Upper back pain is usually not a sign of cancer, since most cases are caused by muscles, joints, or posture. It can be a warning sign when pain persists, keeps getting worse, or appears with other symptoms that suggest something more serious. See common, non-cancerous causes of upper back pain and what typically helps.
Red flags that deserve prompt medical evaluation include unexplained weight loss, weakness or numbness in the arms, trouble walking, new bowel or bladder changes, or a known history of cancer. Pain that does not improve with rest or that lingers for weeks also needs assessment. Learn more about symptoms that may suggest cancer and when to seek care.
People who have had cancer should take new, persistent upper or middle back pain seriously, as some cancers can spread to the bones of the spine. When doctors suspect bone involvement, tests and imaging may be recommended to confirm the cause and guide treatment.
This information does not replace a medical visit. Persistent or worsening upper back pain should be assessed by a family doctor, who may refer to an oncologist or spine specialist if needed. Avoid self-medication with strong painkillers without guidance. Maintaining good posture and staying active can help prevent common mechanical back pain.
