Mammograms: Preventing or Causing Cancer? A Holistic Medicine Perspective
Breast cancer is one of the most common cancers among women worldwide, and early detection is crucial for improving survival rates.
Mammography, a widely used screening tool, has been credited with reducing breast cancer mortality by detecting tumors at earlier, more treatable stages. However, the effectiveness and safety of mammograms have been subjects of debate.
More and more research shows that mammograms may do more harm than good, potentially increasing cancer risk due to radiation exposure, causing unnecessary stress, and leading to overdiagnosis and overtreatment.
What does this mean? Women are getting chemotherapy, mastectomies, and radiation when there is no cancer present!
In this blog, I’ll delve into the arguments for and against mammograms, exploring alternative screening methods and considering a holistic approach to breast health.
The Case for Mammograms
Benefits of Mammograms
Early Detection: Mammograms can identify breast cancer early, often before symptoms develop, leading to early intervention and potentially better outcomes. (1)
Reduced Mortality: Some studies suggest that regular mammograms reduce the risk of dying from breast cancer, particularly in women aged 50-74, while other studies show the opposite. (2)
Insurance Coverage: Mammograms are widely covered by health insurance, making them accessible to many women.
Concerns About Mammograms
Despite these benefits, mammograms are not without significant risks and drawbacks, which have led to a growing debate in the medical community.
Overdiagnosis and Overtreatment
One of the primary concerns is overdiagnosis—detecting cancers that would not have caused harm during the patient’s lifetime. This leads to overtreatment, including unnecessary surgeries, radiation, and chemotherapy, which carry their own risks and side effects. (
False Positives: Mammograms can yield false-positive results, leading to unnecessary biopsies, surgeries, and treatments, causing undue stress and physical harm. A study published in the BMJ highlighted the psychological and physical impacts of false-positive mammogram results. (3)
Radiation Exposure: While the radiation dose from a single mammogram is low, repeated exposure over many years can accumulate, potentially increasing the risk of developing radiation-induced breast cancer. (2)
Tumor Rupture: The compression of the breast during a mammogram might cause tumor rupture and the spread of cancerous cells, posing a serious risk to patients. (4)
In a 2011 Chochrane review, the claim that the introduction of mammographic breast cancer screening might have caused net harm for up to 10 years after the start of screening was supported. (5)
Alternatives Screening Tools to Mammography
Thermography
Thermography is a non-invasive imaging technique that detects heat patterns and blood flow in body tissues. Proponents argue that it can detect breast cancer earlier than mammography without exposing patients to radiation. However, thermography is not widely accepted as a standalone diagnostic tool due to concerns about its accuracy and the lack of standardization in its use, i.e. it is often not covered by insurance. (6, 7)
Ultrasound and MRI
Ultrasound and MRI are additional imaging methods that can be used to screen for breast cancer.
Ultrasound (US) is often used as an adjunct to mammography, particularly in women with dense breast tissue. Studies have shown that USs are an effective primary detection tool as an alternative to mammograms. (8)
Advancement in US technology with Quantitative Transmission (QT) ultrasounds demonstrate improvement in the imaging performance compared to older US technology and has shown promise as a breast imaging modality. (9)
MRI, while more sensitive than mammography, is expensive and may not be accessible to all patients.
Both methods can help reduce the risk of radiation exposure. Generally, these methods of screening are not standard of care and may not be covered by insurance.
Beyond Imaging: Functional Medicine Approach to Breast Cancer Diagnostics
While screening can play an important role in detecting cancer, functional medicine aims to identify and address the root causes of diseases, including cancer.
The importance of assessing the internal environment, can not be overstated in the prevention, treatment, and remission of breast cancer. Cancer is more likely to grow and thrive under certain conditions.
Whether you're wanting to prevent cancer or you’ve overcome cancer and want to stay in remission, the following discussion will give you a better understanding of the factors that contribute to breast cancer development and what you can do to change your risks and take a proactive approach.
Understanding various underlying root causes can help your functional medicine doctor tailor a personalized treatment plan to restore a balanced environment within your body.
Metabolic Dysfunction in Cancer
Metabolic dysfunction is increasingly recognized as a critical factor in cancer development and progression. Cancer cells exhibit altered metabolism, known as the Warburg effect, where they rely heavily on glycolysis for energy production even in the presence of oxygen. (10)
This shift allows cancer cells to proliferate rapidly but also makes them dependent on glucose and other nutrients. Metabolic dysfunction can create an environment conducive to cancer by increasing oxidative stress, promoting inflammation, and disrupting normal cellular processes.
