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.
Re: what does lung pain/cancer feel like. I presume you mean where would the pain be if your lungs were hurting. The pain can be anywhere from the front of your chest behind your ribs to your upper back or shoulders. The pain is usually exacerbated by taking deep breaths.
