Fever Checklist for People with Head and Neck Cancer

Fever in someone with head and neck cancer can signal an infection or a treatment-related complication, and certain signs mean you should seek urgent care right away. A practical, structured checklist helps you decide what to watch for at home and when to call or go to the emergency department. ^{[1] [2]}

---

Why this checklist matters

• Fever (100.4°F / 38.0°C or higher) in people receiving cancer treatment can be the first and sometimes only sign of a serious infection. ^{[1] [2]}
• Neutropenic fever (fever when white blood cells are very low) is an oncologic emergency and needs immediate antibiotics diagnostic tests should not delay treatment. ^{[3] [4]}
• After surgery or radiation in the head and neck, fever can also indicate wound or skin infection in treatment areas. Prompt contact with your care team is advised. ^{[5] [6]}

---

Immediate action thresholds

• Temperature 100.4°F (38.0°C) or higher measured once, or lower-grade fevers that recur within 1–2 hours. Call your oncology team or seek urgent care now. ^{[1] [2]}
• Fever with chills/shivering, feeling suddenly unwell, or fast heartbeat even if the temperature is not yet high needs urgent assessment. ^{[7] [1]}
• Fever during or soon after chemotherapy may be neutropenic fever and requires immediate antibiotics. Do not wait for symptoms to worsen. ^{[3] [4]}

At-home fever checklist

Use this list to document your symptoms before calling your care team; bring it with you if you go to urgent care or the ER. Check all that apply and note the time started. ^{[1] [2]}

1) Temperature and general symptoms

• Highest temperature today (°F/°C); how and when you measured it. ≥100.4°F/38.0°C is concerning. ^{[1] [2]}
• Chills, shivers, sweats, or shaking. ^{[1] [7]}
• Feeling markedly unwell, dizzy, or weak. ^{[7] [1]}
• Fast heartbeat or breathing, or shortness of breath. ^{[7] [1]}
• Headache or stiff neck. ^[1]

2) Respiratory and throat symptoms

• New or worse cough, sore throat, hoarseness, or trouble breathing. ^{[1] [8]}
• Mouth or throat sores, white or red patches, or ulcers that are not healing. ^{[1] [9]}

3) Treatment-site and skin checks

• Redness, swelling, increasing pain, drainage, or pus from a surgical incision. These changes with fever warrant a call now. ^[5]
• After head and neck radiation: new or worsening skin pain, blistering, moist skin breakdown, or oozing in the radiation field especially with fever or chills. ^[6]

4) Urinary and gastrointestinal symptoms

• Burning or pain with urination; bloody or cloudy urine. ^[1]
• Nausea/vomiting that does not improve; diarrhea or uncontrolled stools; new abdominal pain. ^{[7] [1]}

5) Oral and dental concerns

• Pain, swelling, or discharge in the mouth, gums, or jaw; nonhealing mouth sores; difficulty swallowing due to pain. ^{[1] [9]}

6) Cancer-treatment timing

• Date of last chemotherapy, immunotherapy, or targeted therapy; some medicines increase infection risk. ^[3]
• Recent white blood cell (neutrophil) counts if you have them; low counts raise urgency. ^[2]

7) Other red flags

• New rash. ^[1]
• Earache or new ear pain. ^[1]
• Any new focal pain that is severe or worsening. ^[1]

When to call your care team vs. go to the ER

• Call your oncology team immediately for any fever ≥100.4°F (38.0°C) or if you have chills, sweats, or suspected infection symptoms. ^{[1] [2]}
• Go to the emergency department now if you have:
  • Fever with shaking chills, shortness of breath, chest pain, confusion, fainting, or very fast heart rate. ^{[7] [1]}
  • Fever plus signs of wound or radiation-skin infection in the head/neck. ^{[5] [6]}
  • Fever within days of chemotherapy, especially if you’re known to have low white blood cells. ^{[3] [4]}

What to tell the clinician

Bring or share the items below for faster, safer care. This information helps decide about antibiotics and tests right away. ^{[3] [4]}

• Peak temperature and timing; antipyretics taken (acetaminophen, ibuprofen) and when. ^[1]
• Recent treatments (chemo, radiation, surgery), dates, and any central lines or feeding tubes. ^[3]
• Recent blood counts if available; prior neutropenia episodes. ^[2]
• All symptoms checked on the list above and when they began. ^[1]
• Drug allergies and current medicines, including antibiotics taken recently. ^[3]

---

Extra prevention tips

• Check your temperature if you feel unwell; do not mask fever with acetaminophen before discussing with your team unless you’ve been advised to. Early detection helps. ^{[1] [2]}
• Keep incision and radiation-treated skin clean and watch for redness, swelling, drainage, or increasing pain. Report changes early. ^{[5] [6]}
• Practice hand hygiene, avoid sick contacts, and maintain oral care to reduce mouth infections. ^[1]
• Know your clinic’s after-hours number; ask for written instructions about when to call and where to go after treatment. ^[3]

Quick-reference table: signs and actions

Situation	What it could mean	What to do now
Temp ≥100.4°F (38.0°C) once, or recurrent lower-grade fevers	Possible infection; if soon after chemo, possible neutropenic fever	Call your oncology team immediately; if after hours or no rapid response, go to ER
Fever + chills/shakes, fast heartbeat, shortness of breath, or feeling acutely unwell	Possible sepsis; urgent risk	Go to ER immediately; do not delay for tests
Fever + red, swollen, painful incision with drainage	Postoperative wound infection	Call team urgently; likely needs in-person assessment
Fever + radiation-skin blistering, moist breakdown, oozing	Radiation dermatitis with secondary infection	Call team urgently; consider in-person evaluation
Fever + urinary burning, cloudy/bloody urine	Urinary infection	Call team promptly for evaluation
Persistent fever after broad symptoms while counts may be low	Ongoing infection risk; needs evaluation and possible antibiotics	Seek urgent care; antibiotics should not be delayed if neutropenia suspected

References supporting temperature thresholds, infection signs, and urgency are consistent with standard oncology and infection precautions. ^{[1] [2] [3] [4]}

Special note on neutropenic fever

• In people getting cancer treatment, fever during neutropenia is treated as an emergency, with rapid antibiotics started before tests are complete. Risk tools guide who can be treated at home versus in hospital, but first doses should not be delayed. ^{[3] [4]}
• Your team may recommend preventive measures (such as growth-factor support) if your regimen has a moderate to high risk of febrile neutropenia. ^[3]

Post-surgery and radiation specifics

• After oral cavity surgery, fever or new redness/swelling or drainage from the incision warrants a prompt call to your surgical team. ^[5]
• During or after head and neck radiation, fever with skin breakdown, blistering, or oozing in the radiation field should be reported quickly. ^[6]

Bottom line

• Treat 100.4°F (38.0°C) as a call-now threshold, and combine it with the checklist above to spot urgent red flags early. ^{[1] [2]}
• If you recently had chemotherapy and develop fever, assume neutropenic fever until proven otherwise and seek immediate medical care. ^{[3] [4]}
• Early communication with your oncology team can prevent complications and improve outcomes. ^[3]
