Risk Factors for Breast Cancer

- Age: the older you are, the higher the risk
- Family history: mother, sister with breast cancer

- Menstruation: onset before age 12
- Menopause: onset after age 55
- Prolonged use of estrogen
- Late age at birth of first child or no children

2nd method for MM is

Ultrasound

MRI Indicated for:

- Detecting palpable masses not seen with mammography or ultrasound
- Assessing lesions in an extremely dense, glandular breast
- Possible screening of a young woman at very high risk for breast cancer because of familial history
- Assessing leakage from silicone breast implants
