The most recent study on mammograms that finds no benefit is one of the largest and longest. According to the New York Times,
“One of the biggest and most meticulous studies of mammography has never done, with the participation of 90,000 women and last a quarter century, has added powerful new doubts about the value of screening for women of any age.
“We found that mortality rates for breast cancer and all causes cancer were the same in women who received mammograms and those who did not and the projection had damage :. One of every five cancers detected by mammography and treated was not a threat to women’s health and did not need treatment such as chemotherapy, surgery or radiation. “
Where is the wisdom in the use of cancer screening causes cancer?
Besides the damage caused by overtreatment, irradiating the breasts for decades is questionable, at the very least, given that ionizing radiation is associated with cancer development.
The results, which were published in the British Medical Journal ( BMJ) in 2012 suggest that women with mutation in the gene called BRCA1 / 2 are especially exposed to the possibility of being affected by radiation-induced cancer.
It was also discovered that radiation-induced cancer was dose-response, which means that the higher the dose, the higher the risk of developing cancer.
As concluded by the authors,
“The results of this study support the use of techniques of non-ionizing radiation image (such as magnetic resonance imaging) as the main tool for monitoring the young women with BRCA1 / 2 “
At this point, the controversy regarding mammograms is pretty much resolved, at least is published research is considered.
Increased mammography study to date not find Benefit
The study published in the British Medical Journal ( BMJ) involved a screening period of 5 years with a follow-up of 25-year period. The women were assigned to receive an annual physical breast examination or annual mammogram.
Up to 3,250 of the women who received mammography were diagnosed with breast cancer, as opposed to 3,133 in the breast examination without mammography group.
The authors concluded that “. the annual mammography in women aged 40-59 years of age does not reduce mortality breast cancer beyond physical examination or special care of adjuvant therapy for breast cancer is free. overall, 22 percent of screen-detected invasive breast cancer is over-diagnosed, which represents a over-diagnosed breast cancer for every 424 women who received mammography screening at trial. “
False negative-Another danger of mammography
In addition to the false positives that lead to unnecessary treatment, mammography is also associated with the risk of false negative. According to the National Cancer Institute (NCI), mammograms lose 20 % of breast cancers that are present at the time of detection.
3D-La crazy tomosynthesis alternative that increases their risk even more
Instead of coming clean about the dangers of mammography, the industry came with a “new and improved” mammography in 2011 called tomosynthesis 3D. However, turns out that the doses of radiation are higher compared to a standard mammogram. According to Dr. Susan Love, tomosynthesis exposes approximately twice the amount of radiation compared to a standard mammogram.
