On October 15, World Breast Day is celebrated. We decided to check the widespread belief that wearing a too close bra can lead to an oncological disease.

About the connection between the occurrence of the disease and the incorrectly selected bra They say Not only far -medical sites and lower shops Bellyabut also rather authoritative professionals. For example, a specialist in the capital's health department Andrei Trulynikov He thinks: “If parts of the bra are cut into the body, soft tissues and blood vessels are squeezed, the nerve fibers can suffer. This can provoke numbness of the hands or a decrease in their sensitivity. Other symptoms of a crushing bra - headaches, pain in the neck and chest. The axillary depressions are the location of several lymph nodes. Their compression leads to stagnation of lymph, which provokes the accumulation of cells of cells. This can provoke allergies, hypertension and even cancer. Compression in the chest and mammary glands also leads to stagnation in the circulatory system. The blood flow is disturbed, which delivers oxygen to the cells and transporting carbon dioxide from them. Stagnation of blood very negatively affects the condition of the walls of blood vessels. ”

Breast cancer - the most common The type of cancer and the main cause of the mortality of women among all cancer. In 2020, it was found in more than 2.3 million women, 685,000 died of this disease. Breast cancer occurs in the cells of the epithelium of the mammary ducts in most cases (85%) or in slices (15%) of the glandular tissue of the mammary gland. Mention of pathology is even in Papyrus Ancient Egypt.

To reliable risk factors Relate Increase in age, obesity, abuse of alcohol, diabetes mellitus, hypertension, early onset of menstruation and late menopause, smoking, as well as a burdened family history. Several genes associated with an increased risk of developing breast cancer were allocated. Among them are most famous Genes BRCA1 and BRCA2: The mutation is in them discoveredFor example, Angelina Jolie. After the 1970s, the number of breast tumors increased, researchers associate this primarily with a decrease in the number of children in families and a decrease in breastfeeding time, since both pregnancy and feeding Reduced The risk of pathology.

The occurrence of the idea that cramped underwear provokes breast cancer can be traced with an accuracy of a year with a high degree of probability and even determine its author. In 1995 in the USA I went out The book Dressed to Kill ("dressed for murder") Sydney Ross Singer and Soma Grismayer. It is worth noting that both author did not have a medical education. In their book, they cite the data of a survey of 4700 Americans with breast cancer already diagnosed, and also describe the experience of the catfish itself, which had the same diagnosis. All respondents in their book note that they wore a bra. Based on this, the authors concluded about the connection of linen and illness, explaining that such linen limits the functioning of the lymphatic system, which leads to the accumulation of toxins in the body. It is worth noting that the sample is not transparent, the exact diagnoses of the respondents are not specified, other risk factors are not analyzed. Some critics Markthat, perhaps, the only real patient in the book is Grismeier herself. Summarized by the authors have never been published in scientific journals.

In their subsequent books, the authors nominated a number of controversial judgments: supposedly a dream on an inclined bed can prevent Alzheimer's disease and impotence, frequent defecation and urination can prevent prostate hyperplasia and alleviate the symptoms of menopause, and high pressure, in their opinion, is only a medical scam.

However, the myth not backed up by facts has disassembled quite widely. Authoritative researchers conducted a number of experiments to refute it.

In 2014, a team of scientists examined A group of women: 454 had invasive cancer of the mammary glands, 590 - invasive focal cancer of the chest and 469 were without cancer. The participants were offered a number of questions, including the following: “At what age did you start to wear a bra?”, “What type of braas do you wear?”, “What size of the bra and the size of the cup do you wear?”, “How many hours and days a week do you wear a bra?”. Family and reproductive history was also taken into account. Scientists have not revealed any pattern between the development of pathology and the wearing of a bra with bones.

The official position of the American oncological society also consists of There is no connection between the wearing of the bra and cancer diseases of the mammary gland. US National Center for Health Research Turns Attention to the fact that with compression of the mammary glands, biological fluids move upward, into the lymph nodes in armpits, and not under the chest, as the authors of the book claimed. According to their opinion, attributing harmful effects to everyday things “stems from our desire to control those areas of life in which we have a lot of indefinite or fear. People want to know the culprit, and also hope that, avoiding close bras, they will be able to avoid breast cancer. ” They also give an explanation that could cause such a delusion. Women with a large breast size and excess weight more often wear a bra than women of asthenic physique, while the presence of fat deposits is a factor provoking oncological pathologies.

Harvard Medical School also He thinksthat there is no pattern between wearing linen and cancer. Researchers note that "conversations with women after they developed breast cancer can lead to the bias of memories, especially with respect to data such as the age at which they began to wear a bra." They also focus on the fact that the book included conversations only with those women who had an oncological diagnosis and wore bras.

In addition to scientific data, myth can be refuted by simple logic: breast cancer It happens And in men, but they most often do not wear a bra.

Thus, there is no connection between wearing a bra and developing breast cancer, this is nothing more than a common myth. Having abandoned wearing underwear, it will not work to protect yourself from the disease. At the same time, risk factors include a whole range of phenomena, such as excess weight, alcohol abuse and smoking, which we are quite able to influence.
