What causes cancer pain, and what do the symptoms depend on?
There are many causes of cancer pain, but it often happens when a tumor presses on nerves or organs, or when cancer cells invade bones or organs. Chemotherapy, radiation, or surgery also may cause pain.
The symptoms of cancer pain vary from person to person. The amount of pain may depend on the type of cancer, the stage or extent of the disease, and the person's pain threshold (tolerance for pain). Pain can range from mild and occasional to severe and constant.
