on a bone scan. Hot spots form when the radioactive material, or tracer, accumulates in areas of the bone.

Tumors and cancer can cause either type.
