Cancer Pain: Symptoms, Assessment and Support

Cancer pain can come from a tumour, treatment, or another health problem and deserves careful assessment.

It may feel aching, sharp, burning, cramping or like pressure. Pain can affect sleep, movement, appetite, concentration and mood, but support can be tailored to the type of pain and what matters most to you.

Pain related to cancer can be constant or intermittent and may change with position, activity or time of day. Persistent bone pain is a very common presentation of cancer pain, while persistent abdominal pain is also a common presentation. New severe pain, pain with weakness, numbness, confusion, breathlessness, fever or difficulty passing urine or stool needs prompt medical attention.

A tumour can press on or grow into bone, nerves, organs or other tissues. Cancer treatments can also cause pain, for example after surgery or when nerves are irritated. Constipation, infection, muscle strain and unrelated conditions may contribute, so new pain should not automatically be assumed to have one cause.

Pain may fluctuate as the underlying illness, treatment and daily activity change. Keeping a short record of pain intensity, breakthrough episodes, medicines and side effects gives the clinical team practical information for adjusting a plan.

Pain can occur when cancer involves sensitive structures such as bone, nerves or organs. Previous procedures, treatment-related nerve changes, reduced mobility and long periods in one position can add to discomfort. These factors do not predict an individual experience.

Assessment starts with your description of the pain, medicines and medical history. A clinician may examine the painful area and check strength, sensation, movement and tenderness. Blood tests or scans may be considered when they would clarify a cause or change management.

Treatment may combine regular pain medicine, medicine for breakthrough pain and support for symptoms such as nausea or constipation. Physical approaches, comfortable positioning, gentle movement and emotional support can be useful alongside medicines. If a tumour is causing a local painful area, palliative radiotherapy may be discussed. Cancer pain management and palliative care focus on comfort, function and your priorities at any stage of illness.

Take medicines as prescribed and tell the team if relief fades before the next dose or side effects interfere with daily life. Plan demanding activities for times when pain is better controlled, accept practical help and use a symptom diary. Pain can be distressing; discussing worry, low mood or sleep disruption is part of good care.

Your oncology team can coordinate with pain, palliative-care, rehabilitation and mental-health professionals. Seek urgent assessment for sudden severe pain or pain accompanied by new neurological symptoms, breathing difficulty or marked drowsiness.
