Abstract:Objective To explore the value of magnetic resonance imaging (MRI) in diagnosis of breast cancer, and analyze the risk factors of breast cancer. Methods Two hundred patients with breast cancer admitted in our hospital were selected as the patient group, and 125 cases of healthy women at the same period checked in our hospital were randomly selected as the healthy group. The positive rate of MRI for different types of breast cancer were determined. Single factor analysis and logistic analysis were used to analyze 10 factors (educational level, occupation, family history of breast cancer, regularity of menstruation, childbearing history, abortion times, breastfeeding time, negative life event, smoking/passive smoking and history of alcohol intake) relations with the breast cancer incidence, in order to identify risk factors. Results The positive rates of MRI for Luminal A, Luminal B, Her2+ and triple negative breast cancer were 96.00%, 98.68%, 100% and 100%. On the whole, the positive rate of MRI was 98.50%. The multivariate analysis results showed that smoking/passive smoking (OR=2.442), abortion times (OR= 2.195), family history of breast cancer (OR=1.923), and the negative life events (OR= 1.817) were the risk factors of breast cancer incidence (P<0.05), while breast feeding (OR=0.585) was the protective factor (P<0.05). Conclusion MRI has a high accurate rate for the diagnosis of breast cancer. Risk factors of breast cancer showed that anti-abortion, breast feeding, refusing passive smoking, and timely screening of genes for women with family history of breast cancer could efficiently reduce the incidence of breast cancer.
