I have a rare cancer called neurofibroma sarcoma. what are the chances my kids can get it?

Possibility: Neurofibrosarcomas have a genetic basis with a possible abnormality in chromosome 17. Fifty percent of these tumors are associated with a familial condition known as neurofibromatosis, which causes tumors of nerve support cells (including Schwann cells). Resection of the tumor after possible shrinking is a consideration. The sarcomas in general tend not to respond well to chemo. Rather RT post op in the larger lesion is a consideration.
