Less is more. Stay pure. Stay poor.

It is a time to event model, meaning it controls for time when calculating the hazards. Logistic reg does not take time into effect. It also allows you to control for covariates and competing events (getting hit by a car which prevents you from getting cancer). You should read a research paper on breast CA treatments, so you can see the model in action.
