Cancer Pain

Pain in cancer may be caused by the tumor itself or by medical interventions in the diagnosis and treatment of the disease.

What are causes for cancer pain?

Pain may be caused by either treatment or the disease itself. Tumors can cause pain by irritating or damaging nerves. Radiotherapy and chemotherapy are examples of treatments that can sometimes produce significant pain persisting long after the disease has been cured. Approximately half of all cancer patients have pain. It is more common in the later stages of the disease.
