(AP)-A Nebraska high school senior says he plans to walk across the stage at his graduation despite the return of an aggressive form of leukemia.

Malique Anderson is receiving treatment at Children’s Hospital & Medical Center in Omaha. The 17-year-old says the cancer has returned twice.

Malique says he tries to stay positive but he has tough days. He’s determined to walk across the stage at his graduation, and the upcoming event motivates him to receive treatment.

Malique’s parents say they are planning a bone marrow transplant. A dinner to raise money for his treatment is scheduled Saturday.
