Abstract
Background Female breast cancer remains the most common malignant disease and a leading cause of death worldwide. We aim to follow up on the annual dynamics of its incidence, prevalence and mortality rates in the region of Varna, Bulgaria. Methods Data for the recent retrospective analyses was accessed through the information system of Marko Markov Specialized Hospital for Oncological Diseases of Varna for 2017-2021 and two most recent publications for 2013-2017, in accordance with the Medical University-Varna Ethical committee guidelines. Results The total number of newly registered cases of breast cancer in women aged between 24 and 95 years amounted to 1,341. Mean crude incidence rate in 2017-2021 was 108.83 per 100,000, ranging from 119.89 to 105.25 per 100,000 in 2017 and 2020, respectively. The age group of 61-70 years was most affected (26.55% of the cases). Mean crude prevalence rate during this period was 1496.32 per 100,000, varying from 1447.75 to 1549.71 per 100 000 in 2017 and 2020, respectively. The total number of deaths until the end of 2022 reached 310 with 2018 being the greatest in mortality rate (30.22% of the cases). In 2017-2021, bilateral breast cancer was diagnosed as synchronous in 15 women and metachronous in 9 women. Conclusions The regular regional epidemiological investigations could contribute to the enhancement of the effectiveness and quality of prevention, timely diagnosis and adequate complex treatment.
