Density and texture as potential complementary mammographic risk markers. It may be hypothesized that measures of the (relative) amount of fibroglandular tissue and measures of the structural appearance of the fibroglandular tissue (density and texture) may both contribute to mammography detected risk. Increasing density and increasing texture may independently add to the risk of breast cancer (visualised as changes from the green colour zone to the light green/light red colour zone). Low density + low texture indicate the lowest mammographic risk (green colour) whereas high density + high texture indicate the highest risk (red colour). Combining these two risk markers could potentially improve risk segregation of screening women
