Breast cancer is one of the most common cancers worldwide both in terms of incidence and mortality. Its incidence has been on an increasing trend in developing nations including Nepal, however, there is very limited evidence of its demographic profile in our setting. This study aimed to find out the prevalence of breast cancer among cancer patients visiting the Department of Internal Medicine of a tertiary centre.
A descriptive cross-sectional study was conducted among cancer patients visiting the Department of Internal Medicine of a tertiary care centre using retrospectively collected data from 1 August 2022 to 30 July 2023 after obtaining ethical approval from the Institutional Review Committee. Histopathologically confirmed cancer patients were included and those with incomplete and duplicated data were excluded. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval.
Among 2067 cancer patients, the prevalence of breast cancer was 102 (4.93%) (4.00-5.87, 95% Confidence Interval). The mean age was 50.51±2.08 years. The most commonly affected age group was 40 to 60 years constituting 61 (59.80%) patients. Histologically, invasive breast cancer of no special type was the most common and was found in 91 (89.22%) patients.
The prevalence of breast cancer was similar to other studies done in similar settings.

乳腺癌是世界范围内最常见的癌症之一，无论是在发病率还是死亡率方面都是如此。在包括尼泊尔在内的发展中国家，其发病率呈上升趋势，但在我们的研究环境中，关于其人口统计学特征的证据非常有限。本研究旨在了解在一家三级中心的内科就诊的癌症患者中乳腺癌的患病率。
这是一项在一家三级护理中心的内科就诊的癌症患者中进行的描述性横断面研究，使用的是 2022 年 8 月 1 日至 2023 年 7 月 30 日期间回顾性收集的数据，在获得机构审查委员会的伦理批准后进行。纳入了经组织病理学证实的癌症患者，并排除了数据不完整和重复的患者。采用便利抽样法。点估计值在 95%置信区间内计算。
在 2067 名癌症患者中，乳腺癌的患病率为 102 例（4.93%）（4.00-5.87，95%置信区间）。平均年龄为 50.51±2.08 岁。受影响最常见的年龄组为 40 至 60 岁，占 61 例（59.80%）患者。组织学上，最常见的是无特殊类型的浸润性乳腺癌，共发现 91 例（89.22%）患者。
乳腺癌的患病率与其他在类似环境中进行的研究相似。
