Ovarian Cysts — Are They Dangerous? Here's What Your Doctor Wants You to Know | Dr. Chetna Jain, Gurgaon

You went in for a routine ultrasound — maybe for period pain, maybe a check-up — and the report came back with three words that stopped you cold: ovarian cyst found. And suddenly your mind is racing. Is it cancer? Do I need surgery? Am I okay? Will this affect my ability to have children?

First — take a breath. I want to start by telling you something that will hopefully bring you immediate relief: the vast majority of ovarian cysts are completely harmless, resolve entirely on their own, and require no treatment whatsoever. Finding an ovarian cyst on an ultrasound is actually one of the most common findings in women of all ages — and in most cases, it is simply the ovary doing exactly what it is designed to do.

I am Dr. Chetna Jain, a gynaecologist in Gurgaon, and today I want to have an honest, straightforward conversation about ovarian cysts — what they actually are, the different types, which ones need attention, and which ones simply need a little patience and a follow-up scan.

So What Actually Is an Ovarian Cyst?

An ovarian cyst is a fluid-filled sac that develops on or inside an ovary. They range enormously in size — from tiny, pea-sized structures to large masses several centimetres across. They can occur in one ovary or both, and they can develop at any age — from adolescence through to post-menopause.

What is important to understand is that not all ovarian cysts are created equal. There are several different types — and the type, size, appearance on ultrasound, and the woman's age and symptoms together determine how we manage them. Let me walk you through the main ones.

The Different Types of Ovarian Cysts — And What They Mean

1. Functional Cysts — The Most Common and Almost Always Harmless

These are by far the most frequently found ovarian cysts, and they are a completely normal part of the menstrual cycle. Every month, your ovary develops a small follicle containing an egg. If ovulation does not happen quite as it should, this follicle can either continue growing (a follicular cyst) or, after ovulation, the empty follicle fills with fluid instead of dissolving (a corpus luteum cyst). Both are functional cysts — they arise from the normal function of the ovary, they are almost never cancerous, and the vast majority disappear completely on their own within one to three menstrual cycles. I see these every day in my clinic in Gurgaon and in the overwhelming majority of cases, my advice is simply: let us rescan in six to eight weeks.

2. Dermoid Cysts — Unusual but Usually Benign

Dermoid cysts are a type of benign tumour that can contain surprising things — hair, skin tissue, teeth, or fat — because they develop from embryonic cells. They sound alarming but are almost never cancerous. They do not resolve on their own and tend to grow slowly over time. Depending on their size and symptoms, surgical removal may eventually be recommended — but this is planned, non-urgent, and done laparoscopically in most cases.

3. Endometriomas — The Cyst That Deserves Extra Attention

An endometrioma — also called a chocolate cyst because of its dark brown fluid content — forms when endometrial tissue (the uterine lining) grows on the ovary. It is associated with endometriosis and is clinically significant because it can damage the surrounding ovarian tissue and reduce fertility over time. Endometriomas do not resolve on their own and typically require medical or surgical management. If you have been diagnosed with one, please do not delay a consultation.

4. Cystadenomas — Benign but Can Grow Large

These develop from the surface tissue of the ovary and can grow quite large — sometimes causing significant discomfort or a visible abdominal swelling. They are most commonly benign but their size and potential for torsion (twisting) means they are usually monitored carefully and removed surgically when they reach a significant size.

5. Polycystic Ovaries — Not the Same as Ovarian Cysts

I want to clear up a very common confusion here. When an ultrasound report mentions multiple small follicles in both ovaries — sometimes described as a polycystic appearance — this is different from a single ovarian cyst. Polycystic ovarian morphology is a feature of PCOS (Polycystic Ovary Syndrome) and is a hormonal condition, not a cystic disease. They are managed very differently. If your report mentions this, please come in for a proper evaluation rather than concluding you have ovarian cysts.

What Do Ovarian Cysts Feel Like? Recognising the Symptoms

Here is something that surprises many of my patients: most ovarian cysts cause no symptoms at all. They are discovered incidentally — on a scan done for an unrelated reason — and the woman had no idea they existed. This is completely normal and is another reason not to panic when one is found.

