Hi Casper, I have finished 4 x AC & about to start 12 x Taxol. I have exercised throughout with walking/running twice a week plus a pump class and body combat. I also work 3 days. I did the Encore program & told them I would like to join Dragons Abreast with oncologist's permission & facilitator said no way because I was doing too much. It is hard to know that if you feel ok then why not. I haven't had a problem yet but it is early days. I would think walking would be fine & definitely yoga too & Oncologists have varying opinions as well. Mine is all for exercise but chemotherapy nurse said take it easy!
