A 58 yr old woman with a 20 yr history of smoking has a history of breast cancer in her mother. Her diet is poor in fiber and rich in saturated fats. Menarche occurred at 13 yrs of age and menopause began at 52 yrs of age. She has had 3 children. She had a cervical conization at 28 yrs of age for severe cervical dysplasia and has since had normal cervical Pap smears. Which of the following is her greatest risk factor for the breast cancer? A. Age B. Family hx C. Smoking hx D. Severe cervical dysplasia E. Low fiber, high saturated fat diet So I am debating between A and B. Isn't the age the #1 risk factor for breast cancer?
