As the title says, I want to know how does cancer form and expand on the body and why is it so hard to treat sometimes.
Pd: I’m sorry if I wrote something incorrectly, english is not my first language.

This is my layman’s knowledge, I’m sure there are professionals that can answer better. But:
Your cells have instructions for how much they should multiply and where. Sometimes there are mutations that make those instructions corrupt, so they’ll continue multiplying and create things like tumors. They also might do things that those cells don’t normally do. In worst case scenarios, they expand into different parts of your body making them especially resistant to treatment.
