IBIS software (Tyrer-Cuzick model)
The Tyrer-Cuzick model is a breast cancer risk assessment tool incorporating family history, endogenous hormonal factors, benign disease, risk factors such as age and body mass index, as well as genetic factors (including BRCA) into a single statistical model. The Tyrer-Cuzick model has been shown in independent studies to be the most consistently accurate when compared with other available risk assessment models. The model has been incorporated into a computer programme, the IBIS software that gives a personalised risk estimate. IBIS is available for non-exclusive licensing for stand-alone use or for incorporation into broader software platforms.
