Historically invasive and delayed, endometriosis diagnosis is entering a new era. Advancements in non-invasive detection, including imaging innovations, transvaginal ultrasounds and salivary tests, signal a turning point for women’s health.
Endometriosis is one of the most common yet underdiagnosed gynaecological diseases. It affects approximately 190 million women around the world and remains incompletely understood by the medical community.
The condition can cause severe pain, infertility, and heavy periods, occurring when cells similar to those lining the uterus grow elsewhere in the body. With diagnostic delays of 5 to 12 years, endometriosis diagnosis has often required waiting for surgery to confirm the disease.
However, the invasiveness, cost, and delay throughout the endometriosis diagnosis pathway have spurred new approaches that are going beyond surgery. Non-surgical detection methods, such as advanced imaging and new blood tests, are considered breakthroughs that offer hope for earlier endometriosis detection, solid multidisciplinary coordination, and a better experience for women’s health across gynaecology.

Understanding Endometriosis in Women's Health
Endometriosis is a chronic, complex and multidisciplinary condition in women’s health that involves inflammation, hormones, and the immune system. Affecting nearly 1 in 10 people of reproductive age worldwide, it occurs when endometrial-like tissue grows outside the uterus, often around pelvic organs.
This tissue, which resembles the uterine lining, responds to female hormone changes during the menstrual cycle. Since the tissue has no way of leaving the body, unlike a typical uterine layer that sheds and causes a period, it can cause adhesions, nodules, and lesions around pelvic and abdominal organs, triggering an inflammatory response.
The cause for endometriosis in women’s health is still a mystery to science. The condition was originally thought to be caused by retrograde menstruation, however, it does not apply to every endometriosis diagnosis.
Some studies show that endometriosis is more common in people with heavy periods, early menarche, and late menopause. Other research investigated genetic, inflammatory, and hormonal alterations as potential causes or contributors. Further research suggests the development of endometriosis may be influenced by excess oestrogen in the body.
Identifying and Managing Symptoms for Endometriosis Diagnosis
Endometriosis symptoms can vary among patients. While some of them may be asymptomatic, others can experience a range of physical and mental effects, making endometriosis diagnosis challenging for medical doctors.
Physical symptoms, for instance, can begin in early adolescence or later in adulthood. Beginning at an early age can lead a person to normalise high levels of pain, assuming it’s normal to have a painful menstrual cycle, when it may be caused by endometriosis or another medical condition. According to a systematic review, the prevalence of endometriosis is about 42% among women with chronic pelvic pain.
Besides pelvic pain, common endometriosis symptoms include:
- Moderate to severe premenstrual/menstrual cramps
- Painful bowel movements
- Pain in the lower back, abdomen or thighs, during the menstrual cycle
- Dyspareunia
- Dysmenorrhoea
- Heavy periods
- Rectal pain and rectal bleeding
- Infertility
Endometriosis can also induce mental and social symptoms in women’s health. Scientists now understand that endometriosis is a whole-body inflammatory condition that can affect a person’s nervous system and have a significant impact on their quality of life, reducing their ability to work, maintain relationships, and participate in social activities. Women with the condition have also been reported off as too anxious about their health or even as attention-seekers.
As there’s still no cure for it, the disease is treated by managing symptoms. Endometriosis treatment may be hormonal, non-hormonal, or surgical, depending on the patient. Options include combined or progestin-only contraceptives, NSAIDs, hormonal suppression therapy, and alternatives such as acupuncture after the diagnosis.
Advancements in Women's Health for Endometriosis Diagnosis
Historically, the gold standard for endometriosis diagnosis was to remove tissue from a patient via surgery and examine it under a microscope. Although surgical procedures such as laparoscopy are still recommended – currently more as a treatment for extreme cases than as a diagnostic tool itself – scientific advances in women’s health are transforming the diagnostic landscape. Some of them are:
Transvaginal Ultrasound (TVUS) and Magnetic Resonance Imaging (MRI)
Non-invasive imaging, such as transvaginal ultrasound (TVUS) and MRI, are now critical to endometriosis diagnosis. These help patients access treatments sooner for persistent pain or infertility, avoiding surgery wait times.
Although both types of imaging tests are the most recommended, transvaginal ultrasounds better detect deep infiltrating endometriosis, especially in patients with surgical history and internal scarring. Patients with pelvic muscular disorders or vaginismus might not be candidates for a procedure like TVUS. In this case, a pelvic MRI would be a more effective and comfortable option for endometriosis detection.
Emerging Blood Test for Endometriosis Detection.
Beyond imaging, blood-based tests are revolutionising women’s health diagnostics. A recent trial, in collaboration with the Royal Women’s Hospital and the University of Melbourne, reported that a blood-based protein biomarker test achieved 99.7% accuracy in distinguishing severe cases of endometriosis from those of patients without the condition, yet presenting with similar symptoms. Even in the early stages of the disease, when blood markers may be more difficult to detect, the test’s accuracy remained over 85%.
Such advances present a strategic opportunity for clinicians to integrate protein biomarkers into practice in women’s health, particularly where the access to imaging is limited, too expensive, or when early intervention is critical.
Bacterium Detection
Researchers in Japan have found that Fusobacterium, a bacterium often associated with oral and gut health, appears more frequently in women with endometriosis (approximately 64%) than in those without (less than 10%).
Laboratory tests revealed that this infection activates TGF-β (transforming growth factor beta) signalling, converting fibroblasts into myofibroblasts that facilitate lesion growth and spread. In mouse models, introducing Fusobacterium resulted in larger, more numerous lesions, whereas antibiotic treatment prevented or reduced them. The study suggests that the Fusobacterium infection may facilitate the development of endometriosis and that antibiotics could become part of future treatment strategies.
Salivary Test
Another study investigated whether a simple saliva sample could be used as an endometriosis diagnosis. By examining small molecules called microRNAs, researchers identified a pattern that accurately predicted almost all cases of the disease in women. Many of these microRNAs are linked to processes involved in endometriosis.
Since saliva is easy to collect, this test could one day offer a quick, non-invasive way to help diagnose the condition, although it still requires further validation.
A Multidisciplinary Approach to Women's Health
For a successful endometriosis diagnosis, a collaborative approach in women’s health is needed. For physicians across specialties, including general practice, gastroenterology, paediatrics, pain medicine, and beyond, the developments cited above underscore the importance of awareness and readiness for an effective non-invasive detection.
By recognising both gynaecological and systemic manifestations, and by leveraging emerging tools, clinicians can reduce diagnostic delays and improve access to timely care. Early and accurate endometriosis diagnosis not only alleviates suffering but also enhances quality of life for millions of women worldwide.
