Idk if this is outside the scope of this blog but: could surviving childhood cancer be a traumatic event for a character? And if so, how?
Medical trauma is absolutely a thing.
And I’m not entirely sure what you mean by how but I suspect it means ‘how does this affect them.’ I’m going to advise you to look up trauma reactions in general and look at first person references for cancer specifically.
New York Times did an interview. (Link)
This is a blog by a person who had cancer. (Link)
Also, articles about it from groups that help out with cancer:
Livestrong has an article about life after cancer here. (Link)
This one by Journey forward deals with learning to cope. (Link)
Here’s a thing about life after childhood cancer. (Link)
Cancer.Net has a thing about it as well. (Link)
As does the American Cancer Society. (Link)
Cancer Today touches on it too. (Link)
Now, the things about life after childhood cancer are often going to be directed at loved ones/the family or they’re going to be about the stats of remission/other side effects of treatment.
But rarely in life are any of us going to find a first person reference that meets what we need exactly, which is why it’s important to do a lot of research and combine what you can to make the picture that you need.
Hopefully that helps a bit,
