Ovarian cancer is often called a “silent killer” due to its subtle symptoms and the difficulty of early detection. This type of cancer can be challenging to diagnose in its early stages, as its symptoms can easily be mistaken for other less severe conditions. One of the most common imaging tests used in cancer detection is the CT scan, but can a CT scan detect ovarian cancer effectively? In this article, we will delve into the role of CT scans in diagnosing ovarian cancer and explore whether they are a reliable tool for early detection in Singapore.

What is a CT Scan?
A CT (computed tomography) scan is a medical imaging technique that combines multiple X-ray images to create cross-sectional views of the body. These images provide detailed pictures of the organs, bones, and soft tissues, helping doctors to detect abnormalities, growths, or masses that may suggest the presence of a disease such as cancer. While CT scans are commonly used to diagnose a variety of conditions, their role in detecting ovarian cancer is more complex.
Can a CT Scan Detect Ovarian Cancer?
A CT scan can be useful in detecting ovarian cancer, but it is not typically used as the primary method for diagnosis. In many cases, a CT scan may be ordered if a doctor suspects ovarian cancer based on symptoms or results from other tests. The scan may reveal a tumour or abnormal growth in the ovaries, but it cannot definitively confirm ovarian cancer. It can, however, provide valuable information about the size and spread of the cancer if it has already been diagnosed.
The Limitations of CT Scans for Ovarian Cancer
While CT scans are a powerful diagnostic tool, they are not always the most reliable for detecting ovarian cancer in its early stages. Ovarian tumours can be quite small or hidden within the pelvis, making them difficult to spot on a CT scan. Additionally, certain types of ovarian tumours, such as borderline or low-grade cancers, may not show up clearly on a CT scan.
Other imaging techniques, such as ultrasound or MRI, are often used in conjunction with CT scans to provide a more accurate diagnosis. These tests are better at detecting smaller tumours and can offer clearer images of the ovaries.
How Is Ovarian Cancer Diagnosed?
Ovarian cancer diagnosis typically begins with a pelvic exam and a review of the patient’s medical history. Blood tests, such as the CA-125 test, can help identify elevated levels of certain markers that may indicate ovarian cancer. If these tests suggest the possibility of cancer, imaging tests like ultrasound, CT scans, or MRI may be ordered to get a clearer picture.
In some cases, a biopsy or surgery may be required to obtain a tissue sample for further analysis and confirm the presence of cancer. A CT scan may be used to guide this process and help doctors plan the appropriate course of treatment.

The Importance of Early Detection
Early detection of ovarian cancer is key to improving survival rates. While a CT scan can be a valuable tool in assessing the spread of cancer, it is not the most effective method for early detection. Regular screenings and vigilance for symptoms are critical in identifying ovarian cancer at its earliest and most treatable stage.
