Mass is a quantity of material. Calcified is Organic tissue (Organ cells) that becomes hardened by the build up of lime and calcium salts (chemicals contained in the body and also are gotten through food intake)

So basically you have a lot calcium and lime chemicals that have found a place to build up and harden.

Kind of like a kidney stone - (calcium and lime hardened into a small pebble or stone in the kidneys) only for you this is on or near your overies.

So like kidney stones you will either be given medication and hope it desolves and or passes ( if its in the ovarian ducts or fallopian tubes and mobile it will move down the tube and out through your normal period cylces) or they will do surgery to remove it for you if it is attached to the organs.
