You already have the cancer cells so you have a growth that gets bigger and bigger. However, the injected cells express a marker which the immuns system recognise and thus they'll be destroyed like a normal infection. But, the other cancer cells( thos that weren't extracted) will also be recognised by the immune system after the injection and hence they'll also be attacked.
Note that if I were to inject you with a cancer cell the probablity for you to devlop cancer would be almost non-existing. [img]smile.gif[/img]
