When you have a cancer fighting agent in your blood naturally, what is that called?

Not aware of any!: As such there is no known cancer fighting agent in our blood. But our immune system does play an important role and provides us some protection from developing cancer but it is not a complete protection and we are unable to measure this protective effect or factor, like you have wondered about. Perhaps in future we might be able to quantify such a immune protection factor(s).
