An author was more likely to use target words metaphorically when the target sentence relates more closely to their own experience of disease and treatment.
metaphors were relatively frequent when people shared their own disease experience (Topic 0, Topic 9) or sympa-  get, chemo, if, they, as, out, can, like, now, she, feel, did, up, know, think, been, good, time, or, when I'm scared of chemo and ct scans because it makes cancer come back and you become more resistance to treatment with drugs like these later.