Conditions such as obesity, insulin resistance, and metabolic syndrome are linked to higher cancer risk due to their roles in fostering a pro-inflammatory state and hormonal imbalances. (11)
Addressing metabolic dysfunction through dietary changes, intermittent fasting, regular exercise, and targeted therapies can be a pivotal strategy in cancer prevention and treatment, potentially hindering cancer cell growth and improving patient outcomes.
Screening for Inflammatory Markers and Metabolic Dysfunction
In the realm of functional medicine, lab testing for inflammatory markers and insulin resistance offers crucial insights into breast cancer risk.
Chronic inflammation has been linked to cancer development and progression, making markers such as hsCRP (high sensitivity C-reactive protein), ESR (erythrocyte sedimentation rate), and ferritin valuable indicators of underlying inflammatory processes.
Additionally, insulin resistance, a condition where cells become less responsive to insulin, has been associated with an increased risk of breast cancer. (12)
Tests that measure fasting insulin and glucose levels, glucose tolerance, and HbA1c can help identify insulin resistance early.
By understanding these basic blood markers, your functional medicine doctor can implement targeted interventions such as diet, lifestyle, supplements, herbs, and acupuncture to reduce inflammation and improve insulin sensitivity, potentially lowering the risk of breast cancer and improving overall health outcomes.
Toxic Burden and Breast Cancer
Toxicity screening plays a vital role in understanding the environmental and internal factors contributing to breast cancer risk.
Exposure to environmental toxins such as heavy metals (lead, mercury, cadmium), endocrine disruptors (found in plastics, pesticides, unfiltered water, and personal care products), and other carcinogens can significantly increase the likelihood of developing breast cancer. (13,14)
These substances can interfere with hormonal balance, promote oxidative stress, and damage DNA, leading to the initiation and progression of cancerous cells.
Comprehensive toxicity screening can identify the presence and levels of these harmful agents in the body, allowing for targeted detoxification strategies.
By addressing and reducing toxic burden, individuals can mitigate one of the crucial risk factors associated with breast cancer, paving the way for more effective prevention and holistic health maintenance.
Immune System Dysfunction and Breast Cancer
Immune system dysfunction plays a critical role in the development and progression of breast cancer. A healthy immune system is essential for identifying and eliminating cancerous cells, maintaining tissue homeostasis, and preventing tumor growth.
However, when the immune system is compromised or dysregulated, its ability to recognize and destroy abnormal cells is significantly weakened.
This dysfunction can result from chronic inflammation, autoimmune conditions, or an imbalance in immune cell populations, such as T cells, B cells, and natural killer (NK) cells. (15)
Additionally, tumor cells can exploit these weaknesses by evading immune detection and creating an immunosuppressive microenvironment that further hinders immune response.
Understanding and addressing immune system dysfunction through diagnostic testing and targeted therapies can enhance the body's natural defenses against breast cancer, improve patient prognosis, and support long-term health.
Genetics: MTHFR and COMT Mutations in Breast Cancer
Genetic screening for MTHFR (methylenetetrahydrofolate reductase) and COMT (catechol-O-methyltransferase) single nucleotide polymorphisms (SNPs), i.e. mutations, offers valuable insights into an individual's susceptibility to breast cancer.
The MTHFR gene plays a crucial role in folate metabolism and DNA methylation, processes essential for maintaining genetic stability and preventing mutations. Mutations in MTHFR can lead to elevated homocysteine levels (measured in basic blood work) and impaired detoxification pathways, increasing cancer risk. (16)
Similarly, the COMT gene is involved in the breakdown of estrogen and catecholamines. Variations in COMT can affect estrogen metabolism, leading to an accumulation of potentially carcinogenic estrogen metabolites. (17)
Understanding these genetic polymorphisms allows for personalized interventions, such as specific dietary supplements or lifestyle modifications, to mitigate these risks and support optimal metabolic function.
This genetic insight is particularly important in identifying those at higher risk of breast cancer and developing preventive strategies and personalized treatments for them .
Advanced Functional Medicine Lab Tests
By utilizing advanced lab testing, functional medicine practitioners can gain a deeper understanding of a patient’s overall health and specific imbalances that may contribute to breast cancer and other disease risks.
Three key functional medicine tests used for comprehensive diagnostics are Nutreval, DUTCH, and Lymphocyte MAP testing.
Nutreval Testing
Nutreval (Nutritional Evaluation) testing provides an in-depth analysis of a patient’s nutritional status, various toxicities, and important relative genetic markers.
