Thyroid swelling: warning signs, cancer risk, and evaluation

Most thyroid swellings are not cancer, but selected features such as rapid growth, pressure symptoms, suspicious ultrasound findings, or abnormal cytology warrant closer attention.

Evaluation is based on clinical examination, ultrasound correlation, and additional testing before deciding whether observation, repeat testing, or surgery is most appropriate.

Patients benefit from understanding that thyroid cancer risk is judged through a combination of findings rather than by swelling size alone.
