What causes sebaceous cysts or how can you keep from getting them.

Blocked gland: A sebaceous cyst is a collection of oily fluid that occurs when an oil gland is blocked. Some folks are more prone to them than other and they often appear on the neck, shoulders, and back. Try to avoid skin products that are oily. I would also stay away from transfats and bad oils, which is good for overall health. Saunas and sweating may help a bit although i don't of data.

Depends: Sebaceous cyst is an old term still used by drs who know little about them. Are they acne cysts? Tricholemmomas? The most common are intradermal inclusion cysts. Can occur almost anywhere, most often scalp, back, buttocks. May be multiple. Strong genetic factor. Not you fault. Easily removed by dermatolopgist or surgeon.
