Question: Which cancer is the worst ?

This is a very hard question and beyond my expertise area. Having said that, there are some types of cancer that even when diagnosed early and attacked with the latest treatments, they still have the power to kill, for example leukemia (=blood cancer), lung or breast cancer. However, there’s considerable variation, and there are several cases of people who survived even the deadliest types of cancer.
