Abstract
A retrospective data set was obtained from a government University Teaching Hospital for breast cancer patients classified by the cause of death. The first cause of death was cancer while the other cause arose from any other, all of which were put together and referred to as the competing risk. Appropriate probability distributions were fitted to the time-to-death data of the two groups. The three-parameter Weibull distribution was appropriate to the patients who died of cancer, while exponential probability distribution fitted the breast cancer patients who died of other causes. The implication of this distribution is that survival chance changes between the two competing risks such that overtime other causes of death overshadows death arising from breast cancer.
