Hi-I am 36, had a lumpectomy(<1cm), chemo finished July 20th, and almost halfway through radiation. I tested HER2 positive and my Dr. is recommending Herceptin every week for a year and a portacath. I live in a rural area and I know that they haven't had many patients do this as a preventative. Basically, I'm just trying to find out the usual protocol for Herceptin treatments as a preventative. How much of a window after chemo before starting Herceptin is there? Are portacath's the usual? Can treatment be every 3 weeks instead of every week? Should a heart echo be done 1st, especially after A/C? And what types of side effects are most girls experiencing? Just any info at all would be really appreciated-thank you!!!!!
