Cancer Pain and Palliative Care

—

In one line

·Cancer pain is not just one thing — it hurts the body, the mind, the spirit, and the connections people need to feel whole.

—

Normal physiology

·Normally, pain is a helpful alarm that warns you when tissue is being damaged so you can protect yourself and heal. Once you remove the danger — like moving your hand off the stove — the pain stops. That quick on-off signal keeps you safe without wearing you out.

What goes wrong

·In cancer, the normal pain alarm gets stuck 'on' because the tumor keeps growing, pressing, and damaging tissue without stopping. On top of that, treatments meant to fight the cancer — like chemotherapy and radiation — can hurt nerves and normal tissues too. The body also loses weight, strength, and hope, which makes every pain feel worse. So three things break at once. First, the tumor itself hurts by invading bones and squeezing organs (somatic and visceral pain). Second, the tumor or treatments damage nerves directly, so they misfire and send burning or shooting signals even when nothing new is hurting them (neuropathic pain). Third, the constant suffering, fear of death, loss of independence, and loneliness pile on top of the physical pain and make it feel unbearable (psychosocial and spiritual pain). Together, these three create what is called 'total pain' — a hurt that involves body, mind, heart, and spirit all at once.

Red flags · escalate now

·New, severe pain that suddenly starts or gets much worse over hours or days
·Numbness, tingling, or weakness in the arms or legs, or loss of bowel or bladder control (may mean the spinal cord is being squeezed by tumor or collapsed bone)
·Trouble breathing, chest pain, or coughing up blood (may mean a clot in the lung or cancer spread to the lungs)
·Confusion, severe headache, or sudden trouble speaking or moving one side of the body (may mean cancer has spread to the brain or bleeding inside the skull)
·Fever above 100.4°F (38°C) with chills, especially if the person is on chemotherapy (the immune system may be too weak to fight infection, risking sepsis)

—

Workup

·Complete blood count (CBC) with differential
·Basic metabolic panel (BMP): sodium, potassium, creatinine, calcium
·Liver function tests: AST, ALT, bilirubin, albumin
·Plain X-ray of the painful bone (e.g., spine, hip, femur)
·MRI of the spine with and without contrast (if any red-flag neuro symptoms: leg weakness, numbness, or bladder/bowel trouble)
·Urinalysis and urine culture (if burning with urination, fever, or new confusion in a patient on opioids)
·Chest X-ray (if new cough, shortness of breath, or chest pain)
·Pain assessment using a validated scale: numeric rating scale (0–10), PAINAD scale for patients who cannot speak, or Edmonton Symptom Assessment System (ESAS)

—

Treatment

·Assess pain type, location, and severity using a standardized tool (numeric scale 0–10, PAINAD for non-verbal patients, or ESAS); separate nociceptive (bone/organ) pain from neuropathic (nerve) pain from psychosocial/existential suffering
·Start non-opioid analgesia: acetaminophen 650–1,000 mg every 6 hours (max 3 g/day if liver is healthy, max 2 g/day if liver disease or alcohol use) for mild pain, or NSAID (ibuprofen 400–600 mg every 6–8 hours, naproxen 250–500 mg twice daily) for bone pain if kidneys and stomach are healthy
·Add adjuvant medicine for neuropathic pain: gabapentin starting 100–300 mg at bedtime, titrate up every 3–7 days to 300–600 mg three times daily (max 3,600 mg/day); or duloxetine 30 mg daily, increase to 60 mg after one week; add dexamethasone 2–4 mg daily if nerve compression from tumor swelling
·Titrate opioids using the WHO analgesic ladder: start with weak opioid (tramadol 50 mg every 6 hours or codeine 15–60 mg every 4 hours) for moderate pain; escalate to strong opioid (morphine, oxycodone, hydromorphone, or fentanyl patch) for severe pain, using long-acting formulation for baseline pain plus short-acting for breakthrough pain; titrate dose every 24–48 hours based on pain scores and side effects
·Start bowel regimen prophylactically before opioid-induced constipation begins: senna (stimulant laxative) 2 tablets (17.2 mg) at bedtime plus docusate (stool softener) 100 mg twice daily, or polyethylene glycol (PEG 3350) 17 g daily; titrate laxatives up as opioid dose increases; add methylnaltrexone 12 mg subcutaneous every other day or naloxegol 25 mg daily if refractory
·Screen for depression, anxiety, and existential distress using simple questions ('How is your mood?' 'Are you worried or scared?' 'Do you feel like a burden?' 'Do you have thoughts of hurting yourself?'); offer counseling, chaplaincy, support groups, or cognitive-behavioral therapy; consider antidepressant (duloxetine 30–60 mg daily also treats nerve pain, or mirtazapine 7.5–15 mg at bedtime also helps nausea, appetite, and sleep)
·Involve palliative care team early (at diagnosis of advanced cancer, not just at end of life); consider radiation therapy for painful bone metastases (single 8 Gy dose or 20–30 Gy in fractions over 1–2 weeks), nerve blocks (celiac plexus block for pancreatic cancer pain, intercostal block for rib pain, epidural or intrathecal block for lower-body pain), or intrathecal pain pump for refractory pain uncontrolled by maximum oral/transdermal opioids

