When prostate cancer spreads, it often goes to the bones and causes a deep, constant ache that doesn’t get better when you move around.
Scientific Claim
Prostate cancer exhibits a predilection for osteotropic metastasis, resulting in persistent, non-mechanical bone pain that is present at rest and unresponsive to positional changes.
Original Statement
“Prostate cancer has this particular tendency for spreading to bone. It's one of the most common signs of metastasis in advanced prostate cancer and bone mets cause pain. Often described as a deep aching pain that is present at rest. It doesn't follow the pattern of mechanical back pain that improves with position or movement and it's persistent.”

Evidence from Studies
Supporting (1)
Effect of zoledronic acid on pain associated with bone metastasis in patients with prostate cancer.
The study didn’t test why prostate cancer causes bone pain, but it showed that men with this cancer do have serious bone pain — and that a drug can help reduce it. This means the pain is real and common, which supports the claim.
Contradicting (1)
One drug tried to stop the bone pain from prostate cancer — but it didn’t work at all. That makes us wonder if the pain is always as strong or consistent as the claim says, or if some types of pain just don’t respond to treatment.
Technical explanation
This study found sodium etidronate ineffective for relieving bone pain in prostate cancer patients — suggesting that not all bone-targeting agents work, and potentially implying that the pain mechanism may not be as straightforward or universally responsive as claimed, challenging the assumption of consistent, persistent pain.
