One thing I’m worried about Kaleigh: she has a co-morbidity, I think. She had breast cancer and so may have needed chemo. Having had chemo is not good for the immune system (not sure how long lasting that co-morbidity is though).
She did not have breast cancer. She has a prophylactic double mastectomy because she has BRCA-1 gene (I believe that is the specific gene in her case). Her mother had breast CA, but the press secretary has never had CA.
