Sebaceous cysts are common on the face, back, scalp and scrotum. Diagnosis of cysts All unusual lumps need to be investigated. Some cysts are cancerous and early treatment is vital. If left untreated, benign cysts can cause serious complications including: Infection — the cyst fills with bacteria and pus, and becomes an abscess.

If the abscess bursts inside the body, there is a risk of blood poisoning septicaemia. Peritonitis — if an internal cyst bursts, there is a risk of peritonitis, which is inflammation of the membrane lining the abdominal wall. Cancerous cysts If a cyst is cancerous, treatment will depend on its size and location and on whether or not cancer cells have spread to other parts of the body.
