| dc.description.abstract | Background. Based on Globocan data in 2020, there were 68,858 new cases of breast cancer, which accounted for about 16.6% of the 396,914 total new cancer cases in Indonesia. The high incidence of breast cancer in Indonesia is not always accompanied by a complete histopathological and immunohistochemical examination. Breast cancer is rare under the age of 40 and women diagnosed with breast cancer under the age of 40 will have a poor prognosis, more aggressive cancer, high malignancy and high mortality rates. Objective. To find out the description of breast cancer patients under the age of 40 at RSHAM in 2020-2023. Method. The research is a descriptive study with a cross sectional design. The sample of this study is breast cancer patients under the age of 40 at RSHAM in 2020-2023 with total sampling technique. Results and Discussion. The results showed that the most common histopathological type is IDC as many as 34 patients (97.1%). The most immunohistochemical sub-type is luminal B as many as 16 patients (45.7%). The highest BMI is normal as many as 27 patients (77.1%). There is no family history of cancer in 35 patients (100%). The most common cancer stage was stage IV with 17 patients (48.6%) and stage IIIB with 14 patients (40%). The most histological grade is histological grade 2 as many as 19 patients (54.3%). Conclusion. The description of breast cancer patients under the age of 40 at RSHAM in 2020-2023 is the IDC histopathological type, luminal B immunohistochemical sub-type, normal BMI, no family history, stage IV, and histological grade 2. | en_US |
