Huang Chuncais is healing very well from his last surgery. Doctors hope that he will be ready for his next operation within the next six months.

There are two main risks that accompany the next operation: the position of the tumor and blood loss. The tumor is currently positioned against his brain, making it difficult for doctors to perform the surgery. Due to the nature of neurofibromatosis, the tumor is clustered in several locations, like bundle of grapes, throughout his flesh.

The risk of rapid blood loss also poses a complicated problem.
