Hi @Kylie73 I am really sorry to hear about your diagnosis and can appreciate how you must miss your usual cardio regime and HIIT and all the wellbeing benefits those great activities can bring.
As the other ladies have said pausing all but gentle exercise or walking tends to be recommended so we have the best chance of post-surgery healing and recovery.
I only had a lumpectomy (no lymph node removal) but because I also had pre-surgery chemotherapy, and side effects from that, I found an oncology rehabilitation physio program was really helpful.
After seeing the breast surgeon at 6 weeks and getting her clearance I was able to continue a workout that focused on using moderate weights, balancing and strength exercises in my legs and stamina.
Because I also had radiotherapy, the exercise program factored in possible side effects or discomfort.
Having the support of qualified cancer rehabilitation exercise physiologists also gave me a bit of confidence and motivation.
I was made aware of this program by a physio friend but it turned out my oncologist was also aware of it and she referred me into the program.
I can see BCNA has a link to oncology physio rehabilitation too
