Introduction: Breast cancer is the most common malignant neoplasm among women and represents a major public health challenge. The epidemiological analysis of this disease in the state of Pará is essential to understand its regional dynamics and to support policies for prevention, early diagnosis, and more effective treatment.Objectives: This study aims to analyze the epidemiological profile of breast cancer in the state of Pará, with emphasis on identifying the most affected age group and determining the municipality with the highest number of reported cases. Methods: This is a descriptive, quantitative study based on secondary data from the Cancer Information System (SISCAN/DataSUS), focusing on histopathological reports of breast cancer between 2021 and 2024. Only reports with a confirmed diagnosis of malignant breast neoplasm were included, across all age groups. Incomplete or inconsistent records were excluded. The analysis involved the description of absolute and relative frequencies, with an assessment of case distribution by year and municipality. Variables such as year, age group, and municipality were modeled, considering possible confounding factors such as differences in screening coverage across regions. Results: Between 2021 and 2024, a total of 2,329 breast cancer diagnoses were recorded in the state of Pará. A progressive increase in case numbers was observed throughout the period: 387 in 2021, 604 in 2022, 632 in 2023, and 698 in 2024, indicating an upward trend. The distribution of cases by municipality revealed a concentration in five cities: Belém accounted for 998 cases in total (183 in 2021; 260 in 2022; 272 in 2023; 291 in 2024), followed by Ananindeua (253 cases), Castanhal (85), Abaetetuba (65), and Marituba (56). Regarding age groups, the highest numbers of diagnoses occurred among women aged 40–44 (655 cases), 45–49 (698 cases), and 50–54 (737 cases), highlighting the importance of regular screening starting at age 40. Conclusion: The findings of this study allowed for the delineation of the epidemiological profile of breast cancer in Pará, meeting the proposed objectives. Regional disparities in access to diagnosis were identified, with a higher concentration of cases in Belém and surrounding areas. These data underscore the need for targeted actions and provide a foundation for more effective public policies aimed at early screening, improved access to treatment, and the reduction of morbidity and mortality.
It is with great enthusiasm that we present the Annals of the Oncology International Symposium 2025, an event that continues to solidify its significance in the oncology landscape of northern Brazil. Held in Belém, Pará, Oncology 2025 centered around the theme "The cancer control challenge: better knowing it to best facing it," dedicating itself to exploring the latest frontiers in cancer treatment and prevention.
This year, the symposium provided a deep dive into the essential role of knowledge in the fight against cancer, presenting new perspectives and scientific advancements across various areas of oncology. Renowned global experts gathered to share their most recent research and innovative approaches, offering participants a comprehensive view of the challenges faced by healthcare professionals and patients worldwide.
Presentations and discussions during the event focused on critical topics such as the use of new technologies, advancements in personalized therapies, and more effective prevention strategies. Additionally, particular attention was given to the unique challenges faced by the Amazon region, with efforts aimed at developing region-specific solutions to meet local needs.
Beyond being a high-caliber academic event, Oncology 2025 stood out as a moment for integration and professional networking, with the warm hospitality of the city of Belém offering participants a unique experience. This event became a platform for exchanging ideas, where science, culture, and humanity came together in pursuit of a common goal: to improve cancer control both in Brazil and globally.
This collection of abstracts and articles presented during the event reflects the ongoing dedication to research and the development of innovative solutions, highlighting the importance of collaboration and shared knowledge in the fight against cancer.
