For example, if someone discovers they have breast cancer or cancer in the liver or something, does that mean that they always had cancer but it was not able to be detected until they discovered they had it? Or is that something that is formed later, and wasn’t always in that person’s body?

it forms at some point, but it can lay dormant/not affecting the human for a while. it’s why we do screening for breast cancer, for example. it’s a build up over time
