Eli5: How does cancer actually kill people?

Like, I get the cancers that attack vital organs, like lung cancer, but, how exactly does, for example, skin or breast cancer?

There are a number of ways it can do so, but I will list the top 3

1. Interferes with the function of a major organ. The organ needs to do stuff to keep the body alive, having a giant mass in the organ makes that job more difficult like way more difficult.

2. Takes energy from the organ. Cancer is a hungry hungry mass, it uses way more energy than the surrounding tissue and causes the surrounding cells to die from hunger.

3. Interferes with blood and transport of necessary stuff. The cancer can block major arteries and veins and make blood flow stop. Lack of blood will kill the organ.
