Certain risk factors, like genetic mutations, specifically BRCA1 and BRCA2 tumor suppressor genes [3,6], obesity (BMI ≥ 30 kg/m2) [3,7], exposure to X and γ radiation [3,7], early menarche, nulliparity, advanced age at first birth and advanced age of menopause [3,6], as well as alcohol consumption, smoking and diet, play an important role in the development of breast cancer [3,7]. The gene discussed is BRCA1; the disease is breast cancer.
