A cyst is a closed sac, with a distinct membrane and being separate from the surrounding tissue. It may contain fluids, soft-solid material or air. If it contains pus it is called an abscess, not a cyst. Usually cysts disappear with time, but sometimes need to be surgically removed. Cysts can form in or on all the major organs, in joints, breasts, eyelids and on the skin
Most cysts are benign, the result of plugged ducts or other natural body outlets for secretions. However, a few are associated with tumours and are potentially malignant
Iodine is the first remedy to try to remove cysts.
