Endometriosis — Hidden in plain sight
This student blog post is written by Vedanshi S. and is about a medical condition called endometriosis. Do you want to learn more about this condition that impacts a large number of people but often goes untreated and undiagnosed? Take it away, Vedanshi!
I was first introduced to Endometriosis back in grade 11. My mom woke in the early hours of the morning with excruciating pain in her abdominal area, and rushed to the QEII. They ran through a series of tests and the pain eventually subsided on its own. They found nothing wrong except some of her ovaries being scrunched up/unclear in the tests. We were sent home with the notion that it might have been a kidney stone that passed away and an appointment with the gynae for the weird ovaries which wasn’t for another couple months. We spent the entire month coming in and out of the Emergency for about eight times for this recurring pain. The gynae appointment was shifted up and Endometriosis was finally diagnosed. My mom was scheduled for a surgery the next week and successfully recovered. This gap in medical knowledge and lack of urgency left me with a deep sense of injustice and resentment. I thought that I would finally leave this chapter behind but a few weeks ago, I found a reel on Instagram that talked about a research paper on how Endometriosis affects male partners(?!). Money is being put towards such foolish research instead of some kind of technology for diagnosing the said diseases. It was then that I decided to write my blog post on Endometriosis and educate the future science leaders of tomorrow about this disease that affects many women around the world.
Endometriosis is defined by tissue similar to the uterine lining growing outside the uterus, where it should not be. These cells can implant on the ovaries, uterus-supporting ligaments, bowel, bladder, and other pelvic structures, where they respond to hormones each month and trigger inflammation, scarring, and pain, see figure 1 (Mehedintu et al., 2014). Despite affecting approximately 10%-15% of women of reproductive age, diagnosis is often delayed by several years due to the variability of symptoms and lack of definitive, non-invasive diagnostic methods (Mehedintu et al., 2014). This makes endometriosis feel especially invisible to patients, because their suffering is real even when the disease is not easy to see on routine tests.
Endometriosis is intriguing from the standpoint of cell biology since it includes cells surviving in unexpected places. The leading ideas about how this happens include retrograde menstruation, where menstrual tissue flows backward into the pelvic cavity, as well as immune dysfunction, metaplasia, and genetic or epigenetic influences that allow ectopic cells to attach, persist, and grow (Rolla, 2019; Mehedintu et al., 2014). Another important factor is the immune system. Normally, the body should recognize and remove misplaced tissue. In endometriosis, this process does not function properly. Immune cells may fail to clear abnormal tissue, allowing it to implant and grow in areas where it does not belong (Mehedintu et al., 2014). In other words, the disease is not just about where the tissue is located; it is about how cells communicate, how they respond to estrogen, and how they evade normal clearance by the immune system.
The more recent findings further demonstrate why endometriosis should be discussed in relation to cell biology. Its characteristics include hormone-dependent growth, aberrant adhesion, altered cytokine signalling, and persistent inflammation, indicating that cell signalling networks, rather than only anatomy, create the disease (Rolla, 2019; Mehedintu et al., 2014). Researchers now think of it as a complex, multigenic disorder rather than a simple mechanical problem (Rolla, 2019). That shift matters because it explains why a condition that seems straightforward from the outside can be so biologically layered underneath.
One of the most frustrating parts of endometriosis is the delay in diagnosis. A blood test still does not reliably diagnose it, and imaging can miss disease, especially deeper lesions, so laparoscopy remains the gold standard for confirmation, see figure 2 (Rolla, 2019; Mehedintu et al., 2014). Even then, many patients spend years bouncing between clinics before someone connects the symptoms to endometriosis (Mehedintu et al., 2014). That delay is not just inconvenient; it can mean more pain, more inflammation, and more damage over time.

There is still no cure, but treatment is aimed at reducing pain, slowing lesion growth, and improving quality of life. Hormonal therapies such as combined oral contraceptives, progestogens, and GnRH-based treatments work by lowering estrogen-driven stimulation of the lesions, because endometriosis is strongly hormone dependent (Rolla, 2019; Mehedintu et al., 2014). Surgery can remove visible lesions and help with pain or fertility, but recurrence is common and results vary depending on how deep or extensive the disease is (Mehedintu et al., 2014).
What stands out to me is that treatment is not only about removing tissue; it is about managing a chronic disease that affects daily life, fertility, mental health, and trust in healthcare. It is evident that improved biomarkers, improved imaging, and a deeper comprehension of the molecular basis of the disease are all necessary (Rolla, 2019; Mehedintu et al., 2014). Endometriosis reminds us that when cells behave abnormally, the effects can reach far beyond the body’s tissues and into a person’s education, work, relationships, and sense of being believed.
Learning about the science behind endometriosis made me realize that my mom’s experience wasn’t just a personal struggle — it was part of a larger pattern. The lack of research, combined with the complexity of the disease, creates a situation where patients are left without clear answers or timely care. While research is improving, there is still a long way to go. No one should have to wait extended periods of time to have their pain recognized, and increasing awareness and scientific understanding is essential to making that change.
