Per a release, Farmer had been feeling sick for one week and paid a visit to the Ohio State team doctor on Monday, thinking that he was suffering from mononucleosis. Those tests came back negative but revealed abnormalities that led to further testing and the eventual diagnosis. The team was informed of the diagnosis on Tuesday night and Farmer will begin treatment on May 5.
"We are fortunate here at The Ohio State University to have The James Cancer Hospital and some of the best leukemia and oncology doctors in the world," Ohio State head coach Greg Beals said in a video statement. "Zach is in very good hands. I met with Zach this morning and he is in good spirits in the company of family, friends and teammates. Zach is strong and otherwise healthy and is a great candidate to beat this diagnosis.
"An aggressive treatment regimen will start Monday. We ask that the strength of Buckeye Nation be behind Zach and his family throughout this treatment process. The team as a whole is obviously concerned about their brother, but we will forge on in our mission. Thank you, and go Bucks."
