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.
Symptoms of lung cancer can be like those caused by other diseases, such as chronic bronchitis or heart disease, and may at first be misdiagnosed, especially if there is a history of other health problems. One man who complained of low back pain was investigated for bowel, kidney, stomach and liver problems.
