Women with family history of breast cancer: how much are they aware of their risk?

Abstract

The aims of this study are to assess knowledge of inheritance characteristics of breast cancer and risk reduction strategies and to determine risk perception and the factors affecting risk perception of women with family history. There is a gap in our understanding of risk perception and knowledge of genetic aspect of breast cancer and risk reduction strategies in women with a family history of breast cancer. The study design is descriptive cross-sectional study. Between January 2015 and 2016 at a training and research hospital in Turkey, 117 women who were the first- and second-degree relatives of breast cancer patients were included in the study. Perceived risk scale, cancer worry chart, and a knowledge assessment form were used to collect data. of the women, 34.1% were first-degree relatives of a breast cancer patient, and knowledge score was 6.9 +/- 2.19 out of 11. Almost half of the women (41.9%) moderately worry about the chances of getting breast cancer, and half of the women (51.3%) ranked their perceived risk as moderate (26-50% out of 100%). There is a significant difference between the perceived risk and educational level, having genetic testing, and a significant relationship between the perceived risk and worry level of women. However, breast cancer screening behavior was not affected by risk perception. The knowledge of women regarding inheritance characteristics of breast cancer and risk reduction strategies was moderate, but still majority of women have moderate or higher level of risk perception and are worried about getting breast cancer. Therefore, interventions should be planned to reduce worry and to increase risk reduction strategies such as screening and other health behaviors in women at risk for breast-ovarian cancer.
