Ovarian Cysts: These occur in two forms, namely "functional" and
"organic". <Symptoms may not be present but can include pressure or pain
in the abdomen, problems with urine flow or pain during sexual
intercourse. Rarely, a very large cyst can become twisted and stop its
own blood supply, possibly causing nausea, fever or severe abdominal
pain. Functional ovarian cysts form part of the normal functioning of
the ovary and are always benign. They may be either "follicular cysts",
produced by all menstruating women every month and reaching up to 2-3cm
in diameter before they rupture at ovulation, or "corpus luteum cysts",
which appear after ovulation and may grow to produce "hemorrhagic cysts"
if ovulation does not occur or is delayed. Rupture of such a cyst can
sometimes cause painful ovulation or bleeding, which is often moderate
and resolves by itself. Organic ovarian cysts may be benign or malignant
and are not linked to the functioning of the ovary. They occur as either
"dermoid cysts", which are benign tumors that may nevertheless recur on
either ovary and contain elements derived from the skin (hairs, sebum,
teeth), or other organic cysts. |
