Receiving an imaging scan result that mentions an ovarian mass or cyst can be unsettling. Concerns are natural to arise, especially with the thought of ovarian cancer. However, it is crucial to understand that in most cases, ovarian cysts are benign. While experienced radiologists can identify characteristics differentiating a benign cyst from a suspicious mass, a team of expert oncologists can ensure accurate diagnosis and peace of mind. This blog helps you with the clarity in understanding the distinction between common ovarian cysts and the less frequent, but serious, ovarian cancer through scan images.
Synopsis
Understanding ovarian cysts: Often harmless
Ovarian cysts are fluid-filled sacs within or on the surface of an ovary. This is common in women of reproductive age. Most are functional cysts that form as a normal part of the menstrual cycle and are usually harmless. Types of ovarian cysts include functional cysts like follicular, corpus luteum, benign cysts like dermoid, cystadenomas, and endometriomas. Case studies reveal that over 95% of ovarian cysts are benign and often resolve on their own within a few weeks or months.

Ovarian cancer: What sets it apart
While ovarian cancers are less common compared to benign cysts, their characteristics call for awareness. Early detection is vital for better outcomes, and understanding the subtle difference between an ovarian cyst and ovarian cancer is imperative for informed decision making, prompt and appropriate medical intervention and peace of mind.
Recognising potential symptoms
Ovarian cancer often presents with vague symptoms or persistent changes, such as:
-
Abdominal bloating
-
Pelvic pain
-
Feeling full quickly
-
Changes in bowel habits
-
Fatigue
-
Unexplained weight loss.
Ovarian cysts, on the other hand, show up with:
-
Pelvic pain or discomfort
-
Bloating or abdominal swelling
-
Irregular periods
-
Pain during intercourse
-
Frequent urination
-
Sudden severe pain if the cyst ruptures or twists
If symptoms persist for weeks, consult a healthcare professional. Early diagnosis, when localised, has a survival rate exceeding 90%, highlighting the importance of timely medical attention.
The diagnostic journey
A comprehensive evaluation is essential for a proper understanding of ovarian cyst vs ovarian cancer, difference that can impact your state of mind as well as the treatment approach. This calls for the use of advanced diagnostic tools as well as the expertise of specialists. Key diagnostic tools and methods involve:
-
Detailed medical history and physical exam- Assessment of symptoms, menstrual history, family history, and physical examination.
-
Transvaginal Ultrasound (TVUS)- Imaging test using sound waves to image the ovaries. Transvaginal ultrasound ovarian findings help assess shape, size, internal structure, and blood flow.
-
MRI or CT scan- For more detailed images, if the ultrasound is inconclusive or raises concerns.
-
Blood tests- These can support the early screening and evaluation of ovarian cancer, especially in women at higher risk. These include:
-
CA-125 test- The CA-125 blood test for ovarian cancer measures cancer antigen 125. While elevated levels can be associated with ovarian cancer, it is not definitive, as benign conditions like endometriosis or fibroids can also elevate it. It is useful, especially in postmenopausal women, when combined with imaging.
-
Risk of Malignancy Index (RMI)- This combines ultrasound findings, CA-125, and menopausal status to calculate malignancy probability.
-
Biopsy or surgical intervention- The definitive way for diagnosis is often surgical removal of the mass for pathological examination.
What do the scan results actually mean?
Understanding scan terminology is vital to mark the difference between ovarian cyst and ovarian cancer. A ‘simple cyst’ is typically a fluid-filled sac with smooth walls and no internal solid components. It is almost always benign and often requires watchful waiting. A ‘complex cyst’ or ‘solid mass' indicates irregularities (solid components, thick walls, internal septations or compartmental separations) and warrants closer evaluation, as these have a higher likelihood of malignancy. ‘Vascularity’ (blood-flow within the mass) and ‘ascites’ (fluid in the abdomen) can also be suspicious findings.

FAQ's
Most ovarian cysts are benign and do not become cancerous. However, certain complex or persistent cysts, especially after menopause, may require detailed evaluation to rule out the possibility of ovarian cancer or precancerous changes.
Ovarian cyst treatment may include observation, medications, or surgery, depending on the cyst type and symptoms, while ovarian cancer treatment often involves surgery, chemotherapy, targeted therapy, and ongoing specialist care for better outcomes.
Yes, ovarian cancer can develop silently in its early stages. Symptoms are often mild or mistaken for digestive or menstrual issues, which is why regular health check-ups and timely medical evaluation are important.
Some ovarian cysts, especially those related to conditions like endometriosis or polycystic ovary syndrome, may affect fertility. Early diagnosis and appropriate treatment can help protect reproductive health and future pregnancy outcomes.
Some cases of ovarian cancer are linked to inherited genetic mutations such as BRCA1 and BRCA2. Women with a strong family history of ovarian, breast, or related cancers may benefit from genetic counselling and regular screening.
