The short answer to the question “Is back pain a sign of cancer” is, not necessarily. But it can be, especially if cancer is present in the colon, rectum, or ovary. A primary bone cancer tumor in the spine can be a source of back pain too, as can a number of cancers that spread to the back from other areas of the body. Back pain is also a common symptom of lung cancer. However, back pain that’s related to life-threatening diseases like cancer is rare. Odds increase as you get older, especially over age 55. But if you’re under 55, the chance that back pain is related to cancer is unlikely. One way to tell if cancer may be present is to be aware of other symptoms that typically occur in cancer cases. These include the following. * Feeling unusually weak or very tired. * Weight gain or loss with no known reason. * Changes in appetite and problems with eating, such as a hard time swallowing, indigestion or general discomfort after a meal. * Changes in bowel or bladder habits, such as difficult or painful urination, or blood in the urine or stool. * Nagging cough or hoarseness that doesn’t go away. * Abdominal pain. * Unexplained night sweats. * In women, change in breast size or shape. If you have any of these symptoms along with persistent back pain, be sure to see your doctor. Only a medical professional is qualified to diagnose the pain or symptoms you’re experiencing.
