Abstract

This paper presents an overview of the Breast Cancer Risk Assessment (BCRA) Tool, assessing the credibility of the BCRA tool in estimating the risk of developing breast cancer for Asians and the carrying out of tests to identify the changes in the risks that follow with changes in one or more risk factors of the tool. It is essential to increase the awareness of women of their risk of developing breast cancer, as it is not surprising that some women may not even be conscious of the individual factors that might contribute to the increase of their risk of developing breast cancer. On the other hand, relatively accurate means of determining increases in relative risks of developing breast cancer due to changes in some of the risk factors are also important. This is done so that unnecessary worry due to an overestimation of an individual's risk of developing breast cancer can be avoided. Due to the origin of the BCRA tool which is used in this study, it is important to verify the validity of the tool on Asians and to identify, as far as possible, the effect that each risk factor has on individuals. The effect that a specific risk factor has on a white woman may not be exactly the same for that of an Asian woman. As the above-mentioned tool has been arrived at using the statistics and databases of white women, in this work, tests have been carried out to determine the suitability of the tool on Asian women. On top of that, various tests are also carried out to determine the effects of the change of certain risk factors on a woman's risk of developing breast cancer. These factors include age, number of breast biopsies and number of first-degree relatives with breast cancer. Five-year risks and lifetime risks are also looked into separately with the change of each of these factors.
