The Denver Nuggets have reported that a testicular tumor removed from Nene was malignant.

The team said on Tuesday that the tumor was discovered early, and that medical tests showed the cancer was isolated.

"The recovery rate is extremely high," the Nuggets said in a statement. "In addition, the odds of a recurrence are very small."

The Brazilian player underwent surgery January 14 to remove the tumor. The team said he was doing well, but there was no timetable for his return.
