Risk factors for pathologically confirmed benign breast disease

Area of Science:

• Epidemiology
• Oncology
• Reproductive Health

Background:

• Benign breast disease (BBD) shares risk factors with malignant breast disease.
• Understanding BBD risk factors is crucial for early detection and prevention strategies.

Purpose of the Study:

• To identify key risk factors associated with benign breast lesions.
• To investigate the relationship between reproductive history, hormonal treatments, and BBD risk.

Main Methods:

• A case-control study was conducted with 288 women diagnosed with benign breast disease and 285 age-matched controls.
• Data collected included menstrual and reproductive history, marital status, education, medical history, and hormonal contraceptive use.

Main Results:

• Nulliparity, late age at first birth, and late menopause were significantly associated with increased BBD risk.
• Early menarche showed a non-significant increased risk. Oral contraceptive use was not linked to increased risk; long-term users showed lower risk.
• No association was found between body mass index and BBD risk.

Conclusions:

• Reproductive factors play a significant role in the risk of developing benign breast disease.
• The findings suggest similarities in risk factors between benign and malignant breast diseases.
• Current data do not support oral contraceptives as a risk factor for BBD.
