Hi Claudia, everyone's bodies are different so it's best to get personalised information about what you can and can't do. Even just one session with a trainer who is experienced in this area so they can ask the appropriate questions and test your abilities is really worth it.
I only had a lumpectomy, but I remember my doctors face when I asked if I could go back to boxing after surgery. Hehe, he was shocked and said he'd have to ask (he was an registrar). I added …. "oh don't worry, I don't punch anyone or get punched". So you may have to clarify with them.
Boxing is awesome for focussing my mind and clearing my head. I love it :smile:
