Tyson was diagnosed in April 2011 at age 3 with a blood cancer called A.L.L. Acute Lymphoblastic Leukemia. His daddy was stationed in Iraq at diagnosis and served five more months. Now he is Tyson's number one buddy when Ty goes in for chemo and procedures. Ty has had some bumps in the road with a low immune system and infections but he is responding well to treatment so far and has about 1 1/2 years left of chemo. For more info on Ty you can read his blog HERE.
