FAQ
Frequently Asked Questions
No, most cysts are benign (non-cancerous). However, some types or the cells within them can be pre-cancerous or cancerous, which is why medical evaluation is important.
A cyst is a closed sac, often with a defined wall, containing fluid or semi-solid material. A boil (furuncle) is an infected hair follicle filled with pus; it is an abscess, not a cyst, though some cysts can become infected and resemble boils.
Yes, many cysts are asymptomatic and are discovered incidentally during scans or examinations for other reasons.
No. Many cysts require no treatment if they are small, not causing symptoms, and are not suspicious for cancer. Removal is considered if they cause pain, grow large, rupture, or show concerning features.
