Cory's mom can limit her alcohol consumption because research shows even small amounts of alcohol can increase your risk. She can not smoke, as smoking increases the risk of breast cancer in premenopausal women. She can be physically active and maintain a healthy weight, as being overweight/obese increase a woman's chances of developing breast cancer, especially those who are postmenopausal. Lastly, she could limit exposure to hormone therapy, as combination hormone therapy (think birth control pills) for more than 3-5 years can increase a woman's risk of developing breast cancer.
