I was diagonised in March ( breast cancer IDC grade 2 not spread to lymph node . Finished 1 cycle of FEC then decided to have just EC due to side effect of mouth sores. Now am starting herceptin/Pertuz. Any one with the pertuz and herceptin exeperience ? Because with the first cycle I do get my energy back by the second week . Believe with this starting cycle am so so panicky☹️☹️.
