Remission is when your cancer is no lomger active and there is no signs of activ cancer inside you. You are not considered "cured" until you have been cancer free or in remision for 5 years. This is a medical deffinition for cured so that ststistics use the same basis. Some of us that have been fighting for long times may not cosider ourselves cured at the 5 year mark as we will always worry about reoccurance and some people may consider themselves cured sooner.
