Hi - I'm new to the forum, have been living with Secondary Breast Cancer since June 2014 and up until recently, have been doing well on Herceptin and Pertuzamab. Over the past 6 months, this has stopped working quite so well and now as of next week I will be switching to Kadcyla. Would welcome any information from those who have taken or are on this treatment and how they have found it. Side effects etc. Thanks very much.
