We all know at this point that the key to breast cancer survival is early detection. While a big part of this involves self-exams, another is getting your regularly scheduled mammogram. Mammograms have been considered the number-one test to detect breast cancer for quite some time now. Do enough digging around online, however, and you will find those who question both their efficacy and safety. Let’s break down the mammogram and all of its pros and cons so that you can feel confident in the decisions you make for your own health.
The Basics on Mammograms

Mammograms, a go-to technique for breast cancer screening, utilize low-dose X-rays to detect abnormalities. As with most medical procedures, they are not without their shortcomings. While offering the benefit of potentially spotting cancer at its earliest stages, there are associated risks. Long-term exposure to radiation from frequent mammograms may incrementally escalate the risk of radiation-induced cancers. Additionally, false positives, particularly common in younger women with dense breast tissue, can lead to undue anxiety and unnecessary follow-up testing. So the question remains, are mammograms safe, who should be getting them and how often, how can you minimize your own risks, and are there alternatives? Let’s dive in.
Navigating Overdiagnosis and Overtreatment

One contentious topic surrounding mammograms is overdiagnosis, especially in cases like ductal carcinoma in situ (DCIS), where the detected cancer may not pose a significant threat. The problem here is that this could result in overtreatment, exposing patients to the side effects of various cancer treatments that might not have actually required any intervention at all. Certain treatments, such as chemotherapy and radiation, can actually increase your risk of secondary cancers down the line. If it is not necessary to receive these treatments, why take the risk? Moreover, dense breast tissue can hinder the effectiveness of mammograms, as both dense tissue and tumors appear white on X-rays, potentially leading to missed diagnoses. This can cause undue stress for the patient and, again, expose them to unnecessary treatment risks.
Separating Facts from Fiction
Beyond the mammogram’s capacity to be wrong, you can find many places online where people are debating their safety. Many of these claims regarding mammograms lack concrete evidence. For instance, the assertion that mammograms increase the risk of cancer in individuals with BRCA mutations (mutations to the genes responsible for suppressing tumors from growing) is not supported by scientific data. Furthermore, while the 2014 Cochrane Review cast doubt on the mortality-reducing potential of mammography, other studies suggest modest benefits in terms of breast cancer survival rates. Claims about the compression that patients experience during mammograms causing cancer cell spreading also remain unsubstantiated.
Alternative Screening Methods: Exploring Thermography and Ultrasound

In the pursuit of more patient-friendly screening options, thermography and ultrasound have emerged as potential alternatives to mammograms. However, the efficacy and reliability of these methods remain under scrutiny.

Thermography

Thermography is a non-invasive imaging technique that captures infrared radiation emitted from the body. This allows for the detection of heat patterns that may indicate underlying health conditions. The main benefit of thermography is its ability to provide early detection of health problems, such as breast cancer, without exposure to radiation. This makes it a safer option for monitoring conditions like breast abnormalities or inflammation, particularly for at-risk women who may be too young to receive a mammogram. That being said, thermography still has risks, including the possibility of false positives or negatives. While it can be a less invasive way to monitor at-risk individuals, it should not be used as a replacement for traditional diagnostic methods like the mammogram. Rather, it can be used to signal that there is a need for a mammogram.
Ultrasound

Ultrasound, not unlike those used to check up on a pregnancy, can also be used to detect breast cancer. Ultrasound for breast cancer is a non-invasive imaging technique that uses sound waves to create detailed pictures of the inside of the breast. This method is particularly beneficial for detecting breast changes, such as things like fluid-filled cysts, which may be harder to identify on mammograms. Ultrasound are not typically used in routine breast cancer screenings but they can be valuable for examining lumps, particularly those that are palpable but not visible on the mammogram. They are also highly useful for women with dense breast tissue, as they help to add visualization of abnormal areas that may be hard to discern on mammograms. Ultrasounds are able to differentiate between fluid-filled masses like cysts, which are normally non-cancerous, and solid masses that may require further investigation. They can help to guide biopsy needles to obtain tissue samples for breast cancer testing and swollen lymph nodes. Despite all of their pros, however, ultrasound has limitations in detecting certain types of breast abnormalities and therefore can not replace the necessity for traditional diagnostic methods like mammograms.
Making Informed Choices
The bottom line remains that mammograms are not just a valuable screening tool, they are the gold standard in terms of breast cancer detection. They are especially recommended for women between the ages of 50 and 74, who are at the highest risk of developing breast cancer. It is crucial for individuals to weigh the benefits of early detection against the risks of false positives and potential overdiagnosis. For example, if you are someone who has various risk factors, such as family history, smoking, or long-term use of hormonal birth control, you may wish to start your screenings earlier than women who do not have these risk factors. While exploring alternative screening methods is understandable, women should engage in informed discussions with healthcare providers to tailor screening modalities to their individual risk profiles and preferences.
