Herceptin, blocks HER2 function (Her2 is a type of protein found in 15-20% of all breast cancers which makes the cancer more aggressive). Treatment regimens for Herceptin vary depending on hospital protocols, but for the treatment of HER2+ early breast cancer, treatment is usually continued for one year (up to 18 cycles).
Some women are kept on Herceptin long-term if their cancer progresses. How long a women can stay on Herceptin for is not known. The main concerns with long-term therapy are the potential cardiac side effects of Herceptin.
