Back, Hip, or Bone Pain: When to Get Checked
The short answer
Back, hip, and bone pain are among the most common complaints there are, and cancer is a rare explanation for them. The National Cancer Institute states the general rule for any worrying symptom: cancer can cause many symptoms, "but these symptoms are most often caused by illness, injury, benign tumors, or other problems."
Cancer that starts in bone is rarer still. The NCI reports that primary bone cancer "is rare. It accounts for much less than 1% of all new cancers diagnosed."
That is the honest background. It does not mean pain should be ignored. The NCI is equally clear on the other side: "Persistent or unusual pain or swelling in or near a bone can be caused by cancer or by other conditions," and "It is important to see a doctor to determine the cause of any bone symptoms."
Two different things called bone cancer
Doctors mean two different things by cancer in bone.
Primary bone cancer starts in the bone tissue itself. This is the rare one.
Metastatic bone cancer is cancer that began somewhere else in the body and spread to the bones. The NCI notes that "cancer that metastasizes (spreads) to the bones from other parts of the body is called metastatic (or secondary) bone cancer." Among the symptoms the NCI lists for metastatic cancer are "pain and fractures, when cancer has spread to the bone."
The NCI also notes that "metastatic cancer does not always cause symptoms," and that when symptoms do appear, "what they are like and how often you have them will depend on the size and location of the metastatic tumors."
The pattern that gets more attention
Pain is the most common symptom of bone cancer, though not every case causes it. The features the NCI describes as worth a doctor's attention are:
- pain in a bone or joint that is persistent or unusual
- swelling in or near a bone, or swelling over a bony part of the body
- stiffness in a joint
- pain in the arm when lifting
- a limp or new difficulty walking
- a lump
- unexplained fever
- a bone that breaks for no known reason
That last one carries weight. A bone that fractures without a fall or injury to explain it is not a normal event.
The NCI adds the sentence that matters most here: these symptoms "may be caused by osteosarcoma, UPS, or other problems. The only way to know is for your child to see a doctor." The same logic applies to adults. A symptom list cannot sort this out. An exam can.
When to make the appointment
The NCI's timing guidance for symptoms generally: "If you have symptoms that do not get better after a few weeks, see your doctor so that problems can be diagnosed and treated as early as possible."
For bone pain, a few practical readings of that:
- Pain that has lasted more than a few weeks without improving deserves an appointment, even if it is mild.
- Swelling near a bone, a lump, or unexplained fever alongside the pain moves it up the list.
- A bone that breaks with little or no force is a reason to be seen promptly, not to wait out a few weeks.
- If you have been treated for cancer before, tell whoever you see. That history changes how new bone pain is evaluated.
What happens at that appointment
Expect a conversation and an exam first. If your doctor wants to look further, the NCI lists these tools for evaluating bone symptoms:
- X-ray — usually the first image of the painful area
- CT scan, MRI, bone scan, PET scan, or angiogram — for a more detailed look at the bone and surrounding tissue
- Blood tests — including levels of alkaline phosphatase and lactate dehydrogenase, two enzymes that can be raised in bone disease
- Biopsy — removing a tissue sample from a bone tumor "to determine whether cancer is present"
A biopsy is the only test that answers the cancer question directly. Most people evaluated for bone pain never reach that step, because the x-ray and exam explain what is going on.
Questions worth asking
- What do you think is causing this pain?
- Does anything about my exam or history change the urgency?
- Should we image it now, or wait and see how it behaves?
- If this does not improve, when should I come back?

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status: Source verified — This page was created with AI assistance and checked against the sources listed on it. Source checking is not a medical review.
Human medical review: not completed. Cancer Explained is not clinician-reviewed, and that is a deliberate design choice rather than a gap we are waiting to close. We restate published federal guidance and cite it; the authority belongs to the source, not to us. That is why every page names where its claims come from — so you can verify us instead of trusting us. Use it to understand your situation and to ask better questions of the people treating you.
