Can Endometriosis Cause Cancer? Understanding the Risks and Links
Can endometriosis cause cancer? I get asked this a lot! Indeed, it's a crucial question for many who suffer from this chronic condition that behaves a lot like cancer in many ways (as I describe in detail in my best-selling book Heal Endo) but is not cancer. And many of us are worried: will my endo turn into cancer? In short, the answer is very rarely! Very rarely does endometriosis itself turn into cancer. So that’s good to know.
However, for some of us, there does appear to be a link between having endometriosis and developing cancer. So instead of A turning into B (endo turning into cancer), it’s more like you have A and then get B, too. And for those at higher risk, it's really important to know.
Truthfully, endometriosis can indeed increase the risk of certain types of cancer, particularly ovarian cancer and endometrial cancer, colon cancer, and others. This article delves into the details of these risks, the types of cancer linked to endometriosis, and the mechanisms behind these connections.
Key Takeaways
Endometriosis is linked to an increased risk of cancers, particularly ovarian and endometrial cancers. This doesn't mean you will get cancer with endo, but rather, there is an increased risk. This is why we should all be proactive about health monitoring.
This is rarely due to lesions themselves! Remember, endometriosis is a systemic disease (more than just lesions), and the chronic inflammation, immune dysregulation, oxidative stress, and hormonal imbalances that often accompany endometriosis can also create an environment conducive to cancer development, highlighting the importance of understanding these mechanisms.
There seems to be a stronger association between developing cancer and endo if you have worse endo (deeper, more widespread, and ovarian endometriomas). So, those with more advanced endometriosis and ovarian endometriomas should be even more on top of regular screening.
Regular screenings, a healthy lifestyle (per Heal Endo), and open discussions with healthcare providers can significantly improve early detection and management of potential cancer risks in women with endometriosis. Don’t stress! Just be aware, ya’ll.
Types of Cancer Associated with Endometriosis
Endometriosis is a disease of chronic inflammation, immune dysfunction, nervous system impairment, microbiome imbalances, oxidative stress, and more. Because of this "whole-body-on-fire" grouping of imbalances, it's perhaps not surprising to know it may also be connected (for some of us) to a heightened likelihood of various cancers. Ovarian cancer, endometrial cancer, and breast cancer are the principal cancers linked with endometriosis. There's also some evidence that there is a very large association between adenomyosis and colon cancer.
Although the association with breast cancer and thyroid cancer may be less pronounced, recognizing all possible risk factors remains critical—including those pertaining to other forms of cancer. Each type poses distinct challenges and hazards that we will delve into comprehensively in subsequent sections.
Understanding these links is vital for women suffering from endometriosis so we can take early measures to oversee our wellness! Me included.
Ovarian Cancer Risk
Women with severe endometriosis, particularly those with deep infiltrating endometriosis and ovarian endometriomas, face a significantly increased risk of developing ovarian cancer. In fact, women with more severe forms of endometriosis have a more than fourfold higher risk of developing ovarian cancer compared to those without the condition. Specific subtypes of ovarian cancer, such as clear cell and endometrioid cancers, are notably associated with severe forms of endometriosis (rather than everyone who has endo, which is a lot of women).
Endometrial Cancer Risk
Women with endometriosis face a considerably elevated risk of developing endometrial cancer. This could be due to many factors, including hormonal imbalances, chronic inflammation, chemicals that alter the endometrial lining behavior, bacterial infections of the reproductive tract, and genetic alterations. Research indicates that those with endo have a 7.5-fold greater likelihood of being diagnosed with type I endometrial cancer compared to those without endometriosis. In cases where the severity of the condition is more extreme, this risk can skyrocket by nearly 19 times, suggesting a direct correlation between an increase in risk and the intensity of the disease.
Having a family history significantly raises one’s susceptibility to this form of cancer. It approximately doubles their chances as opposed to those without such hereditary links. Recognizing these heightened risks empowers women afflicted by endometriosis to engage in proactive measures aimed at preventing and ensuring early detection for better management outcomes against cancers like type I Endometrial Cancer.
Modest Cancer Risks: Breast, thryoid, non-Hodgkin lymphoma. and melanoma
Research has demonstrated that there is a modest link between endometriosis and breast cancer. The risk of developing breast cancer for women with endometriosis increases by a factor of 1.082, which, although slight, warrants attention. Women who have been diagnosed with endometriosis should be informed about this potential hazard and engage in discussions regarding it with their medical professionals.
