question: Hi, my daughter went to the Dr. thinking she might have appendicitis and after an Xray, it was found she had a "lytic lesion with sclerotic border on her left iliac bone" according to the radiology report.  Her doctor she hasn't seen an orthopedic surgeon yet, she's at school UC Santa Cruz, is recommening an Nuclear Bone Scan...she is 20 years old, healthy, are we looking at cancer for sure? does a sclerotic border means is non agressive and slow growing but it could still be cancer? we don't know how long she had this..could it be many years? in that case, could it be the cancer spread? I'm desperate , I know I need to wait, but i just cant...thank you!
