Thunder Rookie Nikola Topic Diagnosed with Testicular Cancer — Prognosis “Extremely Positive”

Oklahoma City Thunder guard Nikola Topic has begun chemotherapy treatment after being diagnosed with testicular cancer, General Manager Sam Presti confirmed Thursday. The 19-year-old Serbian rookie underwent a biopsy earlier this month at MD Anderson Cancer Center in Houston, which confirmed the diagnosis.

The cancer was detected after a procedure at the start of training camp, and Topic chose to keep the news private until treatment began.
