2. Diagnosing a Sebaceous Cyst

A doctor may ask the patient when they first noticed the lump, what size it was when they spotted it and if the area hurts. The doctor will look for any bad-smelling drainage from the lump.

A visual exam usually provides enough evidence for a doctor to diagnose the lump as a sebaceous cyst. Still, any unusual signs may require additional tests to rule out cancer or other skin conditions, including an ultrasound to check the contents of the cyst and a punch biopsy, which removes a small piece of tissue.3‘Sebaceous Cysts: Treatment & Cause.’ Sebaceous Cysts, Cleveland Clinic, https://my.clevelandclinic.org/health/diseases/14165-sebaceous-cysts.
