Translation Traps (for Russian speakers)
- Do not translate as 'шрам' or 'рубец', which are generic. The specific term is 'келоид' (keloid).

- Confusing it with 'hypertrophic scar' (which stays within wound boundaries).
- Using it as a general term for any bad scar.
- Incorrect plural: 'keloids' is standard, not 'keloidae' or 'keloidi'.

FAQ
Frequently Asked Questions
No, keloids rarely, if ever, regress spontaneously. They often require medical intervention for reduction or removal.
They are benign (non-cancerous) and not a direct threat to health, but they can cause significant physical discomfort, itching, pain, and psychological distress due to their appearance.
The exact cause is complex, involving an overproduction of collagen during healing. Risk factors include genetics, skin trauma (piercings, cuts, burns), and having darker skin pigmentation.
There is no single 'best' treatment; management is often multimodal. Common approaches include steroid injections, silicone sheets, cryotherapy, laser therapy, surgical excision (often combined with other treatments), and radiation therapy. A dermatologist or plastic surgeon can recommend the best course.
