Since the early 1980s and still, to this day, the goal of mammograms has been early breast cancer detection. With that being said, women are often encouraged by persistent advertising campaigns to participate in routine mammogram screening programs, starting around their 40th birthdays.¹ Those with a history of breast cancer in the family are encouraged to get a yearly mammogram. Without a family history of breast cancer, in most countries that have screening programs, women 50 and up are urged to have a mammogram every two years.

 

But while these screenings play a role in catching cancer early, they also involve low levels of radiation and breast trauma, raising important questions about their overall safety. What does “low-level” radiation actually mean, and what are the potential risks over time? How damaging is breast trauma and what are the consequences? With millions of women relying on mammograms as part of their health routine, understanding the benefits and risks is essential. So, just how safe is mammography? Let’s dive deeper into the science, benefits, and complexities of mammography.

 

What is Mammography?

In simple terms, a mammogram is an X-ray designed to examine breast tissue in the hope of preventing breast cancer. During the procedure, the breast is flattened and compressed between two plates to spread the tissue, allowing the X-ray to capture images. Usually, each breast is X-rayed twice giving doctors two views to spot even tiny abnormalities.² 

 

While mammograms may be helpful for early cancer detection, they also raise some serious concerns, mainly around radiation exposure, potential trauma from compression, and even the possibility of over-treatment. In this article, we will talk about some of these concerns in more detail. 

 

X-Ray and Radiation

As mentioned earlier, mammography involves a series of X-rays. But what exactly is an X-ray? X-rays are a type of electromagnetic radiation with very short wavelengths and high energy, allowing them to pass through various materials, including human tissues. This ability allows X-rays to view the body’s internal structures. Although a single mammogram supposedly involves a relatively low level of radiation, this low-dose exposure can become a concern when considering cumulative exposure over time. Due to their high energy, X-rays can pose health risks with excessive exposure or even a single dose.

 

Radiation is well known to be harmful to humans because it carries energy that can damage or alter cells, including DNA, disrupting normal cellular functions. Because of this, damage can lead to a range of serious health issues and even cause cancer.

 

Understanding Radiation Types: Ionizing vs. Non-Ionizing

Radiation comes in two forms: ionizing and non-ionizing. However, there’s an important distinction. Ionizing radiation, the type of radiation performed with mammography has enough energy to remove tightly bound electrons from atoms, creating ions. This process can cause significant damage to cells and DNA, which may increase cancer risk. On the other hand, non-ionizing radiation includes lower-energy forms like visible light and microwaves, which do not carry the same risk of cellular damage. While earlier claims equated the radiation from a mammogram to six months of natural background radiation, newer figures suggest it is only two months—raising questions about changing standards or potential discrepancies in the information. Whether this reflects evolving scientific assessments or unclear data from the outset, one thing remains clear: understanding the true risks and benefits is crucial for making informed health decisions.³

 

Women are often assured that mammogram radiation is minimal, yet the cumulative effects of ionizing radiation from medical imaging—such as mammograms, dental X-rays, or CT scans—can add up over time. Low-risk women may be recommended mammograms every few years, while those with a family history are often advised to screen annually. However, it’s vital to question whether these risks, particularly for those who recently had other imaging procedures, are fully disclosed to support informed decision-making. 

 

Mammography Around the World: Participation rates

In many countries, a substantial number of eligible women participate in regular breast cancer screening programs. For instance, in Canada⁴ (2022) 78.5% of women aged 50-74 reported having a mammogram within the previous three years, and in 2021 in the United States, about 75.9% of women in this age group had a mammogram in the previous two years.⁵ Participation rates in Europe⁶ vary. In 2021, Denmark reported a screening rate of 83.0% for women aged 50 to 69, Finland had 82.2%, and Sweden 80.0%. Malta and Slovenia followed closely with rates of 77.8% and 77.2%, respectively.⁷

 

Women assume that screening programs save lives and that the advantages of screening must be crystal clear since so many people participate in them. With the establishment of these programs, one might expect a notable decrease in both advanced-stage cancer diagnoses and breast cancer mortality. But is this truly the case? Do regular mammograms effectively reduce the likelihood of developing advanced breast cancer, and do they save lives? 

