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

It can rupture blood vessels and cause haemmorhaging.

It can disrupt the function of the organs/structures it invades (eg. having a big lump in your lung makes breathing problematic…)

But one of the biggest effects is that it just floods you with cellular waste-products. You can end up with *pounds* of cancer in you, and the thing about cancer is that its metabolism is turned up to 11 all day errday, so all that tissue is *constantly* pissing in your bloodstream and just plain poisoning you faster than your liver and kidneys can keep up with.