Women with endometriosis may face increased risks for other types of cancer, although these associations are less well-documented. Emerging research suggests a potential link between endometriosis and thyroid cancer. The hormonal imbalances and chronic inflammation characteristic of endometriosis could contribute to a slightly elevated risk of developing thyroid cancer.
Additionally, some studies have hinted at a possible connection to non-Hodgkin lymphoma and melanoma, though more research is needed to confirm these associations.
Adenomyosis and Its Link to Colon Cancer
Recent research has shed light on the potential connection between adenomyosis and an increased risk of colorectal cancer, particularly when adenomyosis coexists with non-ovarian endometriosis. While ovarian endometriosis is well-documented to increase the risk of ovarian cancer significantly, adenomyosis presents a unique profile of risks.
The study found that adenomyosis is associated with a fivefold increase in the risk of both ovarian and endometrial cancers. However, a surprising finding was that those with both adeno and endo had a 13x increase in risk of developing colorectal cancer... a pretty significant association.
Given these findings, it is crucial for women with adenomyosis, particularly those with additional endometriosis, to engage in regular cancer screenings and discussions with their healthcare providers. Early detection and proactive health management can significantly improve outcomes and provide reassurance for those at higher risk of CRC (especially if it runs in your family line!).
Mechanisms Linking Endometriosis and Cancer: Why does this happen?
Image from my book, reminding us that there are many factors within our control to help bring a body ecology that’s out of balance back into homeostasis.
Several biological processes underpin the association between endometriosis and cancer. While there is the rare case endometriosis actually turns into cancer, it's much more often we see someone with endometriosis go on to develop cancer separately. This is important to distinguiish for mental health: it's rare for endo to actually turn into cancer.
Instead, we see the body ecology that supports endometriosis (the one I desribe at length in my book) is the same body ecology that supports the cancer process: persistent inflammation, immune dysfunction, microbiome imbalances, and more. All of this fosters not only active endo, but also a setting where cancer may thrive. This inflammatory state can lead to oxidative stress, which in turn causes damage to DNA—a key element in both initiating cancer and driving its progression.
Hormonal imbalances involving heightened levels of estrogen are common to both endometriosis and various cancers. Such imbalances have the potential to fuel tumor growth and amplify the general risk of developing cancer. Understanding these mechanisms is critical for crafting specialized treatments and prevention plans aimed at women living with endometriosis.
Genetic Factors and Family History: Determining the more susceptible is key
It is crucial to consider the influence of genetics when examining the connection between endometriosis and cancer. Being aware of genetic predispositions and family history plays a vital role in detecting and thwarting cancer early among women affected by endometriosis. For example, if you have endometriosis and a history of ovarian, endometrial, or colorectal cancer, you may consider yourself at a higher risk for incidence. This isn't to scare you! But to help you make the best choices in being proactive about screening.
For example, colon cancer runs strong in my family line, so I chose to start colonoscopy at the age of 38 rather than 50 for proactive screening.
Symptoms Overlap: Endometriosis vs. Cancer
How to do you know how to be aware? Managing endometriosis can be complicated due to the similarity of its symptoms with those found in certain cancers! Pelvic pain, bloating, painful menstruation, and discomfort during intercourse are common manifestations that both endometriosis and ovarian cancer share. Consequently, these shared signs may result in delays when diagnosing and providing the proper treatment.
Additional indicators like unexplained weight loss or changes in eating habits should prompt individuals to seek medical advice if they emerge alongside other endometrial symptoms. It’s noteworthy that women who suffer from endometriosis also experience elevated levels of anxiety and depression, which could potentially mask some symptoms adding another layer of complexity to clinical assessments.
Establishing a precise diagnosis is crucial for successful intervention and ongoing care once either condition is identified.
Prevention? The Heal Endo Approach is helpful!
If it's a body-on-fire internal ecology that sets the stage for both endometriosis and cancer risk, we can ruduce the risk by altering the body ecology back to a state of homeostasis. Exactly what I explain in my book.
Leading a physically active lifestyle and keeping one’s weight in check can markedly lower the chances of contracting endometrial cancer...and endometriosis. We see that eating foods that lower inflammation and support healthy immune function reduce cancer risk, and endomeriosis risk. We see that regulating the nervous system, having close friendships, being outside, and sleeping well all work to reduce endometriosis severity, and cancer risk.
Indeed, there are many (many) things within our control when taking our disease burden into consideration.
Of course there is a pressing need to delve deeper into understanding how endometriosis may be connected to cancer, which would help refine screening techniques and create more effective measures to prevent it. By taking steps towards vigilant health management, we with endometriosis can enhance their prognoses while also gaining reassurance regarding their condition.
