what causes a cyst?

Many kinds: A cyst is an abnormal, fluid-filled, epithelially-lined, closed structure -- a definition learned early by every medical student. There are hundreds of types, but the most familiar is the common epidermoid inclusion / "sebaceous" cyst under the skin. Privately i think many of these start with bug bites, but nobody's proved it. Cheers!

Calcified cyst: Are you referring to breast cysts with calcified walls? I'm not exactly sure, maybe some inflammatory reaction of the cyst wall. What I do know is that calcified cysts are a radiologist's best friend on mammography...easy to see, and 100% benign.
