I am unable to say why you have this, as we are not part of your care, but do talk to your team. If the breathlessness is due to your cancer diagnosis then the treatment may well help, as it helps your cancer.
Do talk to your specialist or your breast care nurse (BCN) for more information as they may be able to prescribe you something if your symptoms don't improve.
Take care and if you want to talk to the nurses do call 0808 800 4040. Lines are open mon-fri 9-5.
