I’ve offered to, so I guess it’s up to her. 
Fortunately, this chemo is more a preventative maintenance thing than anything else. Tumor’s already been removed, and it was completely self-contained within the excised portion. Lymph nodes were uninvolved. But this is recommended to prevent it from coming back. (If it did, it would be the third time.)
I’ve lost some to cancer, too, if not such overwhelming numbers. Lost my third wife to breast cancer.
Fortunately, by McCoy’s time, there’s a shot for that. (Bringing the thread back on-topic. [grin])
