However, along with the dissemination of information, <strong>myths and doubts about the true risk factors for breast cancer<\/strong> also arise.<\/p>\n<h2 class=\"wp-block-heading\"><strong>What really increases the risk of breast cancer?<\/strong><\/h2>\n<p>It is essential for doctors to be well informed to safely guide their patients, differentiating <strong>proven risk factors<\/strong> \u2014 such as <strong>smoking, alcohol, obesity, and physical inactivity<\/strong> \u2014 from those that are often mistakenly associated, such as <strong>hormone replacement therapy (HRT)<\/strong> during menopause.<\/p>\n<p>For years, HRT was pointed out as one of the main causes of breast cancer. However, <strong>new scientific evidence<\/strong> has revised this perspective.<br \/>In a recent panel by the <strong>FDA (Food and Drug Administration)<\/strong>, specialists highlighted that the relationship between HRT and breast cancer is <strong>much more complex than previously thought<\/strong>.<\/p>\n<p>The main conclusion was clear:<\/p>\n<p><strong>HRT, when well indicated and monitored, should not be considered a villain.<\/strong><strong><br \/><\/strong> The risk is <strong>modest and variable<\/strong>, depending on the type of formulation, duration of use, and, most importantly, the <strong>genetic and clinical profile of the patient<\/strong>.<\/p>\n<h2 class=\"wp-block-heading\"><strong>The impact of lifestyle habits on breast cancer<\/strong><\/h2>\n<p>When analyzing population data, it is evident that <strong>lifestyle habits<\/strong> have a much greater influence on the risk of breast cancer than HRT.<\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Smoking:<\/strong> responsible for about <strong>30% of cases<\/strong> of various types of cancer, including breast cancer.<\/li>\n<li><strong>Obesity in adulthood:<\/strong> increases risk by approximately <strong>30%<\/strong>, especially in postmenopause.<\/li>\n<li><strong>Physical inactivity:<\/strong> contributes around <strong>5%<\/strong>, but is directly related to obesity and insulin resistance.<\/li>\n<li><strong>Alcohol consumption:<\/strong> a proven risk factor, impacting even with <strong>moderate consumption<\/strong>.<\/li>\n<\/ul>\n<p>These factors are <strong>modifiable<\/strong> and should be the main focus of prevention strategies.<\/p>\n<h2 class=\"wp-block-heading\"><strong>The role of the physician: information and individualization<\/strong><\/h2>\n<p>More than restricting hormonal therapies that improve quality of life, it is essential that the <strong>physician acts as an educator<\/strong>, helping the patient understand her <strong>real risks<\/strong> and <strong>adopt healthy habits<\/strong>.<\/p>\n<p>Moreover, the risk of developing breast cancer <strong>is not the same for all women<\/strong>. It varies according to family history, genetic predisposition, environment, and lifestyle.<br \/>Therefore, <strong>individualized genetic assessment<\/strong> has become an essential ally in modern medical practice.<\/p>\n<h2 class=\"wp-block-heading\"><strong>Genetics and personalized medicine: the future of prevention<\/strong><\/h2>\n<p><strong>Personalized medicine<\/strong> allows for a better understanding of each patient&#8217;s individual risk.<br \/>Through specific <strong>genetic tests<\/strong>, it is possible to identify <strong>variants associated with breast cancer predisposition<\/strong>, such as <strong>BRCA1, BRCA2, TP53, PALB2, ATM, and CHEK2<\/strong>.<\/p>\n<p>The <strong>MyHormoDNA Breast and Ovarian Cancer Panel<\/strong> is an advanced tool that offers:<\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Increased safety in the prescription of HRT<\/strong>, avoiding unnecessary risks in patients with genetic mutations;<\/li>\n<li><strong>Early screening<\/strong> and establishment of preventive behaviors;<\/li>\n<li><strong>Clinical, ethical, and legal support<\/strong> in accordance with international guidelines from <strong>NCCN, ESMO, and ASCO<\/strong>.<\/li>\n<\/ul>\n<p>This approach promotes a <strong>personalized, safe, and evidence-based medical practice<\/strong>.<\/p>\n<h2 class=\"wp-block-heading\"><strong>Conclusion: it\u2019s time to update the debate<\/strong><\/h2>\n<p>The <strong>debate on HRT and breast cancer<\/strong> needs to be revised in light of current science.<br \/>Hormonal replacement, when well indicated and monitored, <strong>should not be seen as a cause of breast cancer<\/strong>.<br \/>The real focus should be on <strong>modifiable risk factors<\/strong> \u2014 such as lifestyle habits \u2014 and on <strong>individualized genetic assessment<\/strong>.<\/p>\n<p>Do you want to better understand how to assess your patients&#8217; individual risk?<br \/>Contact us and learn about the <strong>MyHormoDNA genetic tests<\/strong>, designed to offer <strong>security, personalization, and clinical precision<\/strong>.<\/p>\n<h3 class=\"wp-block-heading\"><strong>References<\/strong><\/h3>\n<ul class=\"wp-block-list\">\n<li>NCCN Guidelines \u2013 <em>Genetic\/Familial High-Risk Assessment: Breast, Ovarian, and Pancreatic<\/em> (v.2.2024).<\/li>\n<li>ESMO Clinical Practice Guidelines \u2013 <em>Hereditary Breast and Ovarian Cancer Syndromes<\/em> (2023).<\/li>\n<li>ASCO Statement \u2013 <em>Genetic Testing and Cancer Susceptibility<\/em> (2022).<\/li>\n<li>Richards S. et al. <em>Genetics in Medicine<\/em>, 2015.<\/li>\n<li>Brazilian Society of Medical Genetics and Genomics (2024).<\/li>\n<li>Daly MB et al., <em>J Natl Compr Canc Netw<\/em>, 2024.<\/li>\n<li>Kurian AW et al., <em>J Clin Oncol<\/em>, 2014.<\/li>\n<li>Domchek SM et al., <em>JAMA<\/em>, 2010.<\/li>\n<li>Tung N et al., <em>Cancer<\/em>, 2015.<\/li>\n<li>Desmond A et al., <em>JAMA Oncol<\/em>, 2015.<\/li>\n<\/ul>\n<p><em>Prepared by Dr. Francisco Tostes, Scientific Director at Renewal<\/em><\/p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Breast cancer is the most common neoplasm among women worldwide, representing a significant public health challenge.
