The Ewing sarcoma cases coincide with Post-Gazette findings that nine Canon-McMillan preschoolers and students during the 2018-2019 school year also had cancer and mostly rare types. Those cases include two cases each of osteosarcoma (bones) and leukemia (blood), and one case each of liposarcoma (connective tissue), rhabdomyosarcoma (soft tissue), neuroblastoma (nerve cells), liver cancer and Wilms (kidney) tumor.
