Risk factors of breast cancer include female gender, old age, inherited mutations (such as BRCA1 and BRCA2), family history of breast cancer, high breast tissue density, overweight or obese after menopause, use of menopausal hormone therapy (MHT), physical inactivity, and alcohol consumption (Global Cancer Facts & Figures, 2nd Edition, American Cancer Society). Here, BRCA2 is linked to breast carcinoma.
