Causes
of cancer pain
The two most common causes of cancer pain are the cancer itself and the treatments you receive
to treat cancer.
- The cancer itself. When cancer causes pain, some probable causes include the pressure of a
tumor on one of the body's organs or on bone or nerves. Sometimes cancer can cause pain when blood vessels
become obstructed by the tumor.
Cancer treatments. There are a variety of treatments for cancer and some of them are less
than pleasant. However, please remember that not all people being treated for cancer experience ALL of the array of
side effects of these treatments. A side effect one person feels may never happen to another. It is also very
important to remember that many treatment-related side effects can be successfully prevented in some cases, and
treated if they occur. More information about managing side effects is explained where each treatment type is
discussed.
Some examples of treatment-related pain include:
Chemotherapy can cause numerous side effects, depending in the medication
being used. Some of the more common side effects that cause pain include
mouth sores (mucositis), peripheral neuropathy (numb and sometimes painful
sensations in the feet, legs, fingers, hands and arms), constipation, diarrhea,
nausea, vomiting and abdominal cramps. Some people also experience bone and
joint pain from chemotherapy medications and from some medications used to
offset the impact of the chemotherapy on blood counts and on the risk of
infection.
Surgical treatments will, in some instances produce pain after they are
completed. Your physician and nurse will provide medications and techniques
to help you manage surgery-related pain.
Procedures related to cancer pain, such as biopsies, blood draws, lumbar
punctures, laser treatments, etc. can cause pain
No matter what the cause, most types of cancer pain can be managed with drug and non-drug
therapies. However, cancer pain is not always adequately managed. While competent health care professionals
should assume that people with cancer will need assistance to manage pain and ask you about it, if they do not, you
or your family members must speak up and insist on having your pain relieved. Some physicians may not always
prescribe the right medications or sufficient doses of the medication. If this happens, ask for more assistance and, if
you choose, ask that a pain specialist work with you to develop a plan to manage your pain. Pain specialists are
physicians and nurses who are experts in the field of pain management. For more information on finding a pain specialist, see
