> I’m not sure why genetic testing is suggested here?
I think the first genes identified that had an influence on cancer prevalence were breast cancer genes BRCA1 & BRCA2. These genes also have an influence on men getting prostate cancer.
This article explains more:

Are there any practical implications though, or is this just basically finding something to blame?
Lots of people surely have these genes but no breast cancer, and many or even most cases of breast cancer don't involve this genetic variant.
