Metrics details. Lobular carcinoma in situ LCIS of the breast is a risk factor of developing invasive breast cancer. We evaluated the racial differences in the risks of subsequent invasive breast cancer following LCIS. The year incidence was 7. Compared to white women, black women had significantly elevated risks of subsequent invasive breast cancer HR 1.

Breast Cancer Risk Factors: Race/Ethnicity
The reasons for these differences are unclear. Breast density, an important risk factor for breast cancer, has not previously been studied here. Linear regression of the natural logarithm of absolute and percent density values was used, back-transformed and expressed as the ratio of the geometric means. Covariates were age, x-ray system and, for absolute density, the natural log of the volume of non-dense tissue a proxy for body mass index.
White women and black women have the highest incidence rate of new breast cancer cases overall [ ]. The lifetime risk up to age 95 and older of breast cancer for women in the U. However, this risk varies by race and ethnic group. Lifetime risk of breast cancer. Adapted from SEER data [ ].
Background Breast cancer incidence is considerably lower among Japanese and Chinese women than among Caucasian and Native Hawaiian even in second and third generation migrants. Mammographic densities, which refer to the radiological appearance of the healthy female breast, are related to breast cancer risk. The purpose of this project was to explore the hypothesis that women from ethnic groups at high breast cancer risk are more likely to have high levels of densities than women from low breast cancer risk groups.
