The Majority of Patients With Advanced Breast and Prostate Cancer Are Likely to Get Bone Metastases

SREs Are Clinically Significant and Serious Consequences of Bone Metastases

SREs Are Both a Common and Frequent Problem for Patients With Advanced Cancer Untreated for

Bone Metastases

Yes



Probably, at least in patients with renal

Maybe

Should YOU use it routinely in your patients with solid

tumors ?
