It’s all very variable, I went back to work after a week off after surgery (mastectomy, no reconstruction). I do tend to heal quickly and the only complication was a persistent seroma, which was a perfect nuisance but painless and didn’t stop me working. I had six months of chemo (not
triple negative) and I worked through - I took a full day off for my first four treatments (A/C) but went back to work after morning sessions for Taxol weekly. BUT I didn’t get any nausea or fatigue. Either of those can make a huge difference. I didn’t find I had any increased susceptibility to general workplace germs but hospitals and COVID are a different issue. Plan A and Plan B seem to be the best idea. I worried about chemo brain, fatigue and throwing up. Never happened. Didn’t worry about lymphoedema, an arrhythmia or peripheral
neuropathy.....which all happened, but by that time I was a bit more practised at dealing with stuff and none of them have had a major impact on my life, working, travelling etc. Didn’t worry about COVID either which has had an impact. If you get my drift, plan as best you can but don’t get ahead of yourself by worrying about things that may never happen. Cancer is never a good thing but it does teach you about dealing with what is rather than what might be. Best wishes.
