Throughout my entire life I’ve always recognize how bad Cancer is, and I’ve always been told that Chemo was a way to cure it. I am aware that cancer is a mutation of cells. But how do stuff like tumours lead to death?

Cancer is an overgrowth of cells. They take over your organs, destroying them, and that is what kills you. Radiation kills the cells with extreme heat, stopping their growth, and chemo is really just mega doses of poison for the cancer. That’s why it makes you so sick. You get some of the poison, too.
Cancer affects organs. If a cancer affects an important organ, let’s say tumours on your liver it can affect its function. Malfunctioning organs will kill you. Radiation breaks down the DNA of cells. If you break down the DNA, the cells have no way of replicating. If the replication is halted, essentially cancer is stopped.
PS: please feel free to correct me if I got anything out of turn.
In basic terms, cancer cells kill because they grow out of control and eventually take over an organ and spread to other organs and affect their function. Radiation kills cancer cells by damaging their DNA. Normal cells can be affected by radiation too, but cancer cells are especially susceptible to damage compared to normal cells due to the fact that they divide/grow quickly.
