What have we learned?
• Our cancer incidence is low
• Maybe we are missing some cases
• Our priorities are different from others
• Saudi females have higher incidence than male: non-driving theory!
• We have regional variation; a call for research look
• We have no mortality data
• National survival data calls for improvement
• There is plenty of improvement to be done for SCR
