What Size of Ovarian Cyst is Dangerous?

Ovarian cysts are common among women of all ages, typically forming as part of the natural menstrual cycle. But there are some instances when women wonder: ‘What size of ovarian cyst is dangerous?’  

Understanding the potential risks associated with the size of ovarian cyst is crucial, as most cysts are harmless and resolve on their own. However, larger cysts can sometimes pose health risks. 

In this blog, you will discover what size of ovarian cyst is dangerous and about it. 

What are ovarian cysts?

Ovarian cysts are sacs filled with fluid that form within or on your ovaries, which are an integral part of the female reproductive system.  

These cysts can vary in size, from tiny to quite large, and can appear in one or both ovaries.  

These cysts are common among women and can develop at any age, spanning from the onset of menstruation to menopausal years. 

What are the different types of cyst in ovary?

Some common types of ovarian cysts include: 

  • Functional Cysts are the most common type of ovarian cysts and are usually harmless. They are formed when your menstrual cycle follows its regular pattern. 
  • Follicular Cysts develop when a follicle, a small sac within the ovary containing an egg, does not release the egg during the menstrual cycle, resulting in the formation of a cyst. 
  • Dermoid Cysts contain various types of tissue, including hair, skin, and sometimes teeth, and are usually benign.  
  • Endometriomas develop in women with endometriosis, a condition where the uterine tissue lining grows outside the uterus, such as ovaries. 
  • Corpus Luteum Cysts form follicle sac, which releases the egg and does not dissolve after ovulation. It may fill with fluid, resulting in cyst formation. 
  • Cystadenomas are growths on the surface of the ovary and are usually filled either with a watery or mucous-like material.

What is the significance of the size of an ovarian cyst?

The ovarian cyst size is crucial in determining potential risks and associated complications. 

While the size alone does not determine whether a cyst is benign or malignant, it can provide information about the potential danger larger cysts pose to a woman’s health and the need for further evaluation or treatment.  

What are the symptoms of ovarian cysts?

Ovarian cysts, although common, can often go unnoticed as they may not cause any symptoms. However, in some cases, women may experience certain signs that could indicate the presence of an ovarian cyst. 

  • Pelvic pain or pressure 
  • Pain on one side of the lower abdomen, either dull or sharp 
  • A feeling of fullness or bloating 
  • Irregular and painful periods 
  • Pain during intercourse 
  • Changes in menstrual cycle 
  • Weight gain 
  • Feeling to urinate frequently 

What is the normal size of ovarian cyst in mm?

A normal size ovarian cyst in mm is 3 cm (30 mm) in diameter.  

Such cysts are generally considered normal and benign, often resolving on their own without medical intervention. Regular pelvic exams can help detect these small, non-threatening cysts. 

What size ovarian cyst is considered large?

An ovarian cyst is typically considered large if it measures more than 6 cm (60 mm) in diameter. 

Large ovarian cysts may require closer monitoring and, in some cases, medical intervention. When considering what size of ovarian cyst is dangerous, It’s essential for women experiencing symptoms or concerns related to ovarian cysts of any size to consult with a gynecologist for proper evaluation and management. 

What size of ovarian cyst is dangerous in mm?

Ovarian cysts can range from very small (a few millimeters) to large (over 10 cm or more).  

Some cysts, such as functional cysts, can resolve on their own. Other types of cysts, such as cystadenomas or dermoid cysts, can also reach larger sizes and pose a higher risk. 

When considering what size of ovarian cyst is dangerous in mm or size of ovarian cyst is dangerous in cm, it is believed that ovarian cysts larger than 6 cm (60 mm) are dangerous for health and need medical intervention.

What are the risks and complications of large ovarian cysts?

Complications associated with larger ovarian cysts can include: 

  • Torsion or twisting 
  • Rupture of the cyst, causing serious abdominal pain and bleeding 
  • Infected ovarian cyst 
  • Ovarian cancer (rarely) 

How are ovarian cysts diagnosed and size determined?

Our gynecologists use various diagnostic procedures to assess the ovarian cyst size. 

  • The primary method is ultrasound imaging, which delivers non-invasive, detailed insights into the cyst’s size, shape, and location.  
  • Pelvic examinations and laparoscopy also offer initial insights about the existence of ovarian cysts. 
  • In certain cases, additional tests like CT or MRI scans may be necessary to obtain a more detailed evaluation of the size and characteristics of cysts. 
  • If you have a partially solid cyst in ovary, a blood test may be advised to test protein levels called CA 125. It’s often higher in people who have ovarian cancer or have conditions like uterine fibroids, endometriosis, and pelvic inflammatory disease. 

How is ovarian cyst treated?

If you have an ovarian cyst, a gynecologist will recommend a treatment depending on the size, type, and symptoms associated with the cyst. 

Here are some of the most common ovarian cyst treatment options: 

Wait-and-See Approach:  

You may be recommended a “watch and wait” approach to monitor your cyst through regular check-ups and imaging tests to see if it resolves on its own without intervention. 

Medication:  

If you often develop functional cysts, you may be prescribed hormonal contraceptives like birth pills. This medication can help regulate hormones and prevent new cyst formation, especially for larger cysts causing discomfort. 

If you have any pain and discomfort from an ovarian cyst, you may recommend over-the-counter (OTC) pain relievers to help relieve pain. 

Surgical Options:  

Sometimes, an ovarian cyst treatment may require surgical intervention. This may be necessary when a cyst is large, doesn’t go away, or causes serious symptoms. Additionally, you could also need surgery if you’re near or past menopause, as your cysts carry a higher risk of being cancerous. 

The doctor may advice undergoing the following surgical procedures: 

  • Cystectomy: Surgically removing the cyst while preserving the affected ovary. 
  • Oophorectomy: Removal of one or both ovaries, along with the cyst, especially if the cyst is complex, recurrent, or cancerous. 
  • Laparoscopic Surgery: Minimally invasive surgery conducted through small incisions using a laparoscope, which allows for quicker recovery compared to traditional open surgery.
