Wrong. Fact is something that can be proven and also disproven. Fact is not necessarily the truth. There is no perfection in the world. The fact is called "Error" when disproven. Until then, it is a fact; however, fact is not always 100% proven.
Theories are fact because they start from hypothesis which keeps succeeding which turns into theories. Theories are proven many times, therefore fact, and can be disproven too if it comes to disproval. These are facts, not opinions.
Today, we have a better way of checking cancer such as Magnetic Resonance Image that can picture anything in your body from ALL sides, such as looking from your head, every inch, every nanometers. You see, all things are facts if they can be proven.
MindArchon, science isn't really 100% truth, because there might be a better definition to it, and always there is.

Both of us are correct in a sense. Fact has several definitions. I am sticking to mine, and you are sticking to yours.
Facts can be disproven, and it is an error. However, when the fact is originally established, we still use certain information provided originally. I think the difference between a theory and a fact is that the people who create the theory generally recognize that there is a plausible chance of it being disproven.
People who declare things of facts are certain it is true, and they have information to back it up. If the information is declared as false, then the fact is error.
Even with a MRI, there is still a chance it is not cancer (even if its a very very very small chance), and doctors will still admit this. Therefore saying somebody has cancer is still a theory. However, if they perform surgery (or an autopsy), this will provide more information, would may lead to fact.
