As a parent of a 29 year old Ewings Sarcoma (bone) patient, I understand your anger and pain. After 14 cycles of chemo at a major cancer center, and some hope in Feb. this year, when he got a good 3 month post chemo checkup, there was hope. Unfortunately, after being back to work for only 2 weeks, my son woke up semi-paralyzed and 3 brain tumors were discovered. Six weeks after that, 2 new brain tumors were discovered. The sarcoma specialist told my daughter-in-law that Ewings Sarcoma rarely spreads to the brain. Unfortunately, in this case, it has. All our lives feel like a living nightmare. I am truly sorry for your loss. It certainly isn't fair.