This test assesses a wide range of biomarkers, including vitamins, minerals, amino acids, fatty acids, and antioxidants. By evaluating these markers, Nutreval testing can reveal deficiencies, imbalances, and potential toxicities that may contribute to breast cancer risk and overall health issues. For instance, deficiencies in essential nutrients like vitamin D, magnesium, and omega-3 fatty acids have been linked to increased cancer risk. (18)
Nutreval testing helps identify nutrient deficiencies, toxic burden, and genetic polymorphisms allowing for targeted nutritional and lifestyle interventions and personalized approach to care.
DUTCH Testing
DUTCH (Dried Urine Test for Comprehensive Hormones) testing provides a comprehensive assessment of adrenal and sex hormones, including their metabolites. Hormonal imbalances play a significant role in the development and progression of breast cancer. DUTCH testing evaluates levels of all estrogens, progesterone, androgens, cortisol, other hormones, and their metabolites providing insights into hormonal health and potential dysregulation.
By understanding these hormonal patterns, practitioners can develop personalized treatment plans to restore balance and reduce cancer risk. For example, elevated estrogen levels and poor estrogen metabolism have been associated with an increased risk of breast cancer. (19)
DUTCH testing can identify these issues and guide interventions such as dietary changes, supplementation, and lifestyle modifications.
Lymphocyte MAP by Cyrex Labs for Immunology Testing in Breast Cancer
The Lymphocyte MAP test offers a comprehensive analysis of the immune system's functionality, which is crucial in understanding breast cancer risk and progression.
This advanced immunology test evaluates the status and performance of various lymphocyte subsets, including T cells, B cells, and natural killer (NK) cells. (20)
These components play essential roles in identifying and destroying cancer cells, maintaining immune surveillance, and orchestrating immune responses.
By detecting imbalances or dysfunctions within these lymphocyte populations, the Lymphocyte MAP can reveal underlying immune deficiencies or dysregulations that may contribute to breast cancer development.
Early identification of such immune irregularities allows for targeted interventions to bolster the immune system, enhancing its ability to combat cancer and improving overall outcomes for breast cancer patients.
A Holistic Approach to Breast Health
Lifestyle Modifications
A holistic approach to breast health emphasizes the importance of lifestyle modifications in reducing cancer risk. Maintaining an anti-inflammatory diet rich in organic fruits, vegetables, wild-caught fish, and grass-fed/finished meat, engaging in regular physical activity, and avoiding smoking and excessive alcohol consumption can all contribute to lower breast cancer risk .
Stress Reduction and Emotional Well-being
Chronic stress has been linked to an increased risk of cancer. (21)
Practices such as yoga, meditation, and mindfulness can help manage stress and improve emotional well-being. Supporting mental health is a crucial component of holistic health and can positively impact overall cancer risk .
Acupuncture
Acupuncture, a traditional Chinese medicine practice, involves inserting thin needles into specific points on the body to balance energy flow. It is increasingly recognized for its role in supporting overall health, including breast health.
Acupuncture can help manage symptoms and side effects associated with cancer treatments, such as (22):
Pain
Fatigue
Nausea
Peripheral neuropathy
Lymphedema
Dry mouth
Hot flushes
Insomnia
Moreover, it can reduce stress and anxiety, which are known to negatively impact immune function and overall well-being.
Additionally, acupuncture has been shown to support immune system function and regulate endocrine activity, both crucial for maintaining hormonal balance and preventing cancer progression.
Incorporating acupuncture into a holistic health plan may support the body’s natural healing processes and enhance quality of life. (23)

Regular Self-Examinations and Professional Check-Ups
While mammograms are considered the standard of care, this method of detection is highly debated. Other screening tools are available and may be worth considering as a method of detection.
Regular self-examinations can help women become familiar with their breasts and notice any changes early.
Additionally, regular check-ups with an ObGyn as well as establishing a relationship with a functional medicine doctor.
Your functional medicine doctor can work with you on all stages of breast cancer, i.e. prevention, cancer treatment, and remission, to address root imbalances that may be present and pave a road for long-term health.
Conclusion
The debate over the efficacy and safety of mammograms continues, with valid arguments on both sides. While mammograms can detect cancer early and are considered the standard of care and therefore covered by insurance, they also pose risks such as radiation exposure, overdiagnosis, overtreatment, and psychological stress.
Exploring alternative screening methods and adopting a holistic approach to breast health can provide a more comprehensive strategy for preventing and managing breast cancer.
Ultimately, the decision to undergo mammography should be individualized, taking into account personal risk factors, preferences, and the guidance of a trusted healthcare provider.
