I'm adding updates here so that I can easily keep folks in the loop, and also spend less time talking about this stuff! Diagnosis: Malignant fibrous histiocytoma (MFH) which has more recently been classified as pleomorphic undifferentiated sarcoma. REMINDER: Please don't bring up my medical situation with my grandparents. For now at least, I want to spare them the worry, especially since there are still unknowns. I hope those of you who know them will respect this request. Thanks!
