Causes of Cancer Pain
Pain can be due to various reasons related to the patient’s condition as well as from the treatment. It may be due to the growth of the tumor, causing the destruction of nearby tissues or organs.The tumor may be pressing against the nerves causing pain. The pain can also be due to chemicals released by the tumor or the way your body reacts to these chemicals. Side effects of treatment can also cause pain.
Management of Cancer Pain

- Location of the pain
- The severity of the pain
- If the pain is constant or intermittent
- Whether the pain is affecting your normal function and lifestyle
