I have had a painless lump in my neck for about 1 month. Ultrasound reports it as 18×11 mm with a "prominent fatty hilum." I also feel a separate firm area above my clavicle. What should I do?

A "prominent fatty hilum" on ultrasound often favors a benign/reactive lymph node, but imaging alone is not definitive. A firm, painless lump that has been present for a month, together with a separately felt supraclavicular (above the clavicle) lump, warrants follow‑up and possibly further tests. Continue with the planned 1‑month control ultrasound, but seek earlier review if any red flags appear: rapid enlargement, size over 2 cm, fixation to the skin, difficulty swallowing or breathing, night sweats, unexplained weight loss, or persistent fever. Take your ultrasound report and, if available, the images to your appointment. After clinical examination, the doctor may request a targeted neck or supraclavicular ultrasound, simple blood tests (e.g. CBC and inflammation markers such as CRP/ESR), and, if indicated, fine‑needle aspiration biopsy (FNAB) or advanced imaging. At home avoid pressing or squeezing the lump; keep a record of changes in size, firmness, pain, or skin appearance and, if helpful, take photos to show the clinician. Common specialties involved include Otorhinolaryngology, Internal Medicine, General Surgery and Radiology; Medical Oncology or haematology may be consulted if needed.
