This is a mother's point of view, as we live and deal with our oldest child (16 years old) and his rare bone cancer, Metastatic Ewing Sarcoma diagnosis October 4, 2010. The cancer is in his right pelvic bone just below his hip joint and little tumors throughout his lungs. This journey of ours will last 7 - 9 months with Chemo, Surgery (to remove tumor in bone), radiation (lungs and possibly pelvic bone), and more Chemo.
