I have an aunt who has had breast cancer for the last year or so. AFAIK treatments so far have been successful but I've just been told that she is going on Herceptin All I know is she has to go in once every three weeks for 17 treatments.
Someone tried explaining it to me earlier but I don't understand it at all, so I was hoping someone on TSR could tell me what it is and why it is needed

Antibodies are molecules from the immune system that bind selectively to different proteins. Trastuzumab(Herceptin) is an antibody that binds selectively to the HER2 protein. When it binds to defective HER2 proteins, the HER2 protein no longer causes the breast cells to reproduce uncontrollably. This increases the survival of people with cancer. However, cancers usually develop resistance to trastuzumab.
The reason why it's been in the news a lot is because it's very expensive, like 50 grand per year of treatment. As far as I know, its only really effective in later stages of breast cancer so it's not suitable for everyone.
Hope this clears things up a little for you
