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?

Cancer doesn’t specifically kill a person on its own, instead it stops other organs from being able to function properly by basically getting in their way.

So a tumour growing in the brain for example will start putting pressure on the surrounding brain tissue and displacing it – without that brain tissue your brain won’t be able to function properly, and certain faculties will start to fail.

A tumour growing in the stomach or intestines may cause blockages and problems to those organs – block your intestine and you cannot eat, or the tumour could damage the intestine walls and cause bleeding and infection.

Lung cancer will cause tumours to grow in the lungs – blocking the passage of air and limiting the oxygen you can absorb.
