Health Check; Ovarian Cysts
What Are Ovarian Cysts?
Highlights
Most women will experience a cyst on the ovaries at least once, and most are painless, cause no symptoms, and are discovered during a routine pelvic exam.
Symptoms of an ovarian cyst include nausea, vomiting, bloating, painful bowel movements, and pain during sex.
In rare cases, an ovarian cyst can cause serious problems, so it’s best to have it checked by your doctor.
The ovaries are part of the female reproductive system. They’re located in the lower abdomen on both sides of the uterus. Women have two ovaries that produce eggs, as well as the hormones estrogen and progesterone.
Sometimes, a fluid-filled sac called a cyst will develop on one of the ovaries. Many women will develop at least one cyst during their lifetime. In most cases, cysts are painless and cause no symptoms.
Types of Ovarian Cysts
There are various types of ovarian cysts, such as dermoid cysts and endometrioma cysts. However, functional cysts are the most common type. The two types of functional cysts include follicle and corpus luteum cysts.
Follicle Cyst
During a woman’s menstrual cycle, an egg grows in a sac called a follicle. This sac is located inside the ovaries. In most cases, this follicle or sac breaks open and releases an egg. But if the follicle doesn’t break open, the fluid inside the follicle can form a cyst on the ovary.
Corpus Luteum Cysts
Follicle sacs typically dissolve after releasing an egg. But if the sac doesn’t dissolve and the opening of the follicle seals, additional fluid can develop inside the sac and this accumulation of fluid causes a corpus luteum cyst.
Other types of ovarian cysts include:
Dermoid cysts: sac-like growths on the ovaries that can contain hair, fat, and other tissue.
Cystadenomas: non-cancerous growths that can develop on the outer surface of the ovaries.
Endometriomas: tissues that normally grow inside the uterus can develop outside the uterus and attach to the ovaries, resulting in a cyst.
Some women develop a condition called polycystic ovary syndrome. This condition means the ovaries contain a large number of small cysts. It can cause the ovaries to enlarge, and if left untreated, polycystic ovaries can cause infertility.
Symptoms
Often times, ovarian cysts do not cause any symptoms. However, symptoms can appear as the cyst grows. Symptoms may include:
- abdominal bloating or swelling
- painful bowel movements
- pelvic pain before or during the menstrual cycle
- painful intercourse
- pain in the lower back or thighs
- breast tenderness
- nausea and vomiting
Severe symptoms of an ovarian cyst that require immediate medical attention include:
- severe or sharp pelvic pain
- fever
- faintness or dizziness
- rapid breathing
These symptoms can indicate a ruptured cyst or an ovarian torsion. Both complications can have serious consequences if not treated early.
Complications
Most ovarian cysts are benign and naturally go away on their own without treatment. These cysts cause little, if any, symptoms. But in a rare case, your doctor may detect a cancerous cystic ovarian mass during a routine examination.
Ovarian torsion is another rare complication of ovarian cysts. This is when a large cyst causes an ovary to twist or move from its original position. Blood supply to the ovary is cut off, and if not treated, it can cause damage or death to the ovarian tissue. Although uncommon, ovarian torsion accounts for nearly 3 percent of emergency gynecologic surgeries.
Ruptured cysts, which are also rare, can cause intense pain and internal bleeding. This complication increases risk of an infection and can be life-threatening if left untreated.
Diagnosis
Your doctor can detect an ovarian cyst during a routine pelvic examination. They may notice swelling on one of your ovaries and order an ultrasound test to confirm the presence of a cyst. An ultrasound test (ultrasonography) is an imaging test that uses high-frequency sound waves to produce an image of your internal organs. Ultrasound tests help determine the size, location, shape, and composition (solid or fluid filled) of a cyst.
Imaging tools used to diagnose ovarian cysts include:
CT scan: a body imaging device used to create cross-sectional images of internal organs.
MRI: a test that uses magnetic fields to produce in-depth images of internal organs.
Ultrasound device: an imaging device used to visualize the ovary.
Because the majority of cysts disappear after a few weeks or months, a doctor may not immediately recommend a treatment plan. Instead, they may repeat the ultrasound test in a few weeks or months to check patient's condition. If there aren’t any changes in condition or if the cyst increases in size, the doctor will request additional tests to determine other causes of the symptoms.
These include:
- pregnancy test: to make sure patient is not pregnant.
- hormone level test: to check for hormone-related issues, such as too much estrogen or progesterone.
- CA-125 blood test: to screen for ovarian cancer
Treatment
The doctor may recommend treatment to shrink or remove the cyst if it doesn’t go away on its own or if it grows larger.
Birth Control Pills
If one has recurrent ovarian cysts, the doctor may prescribe oral contraceptives to stop ovulation and prevent the development of new cysts. Oral contraceptives can also reduce the risk of ovarian cancer. The risk of ovarian cancer is higher in postmenopausal women.
Laparoscopy
If the cyst is small and results from an imaging test rule out cancer, the doctor can perform a laparoscopy to surgically remove the cyst. The procedure involves the doctor making a tiny incision near the navel and then inserting a small instrument into the abdomen to remove the cyst.
Laparotomy
If one has a large cyst, the doctor can surgically remove the cyst through a large incision in the abdomen. They’ll conduct an immediate biopsy, and if they determine that the cyst is cancerous, they may perform a hysterectomy to remove the ovaries and uterus.
Prevention
Ovarian cysts can’t be prevented. However, routine gynecologic examinations can detect ovarian cysts early. Benign ovarian cysts don’t become cancerous. However, symptoms of ovarian cancer can mimic symptoms of an ovarian cyst. Thus, it’s important to visit your doctor and receive a correct diagnosis. Alert your doctor to symptoms that may indicate a problem, such as:
- changes in your menstrual cycle
- ongoing pelvic pain
- loss of appetite
- unexplained weight loss
- abdominal fullness
Outlook
The outlook for premenopausal women with ovarian cysts is good. Most cysts disappear within a few months. However, recurrent ovarian cysts can occur in premenopausal women and women with hormone imbalances.
If left untreated, some cysts can decrease fertility. This is common with endometriomas and polycystic ovary syndrome. To improve fertility, the doctor can remove or shrink the cyst. Functional cysts, cystadenomas, and dermoid cysts do not affect fertility.
Although some doctors take a “wait and see” approach with ovarian cysts, your doctor may recommend surgery to remove and examine any cyst or growth that develops on the ovaries after menopause. This is because the risk of developing a cancerous cyst or ovarian cancer increases after menopause. However, ovarian cysts don’t increase the risk of ovarian cancer. Some doctors will remove a cyst if it’s larger than 5 centimeters in diameter.