NCLEX trap

·First ask what kind of pain this is. Nerve pain (burning, shooting, tingling) needs gabapentin or duloxetine — medicines that calm overactive nerves. Sadness or fear (psychological pain) needs counseling and sometimes antidepressants. Bone pain (aching, worse with movement) responds to NSAIDs (drugs that stop inflammation, like ibuprofen) plus opioids. Start with acetaminophen or ibuprofen, then add the medicine that matches the pain type. Jumping straight to strong opioids can slow breathing, cloud thinking, cause severe constipation, and miss the real upstream break — you treat the symptom but ignore the cause.
·Cancer pain has four parts: body (the tumor pushes on tissues, invades bone, presses on nerves), mind (fear, sadness, worry about dying), social (family stress, money worries, feeling like a burden), and spirit (what does this all mean? why me?). If you fix only the body pain, the other three kinds still hurt. Screen for depression, anxiety, and spiritual distress at every visit — use a tool like the Distress Thermometer (NCCN guideline) or ask open questions: 'What worries you most?' 'What gives your life meaning?' Refer to social work, chaplaincy, and psychology as part of the team.
·Start palliative care the day you diagnose serious illness — cancer, heart failure, COPD, kidney failure. Palliative care runs alongside curative treatment; it is not 'giving up.' It focuses on comfort, quality of life, and helping patients and families understand choices. Studies (NEJM 2010, Temel et al.) show patients with metastatic lung cancer who got early palliative care lived longer (11.6 months vs. 8.9 months) and had better quality of life than those who got standard oncology care alone. ASCO and NCCN guidelines recommend concurrent palliative care for all patients with metastatic cancer or high symptom burden.
·Match the medicine to the pain type. Bone pain (aching, gnawing, worse with movement) responds to NSAIDs (ibuprofen, naproxen — they stop bone inflammation) plus opioids. Nerve pain (burning, shooting, feels like electricity or pins and needles) needs gabapentin, pregabalin, or duloxetine — drugs that calm the firing of damaged nerves. Visceral pain (deep, cramping, vague, hard to pinpoint — like from a swollen liver or blocked bowel) needs opioids. Always assess pain character, location, what makes it worse, and what makes it better before choosing a drug. Use the OPQRST mnemonic: Onset, Provokes/Palliates, Quality, Region/Radiation, Severity, Time.
·Sleepiness (sedation) usually fades after 3 to 5 days as the body adjusts to the opioid. Constipation never goes away on its own — every patient on opioids needs a bowel regimen from day one: a stimulant laxative (senna or bisacodyl — they make the bowel squeeze) plus a stool softener (docusate — it adds water to the stool). These side effects mean you need to manage them, not stop the pain control. If sedation persists beyond 5 days or worsens, then reassess the dose or switch to a different opioid (opioid rotation). Monitor respiratory rate; if it drops below 8 breaths per minute or the patient is hard to wake, hold the opioid and consider a small dose of naloxone (0.04 mg IV, given slowly to reverse sedation without stripping all pain relief).
·Screen every cancer patient — especially lung, breast, prostate, renal, and multiple myeloma (these spread to bone often) — for new back pain, new leg weakness, numbness in a band around the chest or belly, or new bowel or bladder problems (cannot urinate, leaking stool or urine). Spinal cord compression is an oncologic emergency; untreated, it destroys motor function in hours and can leave the patient paralyzed. If you suspect it, get an MRI of the whole spine within hours (not just the painful spot — 20% have compression at multiple levels) and call oncology immediately for urgent dexamethasone 10 mg IV (a steroid that shrinks swelling around the cord) and arrange radiation or surgery. Time is spinal cord — every hour counts.
