Cause
Cancer pain may be caused by the cancer or by the
treatments and tests used. Cancer treatment does not always cause pain. But out
of every 10 adults with cancer, between 1 and 3 of them report having pain
caused by the treatment. Out of every 10 children with cancer, as many as 6
report having pain caused by treatment.1
Pain may also be caused by an infection, such as
shingles, that may develop because of the cancer or
its treatment. The kind of pain may vary depending on the cause. The first step
in managing your pain is understanding what is causing it.
Pain from the cancer itself can happen when:
- A cancer growth, or tumor, presses on bones,
nerves, or organs.
- Cancer cells spread to the bone and destroy
it.
- A tumor presses on the spinal cord, causing pain in the back,
legs, or neck.
- A tumor causes organs to swell or be blocked. For
example, a bowel obstruction can be caused by a tumor.
Because some cancer spreads far and fast, treatments have to be
strong. As a result, they often cause pain and other side effects that require
more treatment. Pressure on or damage to a nerve may cause tingling or burning.
Treatments such as surgery,
radiation, and
chemotherapy may also cause pain.
