I had bilateral mastectomy with reconstruction and felt ready to return to work around week 6 but I started chemo that week.
Chemo was hard for me. I needed about 8 weeks prior returning to work and went back on half days initially and slowly increased my hours. I continued on herceptin in this time. It probably took me 4 to 5 months to feel ok at full time but required a lot of rest after work. I used to do walks in my breaks to get my fitness back. I work in community nursing and was out in cars a lot so was doing quite a bit of moving around.
