Is the incidence increasing for young women or are anti smoking measures just reducing rates in old men and thus the overall demographics of those being diagnosed are changing?

Both

> cases among fit, young, non-smoking women have risen, both as a proportion and in absolute numbers

Maybe there are just more fit, non-smoking women now?

Yeah definitely a possibility. The auricle also doesn't give any actual numbers in absolute terms so it might be a tiny increase.
