title: Analysis of odds ratio of increased relative risk of developing breast cancer in different groups of women.
abstract: Taking into account the large number and variety of factors of breast cancer there is constant need and necessity to monitor the risk of developing the disease. It is important to take preventive actions--health education concerning lifestyle and possible ways to modify unhealthy aspects. Quantitive assessment of risk of developing invasive breast carcinoma can be performed using the Gail model (GM). This method is designed to estimate relative and cumulative risk during the entire lifetime or at a certain age of a patient, considering risk factors. It is possible to identify women with increased risk of breast carcinoma and to choose a proper diagnostic path. The purpose of this study was to estimate the relative risk (RR) and to analyze the odds ratio (OR) of increased risk of developing breast cancer. The participants in the study were healthy women with no focal changes in mammary glands and women with diagnosed malignant or benign breast neoplasms. The total number of participants was 555 females aged 35-70 years. The study was carried on in the Great Poland and Lubuskie provinces between 2005 and 2006. High 5-year relative risk of developing breast cancer assessed by the Gail method, proved that this method was a useful tool in confronting reality. In classification of women to a group of increased risk of breast carcinoma, apart from assessment by the Gail method, factors like: BMI, education, medical interventions in puerperium and number of cases of familial invasive cancers should be taken into account.
