My sister’s treatments took at least 4 hours, and that is not counting the time to get there, find parking, sign in, get prepped (have BP and other vitals taken, etc) and then there was the same sort of time to add in after the chemo was done.
It was definitely a whole day thing, and she was often very tired and needed help around the house & time off work for at least the next day.
She had triple-negative early stage-4 breast cancer, and one of the chemo treatments was called “the Red Devil” and it was a toughie!
adriamycin..... the red devil one
Indeed I can see the day being tough, but a whole week? Most people don’t get treatments every day or even weekly. They seemed to be implying he was really on”vacation”….more than 1 day.
My sister, may she RIP, had inflammatory BC and basically never had treatments more than every 3 weeks. The concoction changed, too, So it could affect differently. She mostly was just overcome with exhaustion the next day (not same day) then up again until the next round.
