{"title":"Untangling the mystery of rising breast cancer rates","authors":"Bryn Nelson PhD,&nbsp;William Faquin MD, PhD","doi":"10.1002/cncy.70026","DOIUrl":"10.1002/cncy.70026","url":null,"abstract":"&lt;p&gt;After invasive breast cancer rates declined sharply in the early 2000s, clinicians cheered what seemed to be a major trend. The drop paralleled a big decline in the use of hormone replacement therapy among postmenopausal women after an influential study—the Women’s Health Initiative—found an association between estrogen–progesterone therapy and an increased risk of breast cancer and heart disease.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;The overall incidence, however, soon leveled off and then began to rise again, with troubling increases over the decade ending in 2021, especially among women younger than 50 years and those of Asian American/Pacific Islander (AAPI) or Hispanic heritage. The highest relative increase, in fact, has occurred among women in their 20s and 30s. Researchers have launched investigations into a complex stew of mitigating and contributing factors—from increases in obesity and alcohol consumption to shifting reproductive patterns and earlier ages at first menstruation—but have yet to determine which are playing the biggest roles.&lt;/p&gt;&lt;p&gt;Although overall mortality rates continue to fall, they remain elevated for Native American and Alaska Native women in particular and for Black women. Changing that dynamic may require not only untangling the complex mix of molecular and environmental risk factors but also improving mammography methods and expanding access to medical care for underserved populations.&lt;/p&gt;&lt;p&gt;One of the biggest challenges has been understanding which factors are influencing breast cancer rates across the board and which are associated with particular risk groups. According to a 2024 report led by researchers at the American Cancer Society (ACS), the upswing in estrogen or progesterone receptor–positive (hormone receptor–positive) malignancies accounted for most of the recent increase in breast cancer incidence (the ACS publishes &lt;i&gt;Cancer Cytopathology&lt;/i&gt;).&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;The first author, Angela N. Giaquinto, MSPH, an associate scientist II in the ACS Surveillance Research Program, says that changing reproductive patterns have likely contributed to that upturn. “Having fewer children and/or having children later in life increases breast cancer risk by increasing lifetime exposure to estrogen, which is the driver for most breast cancers,” she explains. “However, pregnancy has a dual effect on breast cancer risk; risk is increased during pregnancy and in the first 5 years following childbirth and is only reduced after about 2 decades compared to those who have not given birth.”&lt;/p&gt;&lt;p&gt;That seemingly contradictory risk pattern may be mediated by changing hormone levels during and after pregnancy. Although the hormone levels likely play a role in the increased postpartum risk, Giaquinto says, “the biological mechanism is not fully understood.”&lt;/p&gt;&lt;p&gt;Adetunji T.

That amount included approximately $26 billion to researchers for the direct costs of conducting their work and an additional $9 billion to cover indirect costs, such as maintenance, utilities, rent, personnel, shared facilities, and other necessary expenses borne by the research institutions. As the Association of American Cancer Institutes (AACI) has phrased it, “indirect costs are what ‘keep the lights on’ at many of our nation’s premier research facilities.”&lt;/p&gt;&lt;p&gt;Each institution negotiates its percentage rate for indirect cost reimbursements with the NIH based on factors such as the local rental market and other overhead expenses; the rates generally vary from 30% to 70%. In February 2025, however, the Trump administration announced a new formula capping all reimbursements at 15%, regardless of location. Among the many research organizations decrying the move, the AACI charged that the cut “would be devastating for the patients our cancer centers serve and would stifle progress against cancer.”&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt;&lt;/p&gt;&lt;p&gt;The Trump administration has cast the controversial rule as a cost-conscious move that will save the NIH an estimated $4 billion annually. As a rule of thumb, though, economists have suggested that every $1 spent by the institutes yields roughly $2.50 in economic activity. The cuts, in other words, could wipe out $10 billion in economic activity, resulting in a $6 billion net loss.&lt;/p&gt;&lt;p&gt;Research administrators such as Prakash Nagarkatti, PhD, a professor of pathology, microbiology, and immunology at the University of South Carolina, say that their indirect cost reimbursements are closely tracked and monitored. “It’s not like it just goes into a bucket and disappears,” he says. In a perspective piece in &lt;i&gt;The Conversation&lt;/i&gt;, he and his wife, Mitzi Nagarkatti, PhD, also a professor of pathology, microbiology, and immunology at the university, further assert that the funding cuts will hit hardest in red states, rural areas, and underserved communities.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; To explain why, they point to a huge geographic disparity in which 27 states receive 94% of all NIH funding. That leaves the remaining 6% of funds to be divided among 23 states—including the 18 least populous ones—and Puerto Rico.&lt;/p&gt;&lt;p&gt;Dr Prakash Nagarkatti says that more rural states with smaller economies and a relative lack of investment, infrastructure, medical centers, and research universities can struggle to be competitive in NIH","PeriodicalId":9410,"journal":{"name":"Cancer Cytopathology","volume":"133 6","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cncy.70021","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144197029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Early detection is critical for improving survival and outcomes because its tumor origin, treatment, and prognosis differ completely from papillary thyroid carcinoma. However, the low incidence of MTC and its variable cytomorphology can pose significant diagnostic challenges for cytopathologists. Referred to as the <i>great mimicker</i>, MTC can resemble various primary and metastatic tumors, complicating its identification, particularly in fine-needle aspiration (FNA) biopsies. Reported FNA sensitivity for a specific MTC diagnosis varies widely from 12.5% to 88.2%, with a 2014 meta-analysis estimating an overall sensitivity of 56.5% when including suspicious lesions. False-negative FNA results, often caused by misinterpretation of cytologic features or inadequate specimen quality, can lead to delayed or suboptimal treatment. Pathologists must be familiar with MTC's diverse cytopathologic presentation and maintain a low threshold for additional diagnostic tests to ensure an accurate preoperative diagnosis.

In HGUC cytology cases, the CIS category had larger nuclear areas than HGUC for both suspicious (116.3 vs. 100.4 µm²) and atypical cells (101.5 vs. 82.2 µm²).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>AIxURO provides objective quantification of N/C ratios and nuclear areas, refining TPS criteria for distinguishing suspicious from atypical cells. A lower N/C ratio cutoff (0.66) for SHGUC/HGUC may be more appropriate than the TPS threshold (&gt;0.7). Findings support using consistent N/C ratio criteria across UUT and LUT cases.</p>\u0000 </section>\u0000 </div>","PeriodicalId":9410,"journal":{"name":"Cancer Cytopathology","volume":"133 5","pages":""},"PeriodicalIF":3.2,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cncy.70017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143902832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