 

The rationale for widespread mammography is that early detection of potentially fatal breast cancers enables earlier and more effective treatment. But there is a potential drawback: mammography can detect some early-stage cancers that will never progress to cause symptoms–a ‘’phenomenon’’ often referred to as overdiagnosis, which we will discuss later in this article.⁸ In such cases, the emotional, financial, and physical costs of a cancer diagnosis and any subsequent treatments occur without any corresponding health benefit. Because it is hard to tell which women will be harmed by their cancers, there is a tendency to treat all women as if their cancers will be lethal. Even if the initial cancer would have never proven life-threatening, exposure to chemotherapy, radiotherapy, and surgery can potentially lead to new conditions, and even to new fatal cancers.⁹

 

Screening Side Effects

While examining the use of mammograms, it’s important to consider their risks and side effects. This topic raises a couple of important questions: Are women being adequately informed about the side effects of screening? Could breast compression during mammograms pose risks beyond just discomfort? While there may be no proof that compression causes cancer, evidence is mounting that compression may indeed play a role in cancer development. 

 

The Physical Impact of Compression: Breast Trauma

Let’s explore the most obvious but often overlooked issue with mammograms: the compression applied during the procedure. For many women, the pressure of compression is uncomfortable and often very painful.¹⁰ To obtain a clear image, mammograms apply substantial pressure, which can reach up to 45 pounds, to spread the breast tissue. This compression can sometimes lead to bruising or the breakage of blood vessels just beneath the skin, particularly in women with sensitive tissue.

 

While medical sources¹¹ commonly label concerns about compression-related cancer risk as “myths” and assure women that “there is no scientific evidence that compression of the breast causes cancer” or that it “cannot cause cancer to spread,” emerging research suggests a need to explore potential effects of compression on breast tissue more thoroughly.

 

Additionally, some researchers are exploring whether repeated compression over time might impact breast tissue at the cellular level or even contribute to tissue changes, particularly for those undergoing regular mammograms. Whether this forceful compression could potentially “wake up” dormant cells or affect tissue structure in other ways is still under study, but these potential risks highlight the need for ongoing evaluation of mammogram techniques to ensure both safety and effectiveness.¹²

 

Interval Breast Cancers: A Potential Link?

 

Interval breast cancers (IBCs)¹³—those that develop between regular mammograms—make up about 25% of cases detected in screening programs. These cancers are often aggressive, diagnosed at advanced stages, and are frequently HER2-positive (a type of breast cancer characterized by a protein that promotes cancer cell growth).¹⁴ Research suggests mammogram compression may stimulate dormant cancer cells, with studies in mice showing tissue injury can accelerate tumor growth.  

 

One case from 2008 involved a woman, without any previous breast cancer history, who developed an aggressive tumor after a painful mammogram caused a hematoma. Despite treatment, she passed away in 2012. This case highlights the risks of mammogram compression, which can cause tissue damage or hematomas, potentially accelerating tumor growth.¹⁵  But how many other cases remain unheard or dismissed? How many women have been encouraged by advertisements and healthcare providers to undergo similar procedures, only to face comparable outcomes? While the full extent may never be known, one thing is certain: women deserve the right to voice their experiences, discuss the pain they endure during these procedures, and share their concerns openly, without fear of dismissal.

 

An article from 2012 in The Lancet (a world-leading general medical journal) stated: "For every 10,000 UK women aged 50 years invited to screening for the next 20 years, 43 deaths from breast cancer would be prevented, and 129 cases of breast cancer, invasive and non-invasive, would be overdiagnosed; that is, one breast cancer death prevented for about every three overdiagnosed cases identified and treated."¹⁶

 

Overdiagnosis and Overtreatment: Are We Treating Too Much?

Routine mammography raises concerns about overdiagnosis and overtreatment, with studies estimating that up to 20% of breast cancers detected, such as slow-growing tumors or ductal carcinoma in situ (DCIS), may not require treatment.¹⁷ Overdiagnosis often leads to unnecessary interventions like surgery, radiation, or chemotherapy, with associated risks. Personalized screening guidelines, using tools like ultrasound or MRI, could help distinguish aggressive cancers from less harmful ones, reducing unnecessary treatments and empowering women to make informed health decisions.

