Key clinical features used to differentiate between benign and malignant neck lumps in adults include:
- Age: Neck lumps in adults aged 45 and over are more suspicious for malignancy and warrant urgent referral for suspected cancer pathways NICE NG12.
- Persistence and unexplained nature: Persistent and unexplained neck lumps should raise suspicion of malignancy and prompt urgent referral NICE NG12.
- Size and growth: Lumps that are unexplained and increasing in size in adults are concerning for malignancy and require urgent investigation such as ultrasound within 2 weeks NICE NG12.
- Location: Supraclavicular or persistent cervical lymphadenopathy in adults aged 40 and over is more likely to be malignant and requires urgent chest X-ray to exclude lung cancer NICE NG12.
- Associated symptoms: Systemic symptoms such as fever, night sweats, weight loss, pruritus, shortness of breath, or alcohol-induced lymph node pain suggest lymphoma and warrant urgent referral NICE NG12.
- Consistency and fixation: Although not explicitly detailed in the provided context, malignant lumps are often hard, fixed, and non-tender, whereas benign lumps tend to be soft, mobile, and painless NICE NG12.
In summary, malignant neck lumps in adults are typically persistent, unexplained, increasing in size, located in high-risk areas (e.g., supraclavicular), associated with systemic symptoms, and occur in older adults (≥45 years), all of which should prompt urgent referral for suspected cancer pathways NICE NG12.
