ABSTRACT

Introduction: Breast cancer is the malignant neoplasm most frequently diagnosed in women worldwide. Risk factors for this condition include family history, hormonerelated factors, diet and lifestyle, high mammographic breast density, exposure to ionizing radiation and benign proliferative breast disease.
Objective: Identify lifestyle risk factors for breast cancer in a group of women from the Cuban Institute of Oncology and Radiobiology in the period March 2006 to December 2009.
Methods: An epidemiological observational analytical case-control study was conducted of 300 breast cancer cases and 300 controls.
Results: The best represented age group was 55-64 years with 84 patients (28%). No statistically significant differences were found (p=0.3713) with respect to overweight or obese women, smoking (p=0.1648) or time of exposure to this toxic (p=0.2144). However, the opposite occurred with respect to the number of cigarettes smoked per day (p=0.0136). Thirty of the cases versus 211 controls consumed some type of alcoholic beverage, for p<0.001, a statistically significant value. No relationship was found between a family history of breast cancer and occurrence of the disease (p=0.6).
Conclusions: The number of cigarettes smoked per day was found to be a risk factor among patients. No statistically significant relationship was found between obesity, smoking, time as a smoker or a family history of breast cancer. Though alcohol consumption was a protective factor, it was considered to be worthless, since it was not approached deeply from a statistical viewpoint in terms of intensity and frequency.
