If prostate cancer spreads to other parts of the body, it nearly always goes to the bones first (cancer.org/cancer/prostate-cancer/treating/treating-pain.html)





Osteoblastic lesions are associated with prostatic adenocarcinoma mets.

Most other cancer mets to the bone are osteolytic lesions.





Legend:

OB = osteoblastic

OC = osteoclastic/osteolytic

P=prostate, B=breast, K=kidney, T=thyroid, L=lung

my mneumonic: Lead Kettle

P------------B-------------K--------------T------------L

OB-------OB/OC------OC------------OC--------OC/OB

lilyo  @chandlerbas is this pneumonic in order of most common to least common, as in is prostate cancer the most common cause of metastasis to the bone regardless of wether the patient presents with osteoclastic or osteoblastic lesions? +
