Chances?

I will be applying to Northwestern for Early Decision; however, my unweighted gpa is about 3.1 because I had lymphoma (cancer) during my high school career. Based on 3.1 gpa with 34 ACT, do you think it is possible? I have outstanding activities, but I’m worried that I might get in due to my health condition.
