I was interested in learning more about Mammosite so I went in for a second opinion on my DCIS. This doctor is a fellowship trained breast surgeon at the only place around here offering Mammosite 5-day therapy. She told me I am not a good candidate for Mammosite, which is fine; I just felt I should look into it. Anyway, she did ask me if I'd had an MRI yet. The first surgeon I went to feels that they do not provide much of a benefit to women in my situation (46, no family history of breast cancer, lesion < 1 cm.) I have an individual insurance policy with a hefty co-pay so while I want great treatment, I also want to be sure I am not spending a couple of grand for what my first surgeon considers a slim margin of benefit. Does anyone have any input that may guide me here?
