Is pain a common side effect of cancer treatment? How it’s managed

Pain can happen during cancer treatment, but it varies widely by person and type of therapy. Cancer itself can cause pain by pressing on nerves, bones, or organs, and treatments like surgery, radiation, and chemotherapy can also lead to pain, although not everyone experiences it. ^[1] Pain control is considered a core part of cancer care, and you have the right to ask for and receive treatment for cancer-related pain. ^[2] Everyone’s pain experience is different, ranging from mild and short-lived to severe or long-lasting, and it should be addressed early and continually during care. ^[3] Not all cancers cause pain, and even when pain occurs, the goal is to reduce it so it has minimal impact on daily life. ^[4]

Why pain occurs

• Tumors may invade or compress nearby tissues, releasing chemicals and triggering pain; treating the cancer can reduce pain in these situations. ^[1]
• Treatments can directly cause pain:
  • Surgery can produce postoperative pain at the operation site. ^[1]
  • Radiation can cause local tissue inflammation and nerve irritation. ^[1]
  • Chemotherapy can lead to neuropathic pain (nerve pain), such as tingling, burning, or sensitivity in hands and feet. ^[1]

How common is treatment-related pain?

Pain prevalence varies by cancer type and treatment. Many people report pain at some point, and undertreatment remains a documented problem; proactively reporting symptoms helps ensure adequate relief. ^[3] Early recognition, clear communication about type and severity, and combining medication with supportive therapies are effective strategies throughout and after treatment. ^{[5] [6] [7]}

Core principles of pain management

• Assess and communicate: Regularly rate your pain and describe its qualities (achy vs. burning, constant vs. intermittent). Early, accurate reporting guides the right plan. ^[5]
• Multimodal approach: Combining medicines with physical and behavioral therapies often works best and can reduce side effects. ^{[8] [5]}

Medication options

• Non‑opioid analgesics: Acetaminophen and NSAIDs can help mild to moderate pain, often as first steps. ^[8]
• Opioids: For moderate to severe cancer pain, opioids can be appropriate and effective when taken as prescribed, with careful monitoring to balance benefits and risks. ^[9] Opioids can be used safely under medical supervision, and doses are tapered when no longer needed to avoid withdrawal. ^[10] People receiving cancer care rarely use opioids outside pain control when guided by their team. ^[11]
• Neuropathic pain treatments: Duloxetine is considered a first‑line option for chemotherapy‑induced peripheral neuropathy; other options may include gabapentin, pregabalin, tricyclic antidepressants, and topical therapies. [PM18]
• Adjuvant therapies: Depending on the cause, steroids, nerve blocks, or topical agents may be added to reduce inflammation or nerve pain. ^[1]

Non‑pharmacologic therapies

• Physical medicine and rehabilitation: Exercise, stretching, manual therapies, bracing, and assistive devices can reduce pain and improve function with minimal side effects. ^[12] These patient‑controlled modalities are commonly beneficial even if not explicitly tested in all cancer settings. ^[13]
• Behavioral approaches: Relaxation training, mindfulness, pacing of activities, and cognitive strategies can meaningfully reduce pain’s impact and improve quality of life. ^[8]
• Education and self‑management: Understanding triggers and planning daily activities support pain control during and after treatment. ^[5]

Special situations

• Post‑surgical pain: Typically short‑term and managed with a stepwise plan; persistent pain may require specialized nerve pain treatments or physical therapy. ^[1]
• Radiation‑related pain: Local skin or tissue irritation may respond to topical care, anti‑inflammatory strategies, and targeted rehabilitation. ^{[1] [12]}
• Chemotherapy‑induced peripheral neuropathy (CIPN): Nerve pain can affect up to a substantial portion of people on neurotoxic agents; duloxetine has the strongest evidence, and home‑based walking and resistance exercises can reduce symptoms. [PM18]

Safety and monitoring

• Regular review: Pain plans should be adjusted over time to match changing symptoms and goals, especially as treatments progress or end. ^[5]
• Opioid stewardship: For those no longer in active treatment (survivorship), clinicians consider unique risk‑benefit factors; nonopioid therapies are preferred for chronic pain when benefits outweigh risks, and opioids are considered when necessary with close monitoring. ^{[14] [8]}

What you can do

• Tell your team promptly when pain starts or changes; don’t wait until it’s severe. Timely management improves outcomes. ^[2]
• Keep a simple pain diary (intensity, triggers, relief with treatments) to personalize your plan. ^[5]
• Ask about layered strategies: medications plus movement, relaxation, and practical supports like braces or cushions. ^{[12] [8]}
• Discuss goals: reducing pain to enable sleep, movement, and daily activities is a practical target even if full relief isn’t immediate. ^[4]

Key takeaways

• Pain can be a side effect of cancer treatments, but it is manageable with a tailored plan. ^{[1] [2]}
• You have options from non‑opioid medicines and rehab therapies to targeted neuropathic treatments and, when needed, carefully managed opioids. ^[8] [PM18] ^[9]
• Early reporting and a multimodal approach help control pain and protect quality of life during and after treatment. ^{[5] [8]}
