You're a classy guy aren't you.
There's a huge recovery period with chemotherapy and really they shouldn't even be around large groups. Never mind be put under stress from colleagues using a cancer patient for publicity.
My girlfriend went to a festival during one round of chemotherapy. It depends on the treatment you’re getting of course, but in general you're not just sitting around invalided “with chemotherapy” all the time... in fact you can seem perfectly healthy towards the end of a course.
Colin’s kinda right that the phrasing is a bit weird. Unless she’s actively skipping a course, or coming straight from one when she should be resting - neither of which she should remotely be doing of course, then she’s simply “doing something during the period of time you’re okay doing things” ... in which case it’s a rather gratuitous reference to the fact she’s having chemotherapy.
