portacath

Hi-I am new to this site, but very thankful it is available. I have already learned a lot. I have recently found out that I am HER positive. I'm trying to find others like me that have started herceptin. I have had lumpectomy, A/C and am currently doing radiation. I am 36 years old. It was Stage I breast cancer. Just found lump in March 2005 and doctors want me to start herceptin for a year, every week. My question is, how many women are doing this as a preventative measure in the beginning? My nurse said that they would put a portacath in me. That sounds scary to me for a whole year. Has anyone else had to use a portacath for herceptin treatments for a whole year???? Thanks!!!!!!!!
