Hi yes everyone is different.
I saw a physiotherapist specialising in breast cancer patients after my DIEP surgery ( she was referred by my breast care nurse) and she helped me with some very targeted exercises but also I went back to modified Pilates 8 weeks post surgery after checking with my surgeon.
I started walking as soon as I got home from hospital , a bit more each day .
I guess you know the benefits of exercise both mental and physical and there is research that regular exercise does help prevent recurrence.
Take care 🌺
