I am actually wondering if all your symptoms are actually related to endometriosis (one type of complex cyst is an endometrioma which is related to endo).
CA125 can be elevated if endometriosis is present as well so would not assume the worst by any means. I would see if you can get definite confirmation that you will be given these results next week, in this case they are wise to not actually give you the results because they are not qualified to interpret them at all properly. I would also in the meantime keep a daily pain and symptom diary of your symptoms if you have not already been doing this.
An ovarian cyst can also contain both fluid and solid material, and this is known as complex ovarian cyst. Complex ovarian cysts occur less frequently and are not related to the normal menstrual cycle. These are generally harmless (benign). There are three types of complex ovarian cysts: dermoid cysts, cystadenomas, and endometriomas.
Dermoid cysts -Theseare the most common type and develop during the childbearing age. The cysts contain structures such as the teeth, hair, nail, bone, or sweat glands. It is a slow growing and rarely cancerous. It causes significant pain when the cyst twists.
Cystadenomas - Cystadenomas are benign cysts that develop from cells that cover the outer layer of the ovary. There are two types, mucinous and serous cystadenoma. Mucinous adenoma contains a sticky, thick fluid. It can grow up to 30 cm (12 in) in diameter and weigh up to 100 pounds. It can fill up the abdomen and cause pressure on other structures such as the bladder and bowel. It can also block the blood supply in the ovaries and cause twisting or torsion of the ovaries. Serous cystadenoma contains a thin, watery fluid. It does not grow as big as mucinous cystadenoma but can cause symptoms when it ruptures.
Endometriomas - Endometriomas are blood-filled cysts that arise from endometriosis. Endometriosis is a condition wherein the cells that are normally found inside the uterus grow outside the uterus, such as the ovaries, fallopian tubes, bladder, or bowel. Endometriomas can also be called chocolate cysts. This is because the cells that grow in the ovaries bleed and become brown over time and result in a brown-colored cyst.
Patients with ovarian cysts are often concerned about malignancy. Complex ovarian cysts are generally benign. The risk of malignancy is generally higher among postmenopausal women, occurring in 0.3% of cases. It has been reported that a malignant change occurs in small percentage of women with dermoid cyst and endometrioma. Cystadenoma has not been reported to become malignant.
