OBJECTIVE To evaluate the correlation in temporal trends in obesity and endometrioid endometrial cancer incidence in the United States using two comprehensive national databases. METHODS This is a cohort study in which data on endometrioid endometrial cancer were obtained from the U.S. Cancer Statistics from 2001 to 2018 and corrected for hysterectomy and pregnancy. Data on obesity were collected from the NHANES (National Health and Nutrition Examination Survey) database from 1988 to 2018. Average annual percentage changes (AAPCs) were used to describe trends. Pearson correlation coefficients ( r ) were calculated to examine the relationship between trends. SEER*Stat 8.3.9.2 and joinpoint regression program 5.2.0 were used for statistical analysis. RESULTS From U.S. Cancer Statistics data, 586,742 cases of endometrioid cancer were identified from 2001 to 2018. The average annual increase in endometrioid cancer was as follows: Hispanic 1.37% (95% CI, 1.14–1.60, P <.001), Black 1.30% (95% CI, 1.04–1.57, P <.001), and White −0.17 (95% CI, −0.91 to 0.58, P =.656). Women aged 20–29 years had a 4.48% annual increase (95% CI, 3.72–5.25, P <.001) and women aged 30–39 years had a 3.00% annual increase in rates (95% CI, 2.65–3.36, P <.001). According to the NHANES data, the prevalence of obesity in 2018 in adult women was as follows: Black 56.80%, Hispanic 44.10%, and White 40.90%. An examination of trends by age showed that women aged 20–29 years had the highest annual rise in obesity compared with other age groups (AAPC 7.36%, 95% CI, 4.0–10.8, P <.05). Strong and statistically significant correlations between endometrioid cancer and obesity trends were noted for Black ( r =0.78, P =.01) and Hispanic ( r =0.91, P <.001) women, as well as women aged 20–29 years ( r =0.72, P =.03) and 30–39 years ( r =0.88, P =.001). CONCLUSION The current data demonstrate a temporal association between the increasing incidence of obesity and endometrioid endometrial cancer, and this effect disproportionately affects younger women and Black and Hispanic women.

... One study at Hospital Melaka in Malaysia reported that 44.8% of cases diagnosed were premenopausal women and as much as 16% of EC cases were diagnosed in women <40 years old [2]. In the United States, the incidence of EC in black women aged 35-49 years has increased by 2.8% per year from 2001 to 2019 [11]. ...

... Considering that we included several Japanese cohorts in our review, we can argue that the increased prevalence of p53 mutations found in G3 endometrial carcinoma corroborates this fact. Data on regional differences in endometrial cancer are evolving, and there is a need to adjust studies to the molecular classification of endometrial carcinomas [79]. ...

Failure to meet target HPV vaccination rates among adolescents in communities served by safety-net clinics is of particular concern, as these are the same communities that experience a disproportionate burden of cervical and other HPV-associated cancers. The implementation of evidence-based strategies (EBS) to improve HPV vaccination within safety-net clinics is critical to addressing long-term cancer inequities [9][10][11][12]. ...

... Endometrial cancer incidence was adjusted for hysterectomy prevalence and age adjusted to the 2000 US standard population. As hysterectomy data were only available on even-numbered years from 2000 to 2022 for all jurisdictions, we estimated the hysterectomy prevalence for odd-numbered years by averaging their adjacent even-numbered years using similar methods described elsewhere [21,22]. For example, we estimated the hysterectomy prevalence in 2021 by averaging the prevalence in 2020 and 2022. ...

In 2019, Utah had the highest incidence of distant melanoma among white women, with an incidence rate of 3.45 cases per 100,000. 24 This high incidence aligns with broader trends in the United States, where melanoma incidence has been rising, particularly among older adults. 25 The high prevalence in Hawaii and Utah may be related to lifestyle factors that increase Ultraviolet (UV) exposure, such as outdoor activities and tanning habits. ...

... Upper urinary tract urothelial carcinomas (UTUCs), including renal pyelocaliceal and ureteral cancers, are part of the broader category of urothelial cancers (UCs) alongside bladder cancers (BCs). In Western countries, UTUCs represent 5-10% of UCs (1), and in East Asia, their prevalence can reach up to 43% due to the use of aristolochic acid in herbal medicine (2)(3)(4)(5). These carcinomas are characterized by their deep location and insidious onset, complicating early detection. ...

... Several studies have identified these disparities in accessing cervical cancer screening. For instance, a study conducted in the USA (Chan et al., 2022) revealed that 13.6% (n total= 324) of transgender men had never undergone cervical cancer screening, compared to 5.7% (n total= 201061) of cisgender women (p < 0.01). This difference was more pronounced among younger participants, with only 50% of transgender men aged 18-29 reporting having had screening, compared to 70% of cisgender women (p = 0.011). ...

However, regional disparities in vaccine adoption persist, and cervical cancer remains a substantial concern not only in countries where the HPV vaccine is not widely available but also in countries where the vaccine is commonly administered.
