I LOVE my port. It will be 9 years old next month and it's like a Timex, takes a licking and keeps on ticking. Since it was put in, I have had two mastectomies, developed lymphedema in one arm and won't let them touch the other.
I was in the hospital last month, on some strong antibiotics for 8 days, and my port saved the day. In fact, when I had my second mastectomy, the side that the port was on, my main concern with my surgeon was that he save my port.
The port took several weeks to settle down but once it did, it has been a Godsend. I urge you to have the port put in and keep it until you see where this miserable disease is going. Damage to the veins could be permanent from chemo among other substances you will be injected with. It's just not worth chancing it.
Now sing with me, ladies: Zippity Do Dah, Zippity A, Love my port each and every day.
