Why is appearance not enough?
Skin lumps can look similar despite different causes. An epidermoid cyst differs from one arising from a hair follicle or sebaceous gland. The label “sebaceous cyst” or a photograph is insufficient to identify the type or decide on removal.
When should you arrange an examination?
Arrange assessment for an unexplained lump, particularly if it grows, becomes hard and fixed, persists beyond two weeks or returns after removal. Breast or testicular lumps also need assessment. Do not wait two weeks if a lump is changing or worrying you.
Do not squeeze a painful or inflamed lump
Seek urgent assessment if a lump becomes painful or red. Do not squeeze or puncture it yourself, as infection may spread or scarring worsen. An infected lump may need treatment before removal is considered, and excision may be delayed until inflammation settles.
Does every cyst need surgery?
Cysts that cause no problems do not always need treatment. A clinician examines the lump and may request imaging or a sample if the diagnosis is uncertain. Intervention depends on the cause, symptoms and impact on daily life rather than treating excision as necessary for every lump.
What should you discuss if removal is proposed?
Ask about the diagnosis, reason for removal, alternatives, expected scar and chance of recurrence. Draining certain cysts is different from removing the whole cyst and recurrence can follow. Bring a list of medicines and supplements and mention previous inflammation or procedures in the area.
