Some patients may inherit genetic mutations that increase the risk of developing breast cancer, such as BRCA1, BRCA2, TP53, and PALB3, among others [12]. Identification of genetic mutations and understanding the clinical and pathological aspects are crucial for promoting tailored treatment approaches, frequent screening, and the need for prophylactic surgery (for the patient) and genetic counseling for the patient's first-degree relatives. The gene discussed is BRCA1; the disease is breast cancer.
