Cancer Pain

Cancer pain refers to discomfort caused either by cancer itself or by its treatments. It may arise from tumours pressing on nerves, bones, or organs, or from side effects of surgery, chemotherapy, or radiotherapy.

What is Cancer Pain?

Cancer pain refers to discomfort caused either by cancer itself or by its treatments. It may arise from tumours pressing on nerves, bones, or organs, or from side effects of surgery, chemotherapy, or radiotherapy. Unlike other chronic pain conditions, cancer pain can change in character and intensity depending on the stage of the disease and the type of cancer involved.

While not every patient with cancer experiences pain, many do, and the severity can range from mild to debilitating. The good news is that with timely and appropriate management, most cancer-related pain can be effectively controlled, allowing patients to maintain comfort and dignity.

Cancer pain can vary in severity and form, affecting quality of life at every stage of the disease.

How severe can Cancer Pain be?

The pain can range from dull aches to severe, unrelenting pain that disrupts sleep, mobility, and emotional well-being. Pain severity often changes as the disease progresses. For some, it may be intermittent and manageable, while others may experience constant, worsening pain as tumours grow or spread.

Pain intensity does not always correlate with the cancer stage. Even early diseases can cause significant discomfort if nerves or sensitive structures are involved. That is why addressing pain promptly is essential to prevent it from becoming overwhelming.

How is the pain measured?

Describing pain can be difficult because it is such a personal and subjective experience. To help patients communicate their pain more clearly, doctors often use standardised tools. These scales provide a structured way to capture not just how strong the pain feels, but also how it affects daily life.

Some of the tools are:

  • Numeric Rating Scale (NRS 0–10) – patients are asked to rate their pain on a scale from 0 (no pain), 1 to 3 (mild pain), 4 to 6 (moderate pain, and 7 to 10 (worst pain). This simple measure helps track changes over time and evaluate how well treatments are working.
  • Brief Pain Inventory (BPI) – this questionnaire goes beyond intensity. It asks patients to describe where the pain is located, how often it occurs, and how it impacts activities such as sleep, walking, mood, and work. The BPI provides a more complete picture of how pain affects quality of life.

What are the types of Cancer Pain?

Cancer-related pain does not follow a single pattern. Its nature often depends on where the cancer is located, how it affects surrounding tissues, and whether treatments have caused additional discomfort.

This includes:

  • Somatic pain – aching, throbbing, or sharp pain from bones, joints, or muscles, often caused by tumours invading or pressing on these structures.
  • Visceral pain – deep, squeezing, or cramping pain from internal organs such as the liver, pancreas, or intestines.
  • Neuropathic pain – burning, tingling, or shooting pain resulting from tumour pressure on nerves, spinal cord involvement, or nerve damage caused by treatment.
  • Phantom pain – pain felt in a body part that has been surgically removed, where the intensity can be severe and perceived to be real
  • Referred pain – it is often perceived in one area while originating in another, such as a liver tumour may cause shoulder pain
  • Breakthrough pain – sudden, intense flare-ups of pain that occur despite ongoing treatment.

Visceral pain arises when cancer affects internal organs, often felt as cramping, squeezing, or dull discomfort that can be hard to pinpoint.

Does the stage of cancer affect pain?

As cancer progresses, the experience of pain can change. In the early stages, discomfort is often localised and may be easier to manage. As the disease advances, tumours may spread to bones, nerves, or internal organs, creating multiple sources of pain that are often more intense and persistent. Treatments such as surgery, chemotherapy, or radiotherapy may also trigger pain at any stage.

Addressing pain early is not only about comfort. It helps patients maintain mobility, cope better with treatments, sleep more soundly, and preserve emotional well-being. Pain relief is therefore considered an essential part of cancer care from the moment of diagnosis.

Generally, the typical patterns seen at different stages of the disease are:

Stage of Cancer Typical Features of Pain Impact on Daily Life
Early stage Pain may be mild to moderate, usually localised to the tumour site Often manageable with standard medication and allows daily activities
Intermediate stage Pain can spread or become more persistent, especially if tumours press on nerves or bones May interfere with sleep, work, and mobility
Advanced stage Multiple sources of pain from widespread disease, often more severe and constant Significant impact on quality of life and requires strong, tailored pain management strategies

How is Cancer Pain assessed in Singapore?

Cancer pain varies greatly in intensity, type, and underlying cause. As such, a thorough assessment is essential to guide effective management. Our doctors use a structured approach to understand your pain and its impact on daily living.

It usually involves:

  • Detailed history-taking – our doctor will ask about when the pain started, where it is located, and how it feels. This can range from sharp, dull, burning, or throbbing. They will also review your cancer type, stage, and treatment history to help identify possible triggers.
  • Physical examination – an examination is performed to check whether pain is linked to tumour pressure, bone disease, nerve involvement, or treatment side effects. Mobility, strength, and sensation are also assessed.
  • Pain scales and questionnaires – tools such as the Numeric Rating Scale or the Brief Pain Inventory are used to measure pain severity, frequency, and its effect on activities, sleep, and mood.
  • Imaging studies – depending on the symptoms, X-rays, computed tomography (CT) scans, or Magnetic Resonance Imaging (MRI) may be recommended to evaluate bone changes, tumour spread, or nerve compression.
  • Multidimensional assessment – since cancer pain can also influence mental health and social well-being, psychological and emotional factors are considered alongside physical symptoms.

How is Cancer Pain managed in Singapore?

Effective cancer pain management focuses on controlling symptoms, improving quality of life, and supporting emotional well-being. Treatment is personalised, depending on the type and severity of pain, cancer stage, and overall health.

It can be a standalone treatment or a combination of the following options:

Why is managing Cancer Pain important?

Living with cancer pain can be overwhelming. Beyond the physical discomfort, it can disturb sleep, make simple movements difficult, reduce appetite, and take a toll on emotional well-being. No one should have to endure this level of suffering.

With the right treatment, pain can be brought under control, allowing patients to rest better, stay active, cope more effectively with cancer therapies, and continue enjoying meaningful moments in daily life.
