Nong Woonsen is suffering from a rare disease involving abnormal cells in her bone marrow.

Jan Cline, who was diagnosed with bone marrow cancer earlier this summer, told a TV channel that she could break a bone by merely walking.

To remedy the situation, bone marrow was extracted from Drake's hip and injected into the weakened part of his left leg fto make it more resistant.
