Breast cancer is one of the most malignant diseases which are responsible for number of deaths. Number of researches and studies have been under taken on this subject. A new study suggests that true biological differences are exist in breast cancer by ethnicity. These findings have been confounded by Dr. Tim Byers, of the University of Colorado Health Sciences Center, Denver, and colleagues.
It is not due to the disparity in the access in health care among the Hispanic and Caucasian women that differences in the characteristic of breast cancer exist. "These differences include earlier (average) age at diagnosis, later stage of disease at diagnosis, and the presence of tumor characteristics associated with poor prognosis" according to Dr.Byers.
Hispanic women are more prone to be diagnosed with large, belligerent breast cancer rather than the Caucasian white women. In order to study these differences a research was conducted between 1995 and 2004 in the Kaiser Permanente of Colorado Tumor Registry. Here equal access to screening and care was given to both the race of women. Similar kind of mammography screening was also done. The study was done on 139 Hispanic and 2118 Caucasian white women.
The results showed that the average age of diagnoses was notably younger for the Hispanic women as compared to the Caucasian white women. While only 20% was detected under the age of 50 in the Caucasian women, a prominent 31% was found in the Hispanic women. Thus highlighting the fact that true biologic differences exist in breast cancer by ethnicity. Further studies are also being conducted to find if different strategies for different races is needed in the prevention of the breast cancer.
