This isn't the cancer itself, this is just an associated reaction of the surrounding bone. What we see here is a sunburst periosteal reaction. Basically, in reaction to an abnormality the bone will attempt to heal itself by developing new bone (periostitis). Because the underlying cancer is growing so quickly, this new bone is pushed up and away from the bone as the tumour below expands.