 

Technological Advances in Mammography: Toward Safer and More Effective Screening

In response to the limitations and concerns associated with traditional mammography and with technological and medical evolution, scientists are exploring innovative methods of breast cancer screening that aim to reduce or even eliminate radiation exposure altogether. Here are some of the alternatives currently being developed, from radiation-free to minimum radiation screening methods. They might not all be completely harmless, but many have less radiation than the standard mammography.

 

Ultrasound: A Closer Look Without Radiation

Many centers now use ultrasound as a radiation-free supplement to 3D mammography, particularly for women with dense breast tissue, young women, and those at high risk who undergo frequent screenings. High-frequency sound waves provide clearer images of dense tissue, avoiding the ionizing radiation concerns of repeated mammograms. Studies in European Radiology show ultrasound is more sensitive than mammography for detecting early-stage cancers in high-risk women under 40, often identifying small lesions missed by mammograms.¹⁸

 

Thermal Imaging

Thermography is a non-invasive, radiation-free method that detects heat patterns on the skin. While it doesn’t diagnose cancer, it can reveal temperature changes linked to abnormal activity. Though less sensitive than mammography and often costlier, future advancements may enhance its value, particularly for women requiring frequent screenings.

 

Other Screening Methods: MBI, EIS, Elastography, Optical Imaging

Emerging breast cancer screening technologies aim to enhance detection while reducing risks. Electrical Impedance Scanning (EIS) measures tissue conductivity without radiation, showing promise as a supplementary tool. Molecular Breast Imaging (MBI) detects tumors more effectively in dense breast tissue than traditional mammograms, using less radiation, while optical imaging and elastography provide non-invasive options to evaluate flagged areas with greater precision.¹⁹

 

Understanding Dense Breast Tissue: A Factor in Screening Choices

Dense breast tissue, which has more fibrous and glandular tissue than fat, can obscure abnormalities on mammograms and is also linked to higher breast cancer risk. This has led to recommendations for women with dense breasts to explore supplemental screenings, like ultrasound or MRI. Legislation in many U.S. states now ensures women are informed about their breast density, encouraging discussions with healthcare providers for better-informed decisions.^{20, 21}

 

Breast Cancer Prevention: Holistic and Medical Approach

Preventing Cancer through Hormones, Vitamin D, and Insulin 

 

Focusing on key factors can greatly reduce breast cancer risk. Hormone replacement therapy (HRT) and birth control pills, once considered safe, are now linked to significantly higher risks, while bioidentical hormones offer safer alternatives. One study made the startling discovery that HRT with either estrogen alone or estrogen-plus-progestin was associated with a 70 percent increase in breast cancer risk when the therapy was taken for five years within the six years preceding the cancer diagnosis!^22, 

 

Maintaining vitamin D levels between 60–80 ng/ml and fasting insulin levels around 2–3 can further lower risks, as both play critical roles in prevention.²³

 

 

Preventing Cancer Through Mindful Living

Breast cancer is a daunting diagnosis, but the good news is that our lifestyle choices can play a powerful role in reducing risk and supporting overall health. Understanding why we get sick, is a vital first step in making better choices to prevent disease. Incorporating the eight foundational principles—Sunlight, Temperance, Rest, Exercise, Nutrition, Good Air, Trust in God, and Hydration—offers practical strategies for overall well-being, as outlined in The 8 Laws of Health. Together, these approaches provide a clear path to lowering the risk of breast cancer and improving overall vitality.

 

Sunlight

Moderate sun exposure helps your body produce vitamin D, which is essential for bone health, immunity, and mood regulation. Spending 15–20 minutes in the sunlight daily, especially in the morning can help with longevity. Exposing yourself to bright sunlight boosts your melatonin levels and helps to protect against breast cancer. For more on the Benefits of sunlight check our detailed article on Vitamin D and Sunlight!²⁴

 

Temperance

Practicing moderation and avoiding harmful substances like alcohol, tobacco, and processed foods is vital for overall health. Intermittent fasting, which activates autophagy—a natural cellular clean-up process—has been linked to longevity and cancer prevention by recycling damaged cell components.²⁵ To dive deeper into the importance of temperance and how practices like fasting contribute to a healthier life, explore this insightful article on Your Health and the Virtue of Temperance³⁰ at Amazing Health! 

