@erasahai, thank you for explaining more of your son's diagnosis and treatments. I modified the title of your discussion and moved it to the Cancer group here: https://connect.mayoclinic.org/group/cancer/

I did this to connect you will other members who have experience with Ewing Sarcoma, like @mgashaj @kristennursepatient @madstrong @suzanneb and @erikahamilton.

It must be a blow to you, your son and your whole circle of family and friends when you heard the cancer had come back. I can imagine that you're anxious to know what the future may hold. It must be additionally challenging to be getting treatments in this time of COVID-19. Does your son like to have you accompany him to treatment? Does the hospital allow family members?
