Bone tumour. Coloured X ray showing a tumour of the upper part of the tibia (shadowed area, lower centre). This is an osteoclastoma, or giant cell tumour (GCT). GCTs are rare, benign (non-cancerous) tumours. They normally occur in adults between 20 and 40 years of age. If not treated, the tumour will continue to grow and eventually destroy the bone. Surgical removal is the most effective treatment.
