Abstract
Introduction and objectives
With such a huge country as Saudi Arabia, it would be expected to have variations in the pattern and incidence of breast diseases. This study aims to determine the recent trends in breast cancer incidence rates by age and tumor characteristics among female patients treated in the Armed Forces Hospital Southern Region (AFHSR) from the period of January 2010 to December 2017.
Methods
This study is a retrospective chart review where all breast biopsy reports of female patients were seen between January 2010 and December 2017 at the AFHSR, Saudi Arabia, to observe the pattern of breast cancer as well as to calculate the incidence rates by age and tumor characteristics among the study subjects.
Results
Overall, the incidence rates of breast cancer among female patients ranged between three to eight confirmed cases of breast cancer for every 1000 patients for the period of 2010 to 2017, where the highest incidence rate was reported in the year of 2017. Additionally, two distinct patterns are observed in breast cancer trends, i.e., the most common type of cancer was ductal carcinoma with an incidence percentage of 81.80%, followed by lobular carcinoma (3.40%). There was no statistical evidence that the associated population means of age are significantly different from the type of tumor characteristics.
Conclusions
In this study, the average age for diagnosed women with invasive breast cancer is about 56 years of age while in situ is 51 years. Among women of all age groups, ductal carcinoma is the most common. There is also an increase in the incidence of breast cancer between 2016 to 2017, where the highest incidence rate was reported in the year 2017. Continued vigilance, mammographic screening, and patient education are needed to establish an early diagnosis and perform the optimal treatment.
