Sometimes it does happen to kids, especially if there is a history of cancer on one or both sides of the family.
Back in junior high school, my class was assigned a book to read and review in English class. It was “Death Be Not Proud” by
John Gunther. written about 1949.
He describes the experience of watching his son eventually die from brain cancer. A rather serious book for 14 year olds, but we did as told and wrote our reports.
Made into a TV movie which I remember watching. To this day, every now and then that scene when he comes walking up the aisle to get his diploma or whatever was happening just gets to my heart.
