There are several ways in which lung cancer can cause back pain. The tumor alone may contribute to back pain by creating direct pressure on structures in the back. Cancer may also irritate nerves traveling through the chest or the lining of the lungs which can be interpreted by the brain as back pain.
Back pain related to lung cancer is often described as pain occurring in the mid to upper back. 1  Unfortunately, back pain due to lung cancer can be very similar to other causes of back pain, and it is important to talk with your doctor if you are experiencing these symptoms.
