I've had a lumpectomy for invasive ductal carcinoma, tumor 2.0cm. nodes 3 of 16 positive. Tumor characteristics: "aggresive", nuclei activity 3. angiolymphatic +. Extranodal involvement +. Tumor was self discovered and missed on annual mammos. Breast tissue "dense". Should I ask for a bone scan before chemo starts? If she says no, do you have suggestions for an encouraging arguement? Please advise asap. thanks!
