Answer:
Cancer is a traumatizing event in people's lives, and it is only natural that it
will exact an emotional toll upon those whom it afflicts.
Step-by-step explanation:
Depends on who is going to read it. If a patient is going to read it, he or she will hardly care if it has metastasized. What matters is even if it has, can it be treated.
If a medical professional is reading it, they will know exactly what the meaning of metastasized is, and they will be very concerned about the stages and the treatment for each stage.
I don't like the second one, but it is likely the answer. As a patient, I would despise an answer like that one offered to me (and yes I do have cancer, and it is treated).
I also believe if this is for a general magazine that the last one is an acceptable answer. It's bland, but it works if it is followed by something meaningful.
