Chronic Pain
Pain is a way our bodies tell us that something is wrong. Unexplained chronic pain in your body, such as in the joints, stomach, legs, behind the eyes, throat, stomach, or wherever you have pangs of pain is a sign that may indicate cancer. For instance, bone marrow cancer will often cause a pain in the bones that can only be explained as such. Another cancer that is often connected with chronic pain is lung cancer. 34% of lung cancer pain is caused for metastasis of lung cancer into the bones, the presence of a Pancoast tumor (located on the top of the lung near the brachial plexus nerves and cervical sympathetic nerves), or the spread of cancer into the surrounding chest wall.
Chronic pain persists for over 12 hours a day. Approximately 75% of all cancer patients suffer from chronic pain.