 

 

Rest

Adequate sleep, particularly before midnight, is vital for the body’s repair and regeneration, as processes like tissue repair, hormone regulation, and immune function reach their peak during this time. A study in the Journal of the American Heart Association found that sleeping less than six hours increases the risk of cancer and early death, particularly in those with chronic conditions.²⁶ Optimizing melatonin production is equally important and surprisingly simple: sleep in complete darkness, use a red penlight if necessary, and avoid blue LED lights from devices like alarm clocks.³² For tips on improving sleep quality and understanding why sleep is essential for health, explore the article Why Do We Need Sleep? Sleep isn’t just rest—it’s your body’s key to renewal and resilience!

 

 

Exercise

Studies have shown that regular exercise boosts circulation, strengthens immunity, and helps control weight. Maintaining a healthy weight is especially important, as excess body fat can raise estrogen levels, increasing the risk of breast cancer. Incorporating at least 30 minutes of moderate activity most days can make a significant difference in overall health, as highlighted in the article Why Is Physical Activity Important? A consistent exercise routine is a powerful step toward a healthier, more vibrant life.

 

 

Nutrition

A plant-based diet rich in fruits, vegetables, whole grains, nuts, and seeds is essential for reducing inflammation and cancer risk. Pairing foods correctly can enhance digestion and nutrient absorption, as explained in our detailed article about Plant-Based Food Combining. Increase your intake of healthy omega-3 fats, eliminating harmful trans fats and reducing excess omega-6 fats. This balance is essential for preventing vitamin D-sensitive breast cancer.²⁷  For more nutritious tips on optimizing your diet for long-term health, explore Nutrition for Maximum Health. Small changes can make a big difference!

 

 

Good Air

Fresh air revitalizes the lungs, boosts oxygen levels, and supports overall health. Low oxygen levels (hypoxia) are linked to cancer progression, but practices like deep breathing, regular exercise, and spending time in nature help reduce hypoxia and strengthen immune function. For insights into the importance of fresh air, watch Walt Cross’s video Breathe Fresh Air. Additionally, learning techniques like Diaphragmatic Breathing, can further enhance oxygen intake and lung function. Embrace the healing power of nature and proper breathing—it’s a simple yet powerful way to boost your well-being.

 

 

Trust in God

Faith and a positive outlook are powerful in reducing stress and anxiety, fostering a sense of peace that enhances overall well-being. Trust in God brings hope and comfort, as beautifully expressed by a Christian author: "Faith in God’s love and overruling providence lightens the burdens of anxiety and care. It fills the heart with joy and contentment in the highest and holiest activities."²⁸ This timeless insight underscores the profound connection between faith and a balanced, healthy life.

Hydration

Water is the source of life, essential for maintaining healthy cells, aiding digestion, and flushing out toxins. Every organ relies on proper hydration to transport nutrients, regulate temperature, and eliminate waste, while even mild dehydration can affect energy, focus, and physical performance.

Why Prevention Is the Cure We’ve Been Overlooking

Preventing breast cancer starts with a mindset shift—from relying mainly on screenings to embracing a proactive, health-focused lifestyle. While mammograms and other screening tools are often emphasized, they come with risks like overdiagnosis and unnecessary treatments. Prevention, not just detection, is where our focus should be, empowering us to make intentional, informed choices.

 

A balanced, plant-based diet, regular exercise, proper hydration, sunlight, and good sleep can do wonders to lower cancer risks while boosting overall health. Add stress management and a positive outlook, and you’re setting yourself up for resilience and vitality.

 

If cancer is found, it’s important to remember that traditional treatments like chemotherapy and radiation aren’t the only options. Many people have successfully treated breast cancer 100% naturally, proving that healing without harmful side effects is possible. The medical industry often overlooks natural treatments, but they can provide real hope and healing by working with the body instead of against it.