When symptoms do occur, they may include a dull ache or pressure in the lower abdomen on one side, bloating or a feeling of fullness, pain during or after sexual intercourse, irregular or painful periods, and a frequent need to urinate if the cyst is pressing on the bladder. These symptoms are worth mentioning to your doctor — but they are not automatically a sign of something serious.

However, there are symptoms that require urgent medical attention and should not be waited out:

• Sudden, severe, one-sided pelvic pain — this can indicate a ruptured cyst or ovarian torsion (twisting), both of which are medical emergencies

• Pain accompanied by fever and vomiting

• Feeling faint, dizzy, or experiencing rapid breathing alongside pelvic pain

If you experience any of these, please go to an emergency department immediately. Ovarian torsion in particular is a surgical emergency that requires prompt intervention to save the ovary.

The Question Everyone Is Really Asking: Could It Be Cancer?

I understand why this is the first place the mind goes — and I want to address it directly and honestly. The overwhelming majority of ovarian cysts in women of reproductive age are benign. Ovarian cancer is relatively rare, and cysts found in younger women are very unlikely to be malignant. The features that raise concern — and that I look for carefully on ultrasound and blood tests — include solid or mixed solid-and-fluid components within the cyst, irregular borders or internal septations, increased blood flow within the cyst on Doppler scan, rapidly increasing size, cysts occurring in post-menopausal women, and elevated tumour markers such as CA-125.

A simple, thin-walled, fluid-filled cyst in a woman of reproductive age — particularly if small — has an extremely low risk of malignancy. The evaluation of any ovarian cyst should always be done by an experienced gynaecologist who can interpret the full clinical picture, not by a radiology report alone. Please do not try to interpret your own ultrasound report. Come and let us look at it together.

How Are Ovarian Cysts Managed? It Is Usually Simpler Than You Think

Management depends entirely on the type, size, appearance, and symptoms of the cyst — and on the woman's age, medical history, and fertility plans. Here is a general guide to the approach I take:

• Watchful waiting: For most simple functional cysts under 5 to 6 cm in women of reproductive age, I recommend a repeat ultrasound in 6 to 8 weeks. The majority resolve completely on their own and no treatment is needed.

• Hormonal medication: In some cases, oral contraceptive pills are prescribed to suppress new cyst formation in women who experience recurrent functional cysts. They do not shrink existing cysts but can prevent new ones.

• Laparoscopic surgery: Recommended for cysts that are large, persistent, symptomatic, structurally complex, or that carry a risk of torsion. Laparoscopy is minimally invasive — performed through tiny incisions — with fast recovery, minimal scarring, and excellent outcomes. In most cases, the ovary itself is preserved.

• Urgent surgery: Required for ovarian torsion, ruptured cysts with significant bleeding, or any cyst with features highly suspicious of malignancy.

Will an Ovarian Cyst Affect My Fertility?

This is the question I hear most often from younger women — and the answer is, in most cases, reassuring. Simple functional cysts have no impact on fertility whatsoever. Endometriomas and large dermoid cysts can potentially reduce ovarian reserve if left untreated for a long time, or if surgical removal is not done carefully by an experienced laparoscopic surgeon. If you have an ovarian cyst and are trying to conceive or planning to in the future, please bring this up explicitly during your consultation so that fertility preservation is factored into the management plan.

My Message to You: Knowledge Is the Antidote to Fear

An ovarian cyst diagnosis can feel frightening — especially when it comes unexpectedly from a routine scan. But I hope this blog has helped replace some of that fear with clarity. Most cysts are benign. Most resolve on their own. Most women with ovarian cysts go on to live completely normal, healthy lives without any intervention at all.

What matters is getting the right evaluation from the right doctor — someone who will look at your full picture, explain what the finding means specifically for you, and create a management plan that is tailored to your age, symptoms, and goals. That is exactly what I do for every patient who comes to my clinic in Gurgaon, serving women from Palam Vihar, DLF, South City, Sector 22, Sector 23, and all of NCR.

If you have received an ultrasound report with an ovarian cyst finding — do not sit with the anxiety alone. Book an appointment. Let us look at it together, talk it through properly, and make sure you leave with answers, not more questions.

You deserve clarity. And you deserve care.
