Why is managing pain important?

When pain is controlled, quality of life improves dramatically. Uncontrolled pain, on the other hand, creates unnecessary suffering, “not only by causing immediate physical suffering, but also by increasing the anxiety level and the fear about the future and future problems.”1Strang P. Existential consequences of unrelieved cancer pain. Palliative Medicine. 1997 Jul;11(4):299-305. 

Evidence shows that pain may affect survival, body terrainthe internal conditions of your body, including nutritional status, fitness, blood sugar balance, hormone balance, inflammation and more factors, symptoms, and side effects common among people with cancer. The way you manage stress, tension, and emotions can amplify or reduce your suffering related to pain. People often underestimate the effect that persistent pain has on quality of life, and so tend to “put up with it,” which can make things worse.

Connections to cancer survival

Cancer-related pain may increase mortality, although separating the effects of pain from the effects of advancing cancer and of pain medications on survival is difficult.

Better communication of pain and other symptoms may lead to improved survival among people with cancer.

Connections to body terrain factors

An imbalanced terrain can promote pain. Chronic inflammation, for instance, is directly related to pain processes. Pain can also affect terrain factors, such as suppressing certain immune functions and increasing risk for infection. We summarize evidence for these connections. We encourage you to work with a healthcare professional to assess terrain imbalances and create a plan to both balance terrain and manage pain.

High blood sugar and insulin resistance

Pain is linked to insulin resistance.

Hormone imbalance

Pain is linked to imbalances or disruption in stress hormones and sex hormones.

Immune function

Pain can suppress the immune system.

Inflammation

Preliminary evidencesignificant effects in small or poorly designed clinical studies OR conflicting results in adequate studies but a preponderance of evidence of an effect (this is the CancerChoices definition; other researchers and studies may define this differently) of higher systemic inflammation and poorer blood insulin levels among people with ovarian cancer with higher reported pain

Connections to symptoms and side effects

Probably no other symptom is connected to as many other cancer-related symptoms as cancer-related pain. Pain can affect your mood, your sleep, your energy, your nutritional requirements, your quality of life and ability to function, your stress, and your connection to others. In turn, many of these symptoms can affect your pain, as we illustrate in the graphic in the section “What approaches can help you manage pain?” We cannot stress enough how important it is to report all your symptoms to your doctor so they can help you manage them. You are not bothering them—you are not a complainer—you are a reporter. The very best care places improving your comfort and quality of life as important as treating your cancer.

Anxiety

Modest evidencesignificant effects in at least three small but well-designed randomized controlled trials (RCTs), or one or more well-designed, mid-sized clinical studies of reasonably good quality (RCTs or observational studies), or several small studies aggregated into a meta-analysis (this is the CancerChoices definition; other researchers and studies may define this differently) of higher levels of anxiety among people with cancer experiencing pain

Body composition or cachexia

Preliminary evidencesignificant effects in small or poorly designed clinical studies OR conflicting results in adequate studies but a preponderance of evidence of an effect (this is the CancerChoices definition; other researchers and studies may define this differently) of higher risk of needing nutritional interventions among people with newly diagnosed metastatic solid tumors and experiencing pain

Cardiovascular symptoms

Pain is linked to increased risk of cardiovascular events.

Depression

Modest evidence of a link between depression and pain among people with cancer

Fatigue

Modest evidence of a link between pain and fatigue among people with cancer

Quality of life and function

Modest evidence of a link between pain and worse physical function and quality of life among people with cancer

Sleep disruption

Modest evidence of more sleep disturbance among people with cancer experiencing pain

Stress or distress

Modest evidence of a link between distress or stress and pain among people with cancer

Symptoms not specific to cancer

Pain is linked to impaired gastrointestinal function.

Good evidencesignificant effects in one large or several mid-sized and well-designed clinical studies (randomized controlled trials (RCTs) with an appropriate placebo or other strong comparison control or observational studies that control for confounds) (this is the CancerChoices definition; other researchers and studies may define this differently) of higher incidence of severe sleep problems among people experiencing pain
