About Pain | Cancer Pain
Over 1.5 million new cases of cancer were diagnosed in the United States in 2010 according to the National Cancer Institute, bringing the total number of Americans living with cancer to approximately 11.4 million. That same year well over 500,000 people died of the disease. For many survivors, pain is one of the unvarying constants in their lives. But it doesn't have to be that way.
Pain relief is a very important part of cancer treatment. Without pain relief, patients may find themselves unable to sleep, thus dibilitating themselves further. Without pain relief, patients may find themselves unable to keep up the strength of body and mind that are necessary for fighting the disease successfully.
Cancer patients generally suffer from three different types of pain:
Somatic pain can either be the result of sensory pain receptors located in the body's deep tissues or on the body's surface. With deep tissue pain, the patient cannot identify the exact source of the pain and experiences it as a constant, dull ache. Surface pain, on the other hand, is sharper and more intense; patients frequently describe it as having a "burning feeling."
Visceral pain is pain whose source is an internal organ such as the liver or the kidneys. Visceral pain can be caused by pressure secondary to a tumor, the stretching of tissue and muscles close to the organ, or by cancer cells that have invaded the organ itself. Patients generally describe visceral pain as a dull, throbbing pressure.
Finally there is neuropathic pain, the most uncomfortable pain of all. Neuropathic pain is caused by injuries to the neurons that transmit sensory signals. These injuries can be caused by pressure secondary to a tumor or a chemical injury secondary to cancer treatments like chemotherapy and radiation.
No patient should be required to live with pain. Cancer patients have the right to request and receive analgesic medication in sufficient amounts to control their pain. If your current regimen is not keeping your pain in check, then you must talk to your oncologist and other specialists about a new medication regimen that will be better able to control your pain. Many patients do not seek the pain treatment that would minimize their pain because they are afraid they will be prescribed substances to which they will become addicted. Studies have shown though that patients taking pain medication for legitimate reasons very rarely become addicted.
