Answer 1

Imagine it like this

your body is a car and cancer cells is paint on the windshield (organ)

Except this paint drop on the windshield starts growing, and growing. Every time you wipe it off it continues growing if at least one drop is left.

Eventually the windshield is covered by paint and you cant see where you are driving and crash

This is kinda what happens, the cancer cells invade an organ and just hog space. The organ now has less space to carry out its function, and eventually the cancer spreads enough that the organ can no longer carry out its function, and you die from whatever that entails.

Ie if the cancer cells hog space in your lungs and prevent that from working, you are likely gonna die from respiratory failure.
