"I'm really charmed to see his fighting spirit," Ganguly told reporters after spending more than half an hour with Sumit Kumar at the Tata Medical Centre where he is being treated for the past three months.
Ganguly gifted the boy an autographed bat, chocolates and a cake.
The programme was arranged by a Mumbai-based NGO that grants wishes of children suffering from life-threatening diseases.
"A wish fulfillment brings back what the illness takes away -- hope, strength and joy," the programme-incharge told PTI.
"We have engaged volunteers all over India and they find out the wishes of such children."
